Security firms have been warning us for more than a year about the possibility of Android malware jumping from phones and tablets to other Android-powered devices, such smart TVs. The latest incident involving ransomware on a smart TV involves software engineer Darren Cauthon, who revealed that the LG smart TV of one of his family members was infected with ransomware right on Christmas day. What's worse? He claims LG wouldn't help him with perform factory reset of the device. From a report: Based on a screenshot Cauthon posted online, the smart TV appears to be infected with a version of the Cyber. Police ransomware, also known as FLocker, Frantic Locker, or Dogspectus. The infected TV is one of the last generations of LG smart TVs that ran Google TV, a smart TV platform developed by Google together with Intel, Sony, and Logitech. Google TV launched in 2010, but Google discontinued the project in June 2014. In the meantime, LG has moved on from Google TV, and the company's TVs now run WebOS. Cauthon says he tried to reset the TV to factory settings, but the reset procedure available online didn't work. When the software engineer contacted LG, the company told him to visit one of their service centers, where one of its employees could reset his TV.

An anonymous reader writes from a report via BleepingComputer: A security flaw discovered in a common PHP class allows knowledgeable attackers to execute code on a website that uses a vulnerable version of the script, which in turn can allow an attacker to take control over the underlying server. The vulnerable library is PHPMailer, a PHP script that allows developers to automate the task of sending emails using PHP code, also included with WordPress, Drupal, Joomla, and more. The vulnerability was fixed on Christmas with the release of PHPMailer version 5.2.18. Nevertheless, despite the presence of a patched version, it will take some time for the security update to propagate. Judging by past incidents, millions of sites will never be updated, leaving a large chunk of the Internet open to attacks. Even though the security researcher who discovered the flaw didn't publish any in-depth details about his findings, someone reverse-engineered the PHPMailer patch and published their own exploit code online, allowing others to automate attacks using this flaw, which is largely still unpatched due to the holiday season.

An anonymous reader writes: Last week, WordPress security firm WordFence revealed it detected over 1.65 million brute-force attacks originating from an ISP in Ukraine that generated more malicious traffic than GoDaddy, OVH, and Rostelecom, put together. A week later, after news of WordFence's findings came to light, Ukrainian users have tracked down the ISP to a company called SKS-Lugan in the city of Alchevs'k, in an area controlled by pro-Russian forces in eastern Ukraine. All clues point to the fact that the ISP's owners are using the chaos created by the Russian military intervention in Ukraine to host cyber-crime operations on their servers. Some of the criminal activities the ISP hosts, besides servers for launching brute-force attacks, include command-and-control servers for the Locky ransomware, [email, comment, and forum] spam botnets, illegal streaming sites, DDoS stressers, carding sites, several banking trojans (Vawtrack, Tinba), and infostealers (Pony, Neurevt). UPDATE 12/22/16: The headline and summary have been updated to reflect the fact that Ukraine is fighting a Russian invasion, and is not in a "civil war," as mentioned in the source.

An anonymous reader writes: Adobe released today Flash Player 24 for Linux, after previously abandoning the application without explanation in 2012. The NPAPI architecture of Flash Player for Linux is now on par with Windows and Mac releases on version 24, after spending the last few years stuck at version 11.2 and only receiving small patches and security fixes, but no new features. Today's Flash Player 24 for Linux release comes after Adobe teased its release on August 31, and later released a Beta version (v23) in October. Despite updating Flash Player for Linux to the same version number as its Windows and Mac alternatives, the Linux variant still lags behind on features. While Flash Player 24 includes all the security features included in the Windows and Mac versions, the Linux version doesn't support accelerated GPU 3D acceleration and video DRMs. If users need these features, Adobe says users should use Chrome for Linux, where Google's own port, the Pepper Flash plugin (PPAPI architecture) supports them.

