Malware Uses Router LEDs To Steal Data From Secure Networks (bleepingcomputer.com)
An anonymous reader writes: Researchers from the Ben-Gurion University of the Negev in Israel have developed malware that when installed on a router or a switch can take control over the device's LEDs and use them to transmit data in a binary format to a nearby attacker, who can capture it using simple video recording equipment. The attack is similar to the LED-it-GO attack developed by the same team, which uses a hard drive's blinking LED to steal data from air-gapped computers. Because routers and switches have many more LEDs than a hard drive, this attack scenario is much more efficient, as it can transmit data at about the same speed, but multiplied by the number of ports/LEDs. Researchers say they were able to steal data by 1000 bits/ per LED, making this the most efficient attack known to date. The attack worked best when coupled with optical sensors, which are capable of sampling LED signals at high rates, enabling data reception at a higher bandwidth than other typical video recording equipment. A video of the attack is available here. -
Google's Top Search Result For 'Target' Was A Tech Support Scam (bleepingcomputer.com)
An anonymous reader quotes BleepingComputer: Malicious ads displayed in Google search results for Target -- the US retailer -- redirected users to a tech support scam. The malvertising campaign was spotted on Friday by a US user who posted his observations to a StackExchange thread. The rogue ad appeared when users searched for the term "target," right at the top of all search results, [and] used a feature of the Google Ads service that allows ad publishers to display a URL but redirect users to another link. For example, in the rogue ad, the displayed link was "target.com," but users were redirected to "tech-supportcenter.us." Surprisingly, this got past Google's ad quality control service... The page users landed on was mimicking the style of Microsoft's real website, but was urging users to call a phone number to remove a non-existent "HARDDISK_ROOTKIT_TROJAN_HUACK.EXE" file.
The article points out the same thing happen in February when Google's top search result for Amazon was a spoof site with another tech support scam. -
Insecure Hadoop Servers Expose Over 5 Petabytes of Data (bleepingcomputer.com)
An anonymous reader quotes the security news editor at Bleeping Computer: Improperly configured HDFS-based servers, mostly Hadoop installs, are exposing over five petabytes of information, according to John Matherly, founder of Shodan, a search engine for discovering Internet-connected devices. The expert says he discovered 4,487 instances of HDFS-based servers available via public IP addresses and without authentication, which in total exposed over 5,120 TB of data.
According to Matherly, 47,820 MongoDB servers exposed only 25 TB of data. To put things in perspective, HDFS servers leak 200 times more data compared to MongoDB servers, which are ten times more prevalent... The countries that exposed the most HDFS instances are by far the US and China, but this should be of no surprise as these two countries host over 50% of all data centers in the world. -
CIA Malware Can Switch Clean Files With Malware When You Download Them Via SMB (bleepingcomputer.com)
An anonymous reader quotes a report from Bleeping Computer: "After taking last week off, WikiLeaks came back today and released documentation on another CIA cyber weapon. Codenamed Pandemic, this is a tool that targets computers with shared folders, from where users download files via SMB. The way Pandemic works is quite ingenious and original, and something not seen before in any other malware strain. According to a leaked CIA manual, Pandemic is installed on target machines as a "file system filter driver." This driver's function is to listen to SMB traffic and detect attempts from other users to download shared files from the infected computer. Pandemic will intercept this SMB request and answer on behalf of the infected computer. Instead of the legitimate file, Pandemic will deliver a malware-infected file instead. According to the CIA manual, Pandemic can replace up to 20 legitimate files at a time, with a maximum size of 800MB per file, and only takes 15 seconds to install. Support is included for replacing both 32-bit and 64-bit files. The tool was specifically developed to replace executable files, especially those hosted on enterprise networks via shared folders. The role of this cyber weapon is to infect corporate file sharing servers and deliver a malicious executable to other persons on the network, hence the tool's name of Pandemic. -
Motorcycle Gang Busted For Hacking and Stealing Over 150 Jeep Wranglers (bleepingcomputer.com)
An anonymous reader writes: "The FBI has arrested members of a motorcycle gang accused to have hacked and stolen over 150 Jeep Wranglers from Southern California, which they later crossed the border into Mexico to have stripped down for parts," reports Bleeping Computer. What stands apart is how the gang operated. This involved gang members getting the Jeep Wrangler VIN (Vehicle Identification Number), accessing a proprietary Jeep database, and getting two codes needed to create a duplicate replacement key. Gang members used one code to cut the key, while they used the second code while stealing the car, connecting a handheld programming computer to the car, and programming the replacement key's chip, synchronizing it to the car's dashboard. All of this took under 2 minutes and was also possible because Jeep Wranglers allow thieves to pop the hood from the outside of the car and disable the alarm even before using their non-authenticated replacement key. Officials say that all the database queries for the stolen VIN codes came from a Jeep dealer in Cabo San Lucas, Mexico. Court documents don't say if the dealer cooperated or gang members hacked its system. The motorcycle gang's name was Hooligans and the sub-unit that stole the Jeeps was named Dirty 30. -
Google Chrome Bug Lets Sites Record Audio and Video Without a Visual Indicator (bleepingcomputer.com)
New submitter aafrn writes: "Ran Bar-Zik, a web developer at AOL, has discovered and reported a bug in Google Chrome that allows websites to record audio and video without showing a visual indicator," reports BleepingComputer. "The bug is not as bad as it sounds, as the malicious website still needs to get the user's permission to access audio and video components, but there are various ways in which this issue could be weaponized to record audio or video without the user's knowledge. The bug's central element is a 'red circle and dot' icon that Chrome usually shows when recording audio or video streams." Bar-Zik discovered that if the JavaScript code that does the actual audio and video recording is launched inside a small popup, the icon is not shown anymore. This opens the door for various types of scenarios, where an attacker that has tricked a user into granting him permission to record audio and video records user data but when the user doesn't expect this (no visual indicator). For example, an attacker could disguise audio/video recording code inside popup ads. If the user doesn't close the popup, the popup continues to stream audio and video from the victim's house. Google declined to consider this a security bug. -
SSD Drives Vulnerable To Rowhammer-Like Attacks That Corrupt User Data (bleepingcomputer.com)
An anonymous reader writes: NAND flash memory chips, the building blocks of solid-state drives (SSDs), include what could be called "programming vulnerabilities" that can be exploited to alter stored data or shorten the SSD's lifespan. According to research published earlier this year, the programming logic powering of MLC NAND flash memory chips (the tech used for the latest generation of SSDs), is vulnerable to at least two types of attacks.
The first is called "program interference," and takes place when an attacker manages to write data with a certain pattern to a target's SSD. Writing this data repeatedly and at high speeds causes errors in the SSD, which then corrupts data stored on nearby cells. This attack is similar to the infamous Rowhammer attack on RAM chips.
The second attack is called "read disturb" and in this scenario, an attacker's exploit code causes the SSD to perform a large number of read operations in a very short time, which causes a phenomenon of "read disturb errors," that alters the SSD ability to read data from nearby cells, even long after the attack stops. -
10 Years Later: FileZilla Adds Support For Master Password That Encrypts Your Logins (bleepingcomputer.com)
An anonymous reader writes: "Following years of criticism and user requests, the FileZilla FTP client is finally adding support for a master password that will act as a key for storing FTP login credentials in an encrypted format," reports BleepingComputer. "This feature is scheduled to arrive in FileZilla 3.26.0, but you can use it now if you download the 3.26.0 (unstable) release candidate from here." By encrypting its saved FTP logins, FileZilla will finally thwart malware that scrapes the sitemanager.xml file and steals FTP credentials, which were previously stolen in plain text. The move is extremely surprising, at least for the FileZilla user base. Users have been requesting this feature for a decade, since 2007, and they have asked it many and many times since then. All their requests have fallen on deaf ears and met with refusal from FileZilla maintainer, Tim Kosse. In November 2016, a user frustrated with Koose's stance forked the FileZilla FTP client and added support for a master password via a spin-off app called FileZilla Secure. -
New Battery Technology Draws Energy Directly From The Human Body (bleepingcomputer.com)
An anonymous reader quotes BleepingComputer: A team of eleven scientists from UCLA and the University of Connecticut has created a new energy-storing device that can draw electrical power from the human body. What researchers created is a biological supercapacitor, a protein-based battery-like device that extracts energy from the human body and then releases it inside an electrical circuit â" the implantable medical device. According to a research paper published earlier this month, the supercapacitor is made up by a device called a "harvester" that operates by using the body's heat and movements to extract electrical charges from ions found in human body fluids, such as blood, serum, or urine.
As electrodes, the harvester uses a carbon nanomaterial called graphene, layered with modified human proteins. The electrodes collect energy from the human body, relay it to the harvester, which then stores it for later use. Because graphene sheets can be drawn in sheets as thin as a few atoms, this allows for the creation of utra-thin supercapacitors that could be used as alternatives to classic batteries. For example, the bio-friendly supercapacitors researchers created are thinner than a human hair, and are also flexible, moving and twisting with the human body. -
New SMB Worm Uses Seven NSA Hacking Tools. WannaCry Used Just Two (bleepingcomputer.com)
An anonymous reader writes: Researchers have detected a new worm that is spreading via SMB, but unlike the worm component of the WannaCry ransomware, this one is using seven NSA tools instead of two. Named EternalRocks, the worm seems to be in a phase where it is infecting victims and building its botnet, but not delivering any malware payload.
EternalRocks is far more complex than WannaCry's SMB worm. For starters, it uses a delayed installation process that waits 24 hours before completing the install, as a way to evade sandbox environments. Further, the worm also uses the exact same filenames as WannaCry in an attempt to fool researchers of its true origin, a reason why the worm has evaded researchers almost all week, despite the attention WannaCry payloads have received.
Last but not least, the worm does not have a killswitch domain, which means the worm can't be stopped unless its author desires so. Because of the way it was designed, it is trivial for the worm's owner to deliver any type of malware to any of the infected computers. Unfortunately, because of the way he used the DOUBLEPULSAR implant, one of the seven NSA hacking tools, other attackers can hijack its botnet and deliver their own malware as well. IOCs are available in a GitHub repo.
Ars Technica quotes security researchers who say "there are at least three different groups that have been leveraging the NSA exploit to infect enterprise networks since late April... These attacks demonstrate that many endpoints may still be compromised despite having installed the latest security patch." -
CIA Co-Developed 'Athena' Windows Malware With US Cyber Security Company, WikiLeaks Reveals (bleepingcomputer.com)
An anonymous reader writes: Today, WikiLeaks leaked documentation about a tool called Athena. According to leaked documents, which WikiLeaks previously claimed it received from hackers and CIA insiders, Athena is an implant -- a CIA technical term for "malware" -- that can target and infect any Windows system, from Windows XP to Windows 10, Microsoft's latest OS version. Documents leaked today are dated between September 2015 and February 2016, showing that the CIA had the ability to hack Windows 10 months after its launch, despite Microsoft boasting about how hard it would be to hack its new OS. [...] The documents reveal that CIA had received help from a non-government contractor in developing the malware. The company is Siege Technologies, a cyber-security company based in New Hampshire, which was acquired on November 15, 2016, by Nehemiah Security, another US company, based in Tysons, Virginia, on the outskirts of Washington and near CIA's headquarters, in a zone peppered with various military and defense contractors. -
Firefox 55: Flash Will Become 'Ask To Activate' For Everyone (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: Starting with the release of Firefox 55, the Adobe Flash plugin for Firefox will be set to "Ask to Activate" by default for all users. This move was announced in August 2016, as part of Mozilla's plan to move away from plugins built around the NPAPI technology. Flash is currently the only NPAPI plugin still supported in Firefox, and moving its default setting from "Always Activate" to "Ask to Activate" is just another step towards the final step of stop supporting Flash altogether. This new Flash default setting is already live in Firefox's Nightly Edition and will move through the Alpha and Beta versions as Firefox nears its v55 Stable release. By moving Flash to a click-to-play setting, Firefox will indirectly start to favor HTML5 content over Flash for all multimedia content. Other browsers like Google Chrome, Brave, or Opera already run Flash on a click-to-play setting, or disabled by default. Firefox is scheduled to be released on August 8, 2017. -
WikiLeaks Dump Reveals CIA Malware That Can Sabotage User Software (bleepingcomputer.com)
An anonymous reader writes: "While the world was busy dealing with the WannaCry ransomware outbreak, last Friday, about the time when we were first seeing a surge in WannaCry attacks, WikiLeaks dumped new files part of the Vault 7 series," reports BleepingComputer. This time, the organization dumped user manuals for two hacking tools named AfterMidnight and Assassin. Both are malware frameworks, but of the two, the most interesting is AfterMidnight -- a backdoor trojan for stealing data from infected PCs. According to its leaked manual, AfterMidnight contains a module to "subvert" user software by killing processes and delaying the execution of user software. Examples in this manual show CIA operatives how to kill browsers every 30 seconds to keep targets focused on their work, how to delay the execution of PowerPoint software with 30 seconds just to mess with their targets, or how to lock up 50% of PC resources whenever the user starts certain software. Basically, the CIA created nagware. -
PCs Connected To the Internet Will Get Infected With WanaDecrypt0r In Minutes (bleepingcomputer.com)
An anonymous reader writes: "The Wana Decrypt0r ransomware -- also known as WCry, WannaCry, WannaCrypt, and WanaCrypt0r -- infected a honeypot server made to look like a vulnerable Windows computer six times in the span of 90 minutes, according to an experiment carried out by a French security researcher that goes online by the name of Benkow," reports BleepingComputer. "During one of those infections, Wana Decrypt0r infected the honeypot in a mere three minutes after it was reset, showing the aggressive nature of the ransomware's scanning module, which helps it spread to new victims... Three minutes is about the same amount of time IoT malware will infect a vulnerable home router left connected to the Internet without patches."
The article also highlights the fact that the group behind this threat is possibly made of inexperienced coders, who just stumbled upon a way to weaponize an NSA exploit. Their three previous WanaDecrypt0r campaigns were mundane, and one researcher called their code "utter [expletive]." This is because WanaDecrypt0r is actually made of two main modules, the ransomware itself, and the SMB worm (based on the NSA exploit). While the SMB worm is top-shelf code, the ransomware itself is quite unsophisticated, making a lot of operational errors, including using only 3 Bitcoin wallets to handle payments, instead of one per infected user, as most top-shelf ransomware does. This makes it difficult to tell which victims paid and who didn't, as anyone could claim "x" transaction is theirs, even if they didn't pay. -
As World Reacts To WanaDecrypt0r, Microsoft Issues Patch For Old Windows Systems (bleepingcomputer.com)
An anonymous reader quotes the AP: Teams of technicians worked "round the clock" Saturday to restore hospital computer systems in Britain and check bank or transport services in other nations after a global cyberattack hit dozens of countries and crippled the U.K.'s health system. The worldwide attack was so unprecedented that Microsoft quickly changed its policy and announced that it will make security fixes available for free for older Windows systems, which are still used by millions of individuals and smaller businesses. [Windows XP, Windows 8, and Windows Server 2003]
An anonymous reader writes: The patches are available for download from here. Microsoft also advises companies and users to disable the Windows Server Message Block version 1 protocol, as it's an old and outdated protocol, already superseded by newer versions, such as SMBv2 and SMBv3... Microsoft had released a fix for that exploit a month before, in March, in security bulletin MS17-010 [which] included fixes for Windows Vista, Windows 7, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2012, and Windows Server 2016.
Below the fold are more stories about the WanaDecrypt0r ransomware.
- The Los Angeles Times says the attack "shows why Apple refused to hack terrorist's iPhone," and why Google, Apple, and Microsoft resist calls for backdoors. "Though the NSA hasn't confirmed it was hacked, the purported leak of its tools shows that even supposedly secret vulnerabilities can get into the wrong hands.... when flaws the agencies discover pose a threat to the nation's businesses and consumers, they should be forced to help secure systems."
- Science fiction writer Charlie Stross blogged a humorous take on the event, sharing a "Rejection Letter" from Reality Publishing Corporation that argues the plot of his newest thriller -- MS17-010 -- "does not hold up to scrutiny." (A government agency hoards known vulnerabilities about vital infrastructure, then suddenly loses control of them...)
- troublemaker_23 shares ITWire's call for a "public statement of contrition" from Microsoft, which reminds readers that "the ransomware and exploits are just the effects. The vulnerabilities in Windows are the cause."
- There's now a first-person account about the discovery of the kill switch, which insists that registering that domain "was not a whim. My job is to look for ways we can track and potentially stop botnets..."
- Slashdot reader Lauren Weinstein says some antivirus services (and firewalls incorporating their rules) are mistakenly blocking the kill switch's site as a 'bad domain', which allows the malware to continue spreading. "Your systems MUST be able to access the domain above if this malware blocking trigger is to be effective, according to the current reports that I'm receiving!"

Wana Decryptor Ransomware Using NSA Exploit Leaked By Shadow Brokers To Spread Ransomware Worldwide (threatpost.com)
msm1267 quotes a report from Threatpost: A ransomware attack running rampant through Europe today is spreading via an exploit leaked in the most recent Shadow Brokers dump. Researchers said the attackers behind today's outbreak of WannaCry ransomware are using EternalBlue, an exploit made public by the mysterious group in possession of offensive hacking tools allegedly developed by the NSA. Most of the attacks are concentrated in Russia, but machines in 74 countries have been infected; researchers at Kaspersky Lab said they've recorded more than 45,000 infections so far on their sensors, and expect that number to climb. Sixteen National Health Service (NHS) organizations in the U.K., several large telecommunications companies and utilities in Spain, and other business throughout Europe have been infected. Critical services are being interrupted at hospitals across England, and in other locations, businesses are shutting down IT systems. An anonymous Slashdot reader adds: Ransomware scum are using an SMB exploit leaked by the Shadow Brokers last month to fuel a massive ransomware outbreak that exploded online today, making victims all over the world in huge numbers. The ransomware's name is Wana Decrypt0r, but is also referenced online under various names, such as WannaCry, WannaCrypt0r, WannaCrypt, or WCry. The ransomware is using the ETERNALBLUE exploit, which uses a vulnerability in the SMBv1 protocol to infect vulnerable computers left exposed online. Microsoft issued a patch for this vulnerability last March, but there are already 36,000 Wana Decrypt0r victims all over the globe, due to the fact they failed to install it. Until now, the ransomware has laid waste to many Spanish companies, healthcare organizations in the UK, Chinese universities, and Russian government agencies. According to security researchers, the scale of this ransomware outbreak is massive and never-before-seen.
UPDATE: The Guardian reports that "An 'accidental hero' has halted the global spread of the WannaCry ransomware" by discovering a kill switch involving "a very long nonsensical domain name that the malware makes a request to." By registering that domain, the spread of the ransomware was effectively halted. -

Cyberattack Hits England's National Health Service With Ransom Demands (theguardian.com)
Hospitals across England have been hit by a large-scale cyber-attack, the NHS has confirmed, which has locked staff out of their computers and forced many trusts to divert emergency patients. The IT systems of NHS sites across the country appear to have been simultaneously hit, with a pop-up message demanding a ransom in exchange for access to the PCs. NHS Digital said it was aware of the problem and would release more details soon. Details of patient records and appointment schedules, as well as internal phone lines and emails, have all been rendered inaccessible. From a report: "The investigation is at an early stage but we believe the malware variant is Wanna Decryptor. At this stage we do not have any evidence that patient data has been accessed. We will continue to work with affected organisations to confirm this. NHS Digital is working closely with the National Cyber Security Centre, the Department of Health and NHS England to support affected organisations and to recommend appropriate mitigations. "This attack was not specifically targeted at the NHS and is affecting organisations from across a range of sectors. "Our focus is on supporting organisations to manage the incident swiftly and decisively, but we will continue to communicate with NHS colleagues and will share more information as it becomes available." NPR adds: The problem erupted around 12:30 p.m. local time, the IT worker says, with a number of email servers crashing. Other services soon went down -- and then, the unidentified NHS worker says, "A bitcoin virus pop-up message had been introduced on to the network asking users to pay $300 to be able to access their PCs. You cannot get past this screen." The attack was not specifically targeted at the NHS and is affecting organizations from across a range of sectors, it appears. The report adds: Images that were posted online of the NHS pop-up look nearly identical to pop-up ransomware windows that hit Spain's Telefonica, a powerful attack that forced the large telecom to order employees to disconnect their computers from its network -- resorting to an intercom system to relay messages. Telefonica, Spain's largest ISP, has told its employees to shut down their computers.
Update: BBC is reporting that similar attacks are being reported in the UK, US, China, Russia, Spain, Italy, Vietnam, Taiwan today. -
Keylogger Found in Audio Driver of HP Laptops, Says Report (bleepingcomputer.com)
An anonymous reader writes: The audio driver installed on some HP laptops includes a feature that could best be described as a keylogger, which records all the user's keystrokes and saves the information to a local file, accessible to anyone or any third-party software or malware that knows where to look. Swiss cyber-security firm modzero discovered the keylogger on April 28 and made its findings public today. According to researchers, the keylogger feature was discovered in the Conexant HD Audio Driver Package version 1.0.0.46 and earlier. This is an audio driver that is preinstalled on HP laptops. One of the files of this audio driver is MicTray64.exe (C:\windows\system32\mictray64.exe). This file is registered to start via a Scheduled Task every time the user logs into his computer. According to modzero researchers, the file "monitors all keystrokes made by the user to capture and react to functions such as microphone mute/unmute keys/hotkeys." -
Call Center Operator and His Cousin Steal $645,000 From UK Water Supplier (bleepingcomputer.com)
An anonymous reader writes: "An unnamed UK-based regional water supply company lost over $645,000 in a sophisticated scam that involved social engineering, an inside man, and international bank transfers," reports BleepingComputer. According to a recently disclosed report, one of the water supplier's call center operators was taking screenshots of customer details and sending this data to his cousin in the UK. This person would trick other call center operators to reset the passwords for those accounts, add his bank account info to the account, and request a refund for previous transactions. Their operation was discovered after customers, usually small-to-medium businesses, discovered they couldn't access their accounts anymore, and also reported new bank account details. A search of the CRM logs revealed that only one call center operator had accessed those profiles, albeit he never initiated or approved refunds. When questioned, the arrogant employee signed an affidavit allowing investigators to search his home PC, thinking they would never discover anything, since he already wiped his hard drive. They did because he forgot to delete his shadow volume copies, where investigators discovered copies of emails sent to his cousin in the UK. These emails contained the screenshots of his work PC with SMB client data. In the end, the call center employee ended up helping authorities secure a conviction for his cousin. -
ISPs Could Take Down Large Parts of Bitcoin Ecosystem If They Wanted To (bleepingcomputer.com)
An anonymous reader writes: A rogue ISP could take down large parts of the Bitcoin ecosystem, according to new research that will be presented in two weeks at the 38th IEEE Symposium on Security and Privacy in San Jose, USA. According to the researchers, there are two types of attack scenarios that could be leveraged via BGP hijacks to cripple the Bitcoin ecosystem: hijacking mining proceeds, causing double-spending errors, and delaying transactions. These two (partition and delay) attacks are possible because most of the entire Bitcoin ecosystem isn't as decentralized as most people think, and it still runs on a small number of ISPs. For example, 13 ISPs host 30% of the entire Bitcoin network, 39 ISPs host 50% of the whole Bitcoin mining power, and 3 ISPs handle 60% of all Bitcoin traffic. Currently, researchers found that around 100 Bitcoin nodes are the victims of BGP hijacks each month. -
Google Researchers Find Wormable 'Crazy Bad' Windows Exploit (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: Two Google security experts have found a severe remote code execution (RCE) bug in the Windows OS, which they've described as "crazy bad." The two experts are Natalie Silvanovich and Tavis Ormandy, both working for Project Zero, a Google initiative for discovering and helping patch zero-days in third-party software products. The two didn't release in-depth details about the vulnerability, but only posted a few cryptic tweets regarding the issue. Drilled with questions by the Twitter's infosec community, Ormandy later revealed more details: the attacker and the victim don't necessarily need to be on the same LAN; the attack works on a default Windows install, meaning victims don't need to install extra software on their systems to become vulnerable; the attack is wormable (can self-replicate). The tweets came days before Microsoft's May 2017 Patch Tuesday, scheduled tomorrow, May 9. The researchers said a report is coming, alluding the vulnerability might be patched this month, and they'll be free to publish their findings. -
Over 200 Android Apps Are Currently Using Ultrasonic Beacons To Track Users (bleepingcomputer.com)
Catalin Cimpanu, writing for BleepingComputer: A team of researchers from the Brunswick Technical University in Germany has discovered an alarming number of Android apps (234, to be exact) that employ ultrasonic tracking beacons to track users and their nearby environment. Their research paper focused on the technology of ultrasound cross-device tracking (uXDT) that became very popular in the last three years. uXDT is the practice of advertisers hiding ultrasounds in their ads. When the ad plays on a TV or radio, or some ad code runs on a mobile or computer, it emits ultrasounds that are picked up by the microphone of nearby laptops, desktops, tablets or smartphones. SDKs embedded in apps installed on those devices relay the beacon back to the online advertiser, who then knows that the user of TV "x" is also the owner of smartphone "Y" and links their two previous advertising profiles together, creating a broader picture of the user's interests, device portfolio, home, and even family members. -
Security Researcher and Alleged Spam Operator To Square Off In Court In Ugly Lawsuit (bleepingcomputer.com)
An anonymous reader writes: River City Media, the company accused of running a huge spam operation, has filed a lawsuit against the security researcher and the journalist who exposed their activities. In a ludicrous lawsuit complaint, the company claims the security researcher didn't just stumble upon its unprotected Rsync server, but "perpetrated a coordinated, months-long cyberattack," during which it skirted firewall rules to access its server, used a VPN to disguise his identity, deleted critical files, and published his findings to make a name for himself as an elite security researcher. The company claims the researcher accessed Dropbox and HipChat logs, and even its PayPal account, from where it used funds to purchase various domains. The only evidence the company has is that the person who purchased the domains used a ProtonMail email, just like the researcher, who also uses a ProtonMail email. Remind you, this is the same security researcher, Chris Vickery, who discovered a Reuters database of supposed terrorism suspects, national voter databases for various U.S. states and Mexico, and various other companies. -
Hacker Leaks 'Orange Is the New Black' Episodes After Failing To Extort Netflix (bleepingcomputer.com)
An anonymous reader writes: "A hacker (or hacker group) known as The Dark Overlord (TDO) has leaked the first ten episodes of season 5 of the "Orange Is The New Black" show after two failed blackmail attempts, against Larson Studios and Netflix," reports BleepingComputer. The hacker said he stole hundreds of gigabytes of audio files from Larson Studios last December. "TDO claims the studio initially agreed to pay a ransom of 50 Bitcoin ($67,000) by January 31, and the two parties even signed a contract, albeit TDO signed it using the name 'Adolf Hitler.'" This might have been the reason why the company thought this was a joke and didn't pay the ransom as initially agreed.
At this point, the hacker turned from the studio to Netflix, but the company didn't want to pay either. As a warning, the hacker leaked the first episode of season 5, but half a day later, he leaked 9 more. "According to Netflix's website, season 5 is supposed to have 13 episodes and is scheduled for release in June, this year." The hacker also claims he's in possession of shows and movies from other movie studios and television channels, such as FOX, IFC, NAT GEO, and ABC. Some of the titles include "Celebrity Apprentice," "NCIS Los Angeles," "New Girl," and "XXX The return of Xander Cage". -
Open Ports Create Backdoors In Millions of Smartphones (bleepingcomputer.com)
An anonymous reader writes: "Mobile applications that open ports on Android smartphones are opening those devices to remote hacking, claims a team of researchers from the University of Michigan," reports Bleeping Computer. Researchers say they've identified 410 popular mobile apps that open ports on people's smartphones. They claim that an attacker could connect to these ports, which in turn grant access to various phone features, such as photos, contacts, the camera, and more. This access could be leveraged to steal photos, contacts, or execute commands on the target's phone. Researchers recorded various demos to prove their attacks. Of these 410 apps, there were many that had between 10 and 50 million downloads on the official Google Play Store and even an app that came pre-installed on an OEMs smartphones. "Research on the mobile open port problem started after researchers read a Trend Micro report from 2015 about a vulnerability in the Baidu SDK, which opened a port on user devices, providing an attacker with a way to access the phone of a user who installed an app that used the Baidu SDK," reports Bleeping Computer. "That particular vulnerability affected over 100 million smartphones, but Baidu moved quickly to release an update. The paper detailing the team's work is entitled Open Doors for Bob and Mallory: Open Port Usage in Android Apps and Security Implications, and was presented Wednesday, April 26, at the 2nd IEEE European Symposium on Security and Privacy that took place this week in Paris, France." -
Backdoor Could Allow Company To Shut Down 70% of All Bitcoin Mining Operations (bleepingcomputer.com)
An anonymous reader writes: "An anonymous security researcher has published details on a vulnerability named "Antbleed," which the author claims is a remote backdoor affecting Bitcoin mining equipment sold by Bitmain, the largest vendor of crypto-currency mining hardware on the market," reports Bleeping Computer. The backdoor code works by reporting mining equipment details to Bitmain servers, who can reply by instructing the customer's equipment to shut down. Supposedly introduced as a crude DRM to control illegal equipment, the company forgot to tell anyone about it, and even ignored a user who reported it last fall. One of the Bitcoin Core developers claims that if such command would ever be sent, it could potentially brick the customer's device for good. Bitmain is today's most popular seller of Bitcoin mining hardware, and its products account for 70% of the entire Bitcoin mining market. If someone hijack's the domain where this backdoor reports, he could be in the position to shut down Bitcoin mining operations all over the world, which are nothing more than the computations that verify Bitcoin transactions, effectively shutting down the entire Bitcoin ecosystem. Fortunately, there's a way to mitigate the backdoor's actions using local hosts files. -
Hacking Group Is Charging German Companies $275 For 'DDoS Tests' (bleepingcomputer.com)
An anonymous reader writes: "A group calling itself XMR Squad has spent all last week launching DDoS attacks against German businesses and then contacting the same companies to inform them they had to pay $275 for 'testing their DDoS protection systems,' reports Bleeping Computer. Attacks were reported against DHL, Hermes, AldiTalk, Freenet, Snipes.com, the State Bureau of Investigation Lower Saxony, and the website of the state of North Rhine-Westphalia. The attack against DHL Germany was particularly effective as it shut down the company's business customer portal and all APIs, prompting eBay Germany to issue an alert regarding possible issues with packages sent via DHL. While the group advertised on Twitter that their location was in Russia, a German reporter who spoke with the group via telephone said "the caller had a slight accent, but spoke perfect German." Following the attention they got in Germany after the attacks, the group had its website and Twitter account taken down. Many mocked the group for failing to extract any payments from their targets. DDoS extortionists have been particularly active in Germany, among any other countries. Previously, groups named Stealth Ravens and Kadyrovtsy have also extorted German companies, using the same tactics perfected by groups like DD4BC and Armada Collective. -
Wall Street IT Engineer Hacks Employer To See If He'll Be Fired (bleepingcomputer.com)
An anonymous reader writes: A Wall Street engineer was arrested for planting credentials-logging malware on his company's servers. According to an FBI affidavit, the engineer used these credentials to log into fellow employees' accounts. The engineer claims he did so only because he heard rumors of an acquisition and wanted to make sure he wouldn't be let go. In reality, the employee did look at archived email inboxes, but he also stole encryption keys needed to access the protected source code of his employer's trading platform and trading algorithms.
Using his access to the company's Unix network (which he gained after a promotion last year), the employee then rerouted traffic through backup servers in order to avoid the company's traffic monitoring solution and steal the company's source code. The employee was caught after he kept intruding and disconnecting another employee's RDP session. The employee understood someone hacked his account and logged the attacker's unique identifier. Showing his total lack of understanding for how technology, logging and legal investigations work, the employee admitted via email to a fellow employee that he installed malware on the servers and hacked other employees. -
Developer of BrickerBot Malware Claims He Destroyed Over Two Million Devices (bleepingcomputer.com)
An anonymous reader writes: In an interview today, the author of BrickerBot, a malware that bricks IoT and networking devices, claimed he destroyed over 2 million devices, but he never intended to do so in the first place. His intentions were to fight the rising number of IoT botnets that were used to launch DDoS attacks last year, such as Gafgyt and Mirai. He says he created BrickerBot with 84 routines that try to secure devices so they can't be taken over by Mirai and other malware. Nevertheless, he realized that some devices are so badly designed that he could never protect them. He says that for these, he created a "Plan B," which meant deleting the device's storage, effectively bricking the device. His identity was revealed after a reporter received an anonymous tip about a HackForum users claiming he was destroying IoT devices since last November, just after BrickerBot appeared. When contacted, BrickerBot's author revealed that the malware is a personal project which he calls "Internet Chemotherapy" and he's "the doctor" who will kill all the cancerous unsecured IoT devices. -
Ambient Light Sensors Can Be Used To Steal Browser Data (bleepingcomputer.com)
An anonymous reader writes: "Over the past decade, ambient light sensors have become quite common in smartphones, tablets, and laptops, where they are used to detect the level of surrounding light and automatically adjust a screen's intensity to optimize battery consumption... and other stuff," reports Bleeping Computer. "The sensors have become so prevalent, that the World Wide Web Consortium (W3C) has developed a special API that allows websites (through a browser) to interact with a device's ambient light sensors. Browsers such as Chrome and Firefox have already shipped versions of this API with their products." According to two privacy and security experts, Lukasz Olejnik and Artur Janc, malicious web pages can launch attacks using this new API and collect data on users, such as URLs they visited in the past and extract QR codes displayed on the screen. This is possible because the light coming from the screen is picked up by these sensors. Mitigating such attacks is quite easy, as it only requires browser makers and the W3C to adjust the default frequency at which the sensors report their readings. Furthermore, the researcher also recommends that browser makers quantize the result by limiting the precision of the sensor output to only a few values in a preset range. The two researchers filed bug reports with both Chrome and Firefox in the hopes their recommendations will be followed. -
User-Made Patch Lets Owners of Next-Gen CPUs Install Updates On Windows 7 & 8.1 (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: GitHub user Zeffy has created a patch that removes a limitation that Microsoft imposed on users of 7th generation processors, a limit that prevents users from receiving Windows updates if they still use Windows 7 and 8.1. This limitation was delivered through Windows Update KB4012218 (March 2017 Patch Tuesday) and has made many owners of Intel Kaby Lake and AMD Bristol Ridge CPUs very angry last week, as they weren't able to install any Windows updates. Microsoft's move was controversial, but the company did its due diligence, and warned customers of its intention since January 2016, giving users enough time to update to Windows 10, move to a new OS, or downgrade their CPU, if they needed to remain on Windows 7 or 8.1 for various reasons. When the April 2017 Patch Tuesday came around last week, GitHub user Zeffy finally had the chance to test four batch scripts he created in March, after the release of KB4012218. His scripts worked as intended by patching Windows DLL files, skipping the CPU version check, and delivering updates to Windows 7 and 8.1 computers running 7th generation CPUs. -
Former Sysadmin Accused of Planting 'Time Bomb' In Company's Database (bleepingcomputer.com)
An anonymous reader writes: Allegro MicroSystems LLC is suing a former IT employee for sabotaging its database using a "time bomb" that deleted crucial financial data in the first week of the new fiscal year. According to court documents, after resigning from his job, a former sysadmin kept one of two laptops. On January 31, Patel entered the grounds of the Allegro headquarters in Worcester, Massachusetts, just enough to be in range of the factory's Wi-Fi network. Allegro says that Patel used the second business-use laptop to connect to the company's network using the credentials of another employee. While connected to the factory's network on January 31, Allegro claims Patel, who was one of the two people in charge of Oracle programming, uploaded a "time bomb" to the company's Oracle finance module. The code was designed to execute a few months later, on April 1, 2016, the first week of the new fiscal year, and was meant to "copy certain headers or pointers to data into a separate database table and then to purge those headers from the finance module, thereby rendering the data in the module worthless." The company says that "defendant Patel knew that his sabotage of the finance module on the first week of the new fiscal year had the maximum potential to cause Allegro to suffer damages because it would prevent Allegro from completing the prior year's fiscal year-end accounting reconciliation and financial reports." -
Microsoft Edge Beats Chrome By Over Three Hours In New Battery Usage Test (bleepingcomputer.com)
An anonymous reader writes: With the launch of the Windows 10 Creators Update and Edge 40 (EdgeHTML 15), Microsoft has released a new battery usage test that, naturally, trashes the company's competition. This new test shows that Edge uses less power than both Chrome 57 and Firefox 52, and is bound to draw a response from its competition, especially Google, who doesn't like it when Microsoft takes a jab at Chrome's efficiency. The same thing happened last year, in June, when a similar test showcasing Edge's longer battery life was met with responses from both Google and Opera.
The most recent tests were performed for the launch of Windows 10 Creators Update. Two tests were carried out until a laptop's battery gave out. For each browser, a minimum of 16 iterations were recorded per test. The first test measured normal browsing performance and the second ran a looped Vimeo fullscreen video. In the normal browsing performance test, Microsoft claims Edge used 31% less power than Chrome 57, and 44% less power than Firefox 52. In the second test, Edge played a looped Vimeo video in fullscreen for 751 minutes (12:31:08), while Chrome lasted 557 minutes (9:17:03) and Firefox for only 424 minutes (7:04:19). That's a whopping three hours over Chrome, and five hours above Firefox. -
Firefox To Let Users Control Memory Usage (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: Mozilla engineers are working on a new section in the browser's preferences that will let users control the browser's performance. Work on this new section started last Friday when an issue was opened in the Firefox bug tracker. Right now, the Firefox UI team has proposed a basic sketch of the settings section and its controls. Firefox developers are now working to isolate or implement the code needed to control those settings [1, 2, 3]. According to the current version of the planned Performance settings section UI, users will be able to control if they use UI animations (to be added in a future Firefox version), if they use page prefetching (feature to preload links listed on a page), and how many "content" processes Firefox uses (Firefox currently supports two processes [one for the Firefox core and one for content], but this will expand to more starting v54). -
Thousands of Fake Google Maps Listings Redirect Users To Fraudulent Sites (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: Tens of thousands of fake listings are added to Google Maps each month, redirecting users to fraudulent websites selling phony or overpriced services, or are part of some referral scam. Researchers say that 74% of these abusive listings were for local businesses in the U.S. and India, mainly in pockets around certain local hotspots, especially in large metropolitan areas such as New York, Chicago, Houston, or Los Angeles. In most cases, the scheme was simple. A customer in need of a locksmith or electrician would search Google Maps for a local company. If he navigated to the website of a fake business or called its number, a call center operator posing as the business' representative would send over an unaccredited contractor that would charge much more than regular professionals. If a customer's situation were urgent, the contractor would often charge more than the initial agreed upon price. Researchers said that 40.3% of all the listings for fake companies they found focused on on-call services, such as locksmiths, plumbers, and electricians, and were for customers who were desperate to resolve issues. Further, overall, operators of fake listings managed to hijack 0.5% of Google Maps' outbound traffic for the studied period. -
Server Snafu Exposes Ask.com User Search Queries Via Internal Status Page (bleepingcomputer.com)
"The Ask.com search engine went through some sort of technical issue late Friday night, as its servers were exposing the internal Apache server status page, revealing recently processed search queries," reports BleepingComputer. An anonymous reader writes: The issue is now fixed, but a copy of the server status page with some search queries can still be viewed in Google's search engine cache. "Some of the weirdest search queries were collected by users in a Hacker News thread," reports BleepingComputer, adding "As you'd expect, the server page included plenty of searches for porn."
The issue also affected localized Ask.com servers, such as uk.ask.com/server-status, us.ask.com/server-status, and de.ask.com/server-status, but no user data was exposed, as the search queries passed through load balancers and already hid user IPs. -
New Destructive Malware Intentionally Bricks IoT Devices (bleepingcomputer.com)
An anonymous reader writes: "A new malware strain called BrickerBot is intentionally bricking Internet of Things (IoT) devices around the world by corrupting their flash storage capability and reconfiguring kernel parameters. The malware spreads by launching brute-force attacks on IoT (BusyBox-based) devices with open Telnet ports. After BrickerBot attacks, device owners often have to reinstall the device's firmware, or in some cases, replace the device entirely. Attacks started on March 20, and two versions have been seen. One malware strain launches attacks from hijacked Ubiquiti devices, while the second, more advanced, is hidden behind Tor exit nodes. Several security researchers believe this is the work of an internet vigilante fed up with the amount of insecure IoT devices connected to the internet and used for DDoS attacks. "Wow. That's pretty nasty," said Cybereason security researcher Amit Serper after Bleeping Computer showed him Radware's security alert. "They're just bricking it for the sake of bricking it. [They're] deliberately destroying the device." -
The Windows 10 Creators Update Is Now Available (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: Microsoft will officially release Windows 10 Creators Update on April 11, the same day it will retire Windows Vista, but users unwilling to wait that long can install it starting today, April 5, using the Windows 10 Update Assistant. The tool installs Build 15063 of the Windows 10 Insiders Build program, which is set to become the official Windows 10 Creators Update next week. The Windows 10 Update Assistant, which Microsoft first launched to help users update to Windows 10, has been recently used to upgrade users to the most recent version of Windows 10. The tool is available for download via the Microsoft site, albeit some users reported still getting an older version for download, which doesn't install the Creators Update. The Update Assistant is extremely easy to use and only requires users to click a few buttons. -
Gigabyte Firmware Bugs Allow the Installation of BIOS/UEFI Ransomware (bleepingcomputer.com)
An anonymous reader writes from a report via BleepingComputer: Last week, at the BlackHat Asia 2017 security conference, researchers from cyber-security firm Cylance disclosed two vulnerabilities in the firmware of Gigabyte BRIX small computing devices, which allow an attacker to write malicious content to the UEFI firmware. During their presentation, researchers installed a proof-of-concept UEFI ransomware, preventing the BRIX devices from booting, but researchers say the same flaws can be used to plant rootkits that allow attackers to persist malware for years. The two vulnerabilities discovered are CVE-2017-3197 and CVE-2017-3198. The first is a failure on Gigabyte's part to implement write protection for its UEFI firmware. The second vulnerability is another lapse on Gigabyte's side, who forgot to implement a system that cryptographically signs UEFI firmware files. Add to this the fact that Gigabyte uses an insecure firmware update process, which doesn't check the validity of downloaded files using a checksum and uses HTTP instead of HTTPS. A CERT vulnerability note was published to warn users of the impending danger and the bugs' ease of exploitation. -
Tor Browser Will Feature More Rust Code (bleepingcomputer.com)
An anonymous reader writes: "The Tor Browser, a heavily modified version of the Firefox browser with many privacy-enhancing features, will include more code written in the Rust programming language," reports BleepingComputer. In a meeting held last week in Amsterdam, Tor developers decided to slowly start using Rust to replace the C++ code. The decision comes after Mozilla started shipping Rust components with Firefox in 2016. Furthermore, Rust is a memory-safe(r) language than C++, the language used for Firefox and the customized Tor code, which means less memory corruption errors. Less of these errors means better privacy for all.
"Part of our interest in using safer languages like Rust in Tor is because a tiny mistake in C could have real consequences for real people," Tor developer Isis Agora Lovecruft posted on Twitter, adding "Also the barrier to entry for contributing to large OSS projects written in C is insanely high." -
Flatbed Scanners Used As Relay Point For Controlling Malware (bleepingcomputer.com)
An anonymous reader writes: "Scientists from two Israeli universities have come up with a way to use flatbed scanners as relay points when sending commands to malware installed on an air-gapped computer," reports BleepingComputer. "Further research also revealed the scanner could also be used to relay stolen data to a nearby attacker. The technique they came up with revolves around the idea that a beam of light could be interpreted as a binary 1 and the lack of visual stimulant can be considered a binary 0."
The attacks can be carried out with lasers mounted on drones, on fixed stands, or by hacking smart light bulbs present near the targeted computer. Attack distances can go up to 900 meters (0.56 miles). During their tests, researchers sent various commands to the PC, such as "d x.pdf" (delete file x.pdf) and "en q" (encrypt folder q). Relaying such commands took between 50 to 100 milliseconds. This research was done by the same team that created methods to steal data from PCs using a hard drive's LED, fan heat, sounds emanated by a computer's GPU fan, electromagnetic signals given out by the GPU, and electromagnetic signals given out by an USB bus.
Here's a PDF of the report, which is titled "Oops!...I think I scanned a malware." -
USB Canary Sends An SMS When Someone Tinkers With Your USB Ports (bleepingcomputer.com)
An anonymous reader quotes a report from BleepingComputer: A new tool released on GitHub last week can help paranoid sysadmins keep track of whenever someone plugs in or disconnects an USB-based device from high-value workstations. Called USB Canary, this tool is coded in Python and currently, works only on Linux (versions for Windows and Mac are in the works). The tool works by watching USB ports for any activity while the computer is locked, which generally means the owner has left his desk. If an USB device is plugged in or unplugged, USB Canary can perform one of two actions, or both. It can alert the owner by sending an SMS message via the Twilio API, or it can post a message in a Slack channel, which can be monitored by other co-workers. USB Canary can prove to be a very useful tool for large organizations that feature strict PC policies. For example, if you really want to enforce a "No USB drives" at work, this could be the tool for the job. Further, with modifications, it could be used for logging USB activity on air-gapped systems. -
Google Plans To Alter JavaScript Popups After Abuse From Tech Support Scammers (bleepingcomputer.com)
An anonymous reader writes: Chromium engineers are discussing plans to change how JavaScript popups work inside Chrome and other similar browsers. In a proposal published on the Google Developers portal, the Chromium team acknowledged that JavaScript popups are consistently used to harm users.
To combat this threat, Google engineers say they plan to make JavaScript modals, like the alert(), confirm(), and dialog() methods, only work on a per-tab basis, and not per-window. This change means that popups won't block users from switching and closing the tab, putting an end to any overly-aggresive tactics on the part of the website's owner(s).
There is no timeline on Google's decision to move JavaScript popups to a per-tab model, but Chromium engineers have been debating this issue since July 2016 as part of Project OldSpice. A similar change was made to Safari 9.1, released this week. Apple's decision came after crooks used a bug in Safari to block users on malicious pages using popups. Crooks then tried to extort payment, posing as ransomware. -
About 90% of Smart TVs Vulnerable To Remote Hacking Via Rogue TV Signals (bleepingcomputer.com)
An anonymous reader quotes a report from Bleeping Computer: A new attack on smart TVs allows a malicious actor to take over devices using rogue DVB-T (Digital Video Broadcasting -- Terrestrial) signals, get root access on the smart TV, and use the device for all sorts of nasty actions, ranging from DDoS attacks to spying on end users. The attack, developed by Rafael Scheel, a security researcher working for Swiss cyber security consulting company Oneconsult, is unique and much more dangerous than previous smart TV hacks. Scheel's method, which he recently presented at a security conference, is different because the attacker can execute it from a remote location, without user interaction, and runs in the TV's background processes, meaning users won't notice when an attacker compromises their TVs. The researcher told Bleeping Computer via email that he developed this technique without knowing about the CIA's Weeping Angel toolkit, which makes his work even more impressing. Furthermore, Scheel says that "about 90% of the TVs sold in the last years are potential victims of similar attacks," highlighting a major flaw in the infrastructure surrounding smart TVs all over the globe. At the center of Scheel's attack is Hybrid Broadcast Broadband TV (HbbTV), an industry standard supported by most cable providers and smart TV makers that "harmonizes" classic broadcast, IPTV, and broadband delivery systems. TV transmission signal technologies like DVB-T, DVB-C, or IPTV all support HbbTV. Scheel says that anyone can set up a custom DVB-T transmitter with equipment priced between $50-$150, and start broadcasting a DVB-T signal. -
Over 14K 'Let's Encrypt' SSL Certificates Issued To PayPal Phishing Sites (bleepingcomputer.com)
BleepingComputer reports: During the past year, Let's Encrypt has issued a total of 15,270 SSL certificates that contained the word 'PayPal' in the domain name or the certificate identity. Of these, approximately 14,766 (96.7%) were issued for domains that hosted phishing sites, according to an analysis carried out on a small sample of 1,000 domains, by Vincent Lynch, encryption expert for The SSL Store... Lynch, who points out the abuse of Let's Encrypt's infrastructure, doesn't blame the Certificate Authority (CA), but nevertheless, points out that other CAs have issued a combined number of 461 SSL certificates containing the term "PayPal" in the certificate information, which were later used for phishing attacks... Phishers don't target these CAs because they're commercial services, but also because they know these organizations will refuse to issue certificates for certain hot terms, like "PayPal," for example. Back in 2015, Let's Encrypt made it clear in a blog post it doesn't intend to become the Internet's HTTPS watchdog.
Of course, some web browsers don't even check whether a certificate has been revoked. An anonymous reader writes: Browser makers are also to blame, along with "security experts" who tell people HTTPS is "secure," when they should point out HTTPS means "encrypted communication channel," and not necessarily that the destination website is secure. -
Anti-Virus Vendors Scramble To Patch Hijacking Exploit Involving Microsoft Tool (securityweek.com)
"A zero-day attack called Double Agent can take over antivirus software on Windows machines," Network World reported Wednesday. wiredmikey writes: The attack involves the Microsoft Application Verifier, a runtime verification tool for unmanaged code that helps developers find subtle programming errors in their applications... [The exploit] allows a piece of malware executed by a privileged user to register a malicious DLL for a process associated with an antivirus or other endpoint security product, and hijack its agent.
Patches were released by Malwarebytes, AVG, and Trend Micro, the security researchers told BleepingComputer earlier this week. Kaspersky Lab told ZDNet "that measures to detect and block the malicious scenario have now been added to all its products," while Norton downplayed the exploit, saying the attack "would require physical access to the machine and admin privileges to be successful," with their spokesperson "adding that it has deployed additional detection and blocking protections in the unlikely event users are targeted."
BetaNews reports that the researchers "say that it is very easy for antivirus producers to implement a method of protection against this zero-day, but it is simply not being done. 'Microsoft has provided a new design concept for antivirus vendors called Protected Processes...specially designed for antivirus services...the protected process infrastructure only allows trusted, signed code to load and has built-in defense against code injection attacks.'" -
Google Reducing Trust In Symantec Certificates Following Numerous Slip-Ups (bleepingcomputer.com)
An anonymous Slashdot reader writes from a report via BleepingComputer: Google Chrome engineers announced plans to gradually remove trust in old Symantec SSL certificates and intent to reduce the accepted validity period of newly issued Symantec certificates, following repeated slip-ups on the part of Symantec. Google's decision comes after the conclusion of an investigation that started on January 19, which unearthed several problems with Symantec's certificate issuance process, such as 30,000 misused certificates. In September 2015, Google also discovered that Symantec issued SSL certificates for Google.com without authorization. Symantec blamed the incident on three rogue employees, whom it later fired. This move from Google will force all owners of older Symantec certificates to request a new one. Google hopes that by that point, Symantec would have revamped its infrastructure and will be following the rules agreed upon by all the other CAs and browser makers. -
LastPass Bugs Allow Malicious Websites To Steal Passwords (bleepingcomputer.com)
Earlier this month, a Slashdot reader asked fellow Slashdotters what they recommended regarding the use of password managers. In their post, they voiced their uncertainty with password managers as they have been hacked in the past, citing an incident in early 2016 where LastPass was hacked due to a bug that allowed users to extract passwords stored in the autofill feature. Flash forward to present time and we now have news that three separate bugs "would have allowed a third-party to extract passwords from users visiting a malicious website." An anonymous Slashdot reader writes via BleepingComputer: LastPass patched three bugs that affected the Chrome and Firefox browser extensions, which if exploited, would have allowed a third-party to extract passwords from users visiting a malicious website. All bugs were reported by Google security researcher Tavis Ormandy, and all allowed the theft of user credentials, one bug affecting the LastPass Chrome extension, while two impacted the LastPass Firefox extension [1, 2]. The exploitation vector was malicious JavaScript code that could be very well hidden in any online website, owned by the attacker or via a compromised legitimate site. -
Google Contemplating Removing Chrome 'Close Other Tabs' and 'Close Tabs to the Right' Options (bleepingcomputer.com)
An anonymous reader shares a report: Chrome engineers are planning to remove two options from Chrome that allow users to quickly close a large number of tabs with just a few clicks. The options, named "Close other tabs" and "Close tabs to the right" reside in the menu that appears when a user right-clicks on a Chrome tab. According to an issue on the Chromium project spotted yesterday by a Reddit user, Google engineers planned to remove to menu options for many years even before opening the Chromium issue, dated itself to July 31, 2015. After several years of inactivity and no decision, things started to move again in September 2016, when usage statistics confirmed that Chrome users rarely used the two options they initially wanted to remove. Seeing no new discussions past this point, Chromium engineers assigned the issue in February, meaning engineers are getting ready to remove the two menu options it in future Chromium builds.