This week the FBI arrested a 26-year-old southern California man for launching a DDoS attack against online chat service Chatango at the end of 2014 and in early 2015 -- part of a new crackdown on the customers of "DDoS-for-hire" services. An anonymous reader writes: Sean Krishanmakoto Sharma, a computer science graduate student at USC, is now facing up to 10 years in prison and/or a fine of up to $250,000. Court documents describe a service called Xtreme Stresser as "basically a Linux botnet DDoS tool," and allege that Sharma rented it for an attack on Chatango, an online chat service. "Sharma is now free on a $100,000 bail," reports Bleeping Computer, adding "As part of his bail release agreement, Sharma is banned from accessing certain sites such as HackForums and tools such as VPNs..."

"Sharma's arrest is part of a bigger operation against DDoS-for-Hire services, called Operation Tarpit," the article points out. "Coordinated by Europol, Operation Tarpit took place between December 5 and December 9, and concluded with the arrest of 34 users of DDoS-for-hire services across the globe, in countries such as Australia, Belgium, France, Hungary, Lithuania, the Netherlands, Norway, Portugal, Romania, Spain, Sweden, the United Kingdom and the United States." It grew out of an earlier investigation into a U.K.-based DDoS-for-hire service which had 400 customers who ultimately launched 603,499 DDoS attacks on 224,548 targets.
Most of the other suspects arrested were under the age of 20.

"Following a failed takedown attempt, changes made to the Mirai malware variant responsible for building one of today's biggest botnets of IoT devices will make it incredibly harder for authorities and security firms to shut it down," reports Bleeping Computer. An anonymous reader writes: Level3 and others" have been very close to taking down one of the biggest Mirai botnets around, the same one that attempted to knock the Internet offline in Liberia, and also hijacked 900,000 routers from German ISP Deutsche Telekom.The botnet narrowly escaped due to the fact that its maintainer, a hacker known as BestBuy, had implemented a domain-generation algorithm to generate random domain names where he hosted his servers.

Currently, to avoid further takedown attempts from similar security firms, BestBuy has started moving the botnet's command and control servers to Tor. "It's all good now. We don't need to pay thousands to ISPs and hosting. All we need is one strong server," the hacker said. "Try to shut down .onion 'domains' over Tor," he boasted, knowing that nobody can.

An anonymous reader writes: Swedish hardware hacker Ulf Frisk has created a device that can extract Mac FileVault2 (Apple's disk encryption utility) passwords from a device's memory before macOS boots and anti-DMA protections kick in. The extracted passwords are in cleartext, and they also double as the macOS logon passwords. The attack requires physical access, but it takes less than 30 seconds to carry out. A special device is needed, which runs custom software (available on GitHub), and uses hardware parts that cost around $300. Apple fixed the attack in macOS 10.12.2. The device is similar to what Samy Kamker created with Poison Tap.

An anonymous reader quotes a report from BleepingComputer: Malicious ads are serving exploit code to infect routers, instead of browsers, in order to insert ads in every site users are visiting. Unlike previous malvertising campaigns that targeted users of old Flash or Internet Explorer versions, this campaign focused on Chrome users, on both desktop and mobile devices. The malicious ads included in this malvertising campaign contain exploit code for 166 router models, which allow attackers to take over the device and insert ads on websites that didn't feature ads, or replace original ads with the attackers' own. Researchers haven't yet managed to determine an exact list of affected router models, but some of the brands targeted by the attackers include Linksys, Netgear, D-Link, Comtrend, Pirelli, and Zyxel. Because the attack is carried out via the user's browser, using strong router passwords or disabling the administration interface is not enough. The only way users can stay safe is if they update their router's firmware to the most recent versions, which most likely includes protection against the vulnerabilities used by this campaign. The "campaign" is called DNSChanger EK and works when attackers buy ads on legitimate websites and insert malicious JavaScript in these ads, "which use a WebRTC request to a Mozilla STUN server to determine the user's local IP address," according to BleepingComputer. "Based on this local IP address, the malicious code can determine if the user is on a local network managed by a small home router, and continue the attack. If this check fails, the attackers just show a random legitimate ad and move on. For the victims the crooks deem valuable, the attack chain continues. These users receive a tainted ad which redirects them to the DNSChanger EK home, where the actual exploitation begins. The next step is for the attackers to send an image file to the user's browser, which contains an AES (encryption algorithm) key embedded inside the photo using the technique of steganography. The malicious ad uses this AES key to decrypt further traffic it receives from the DNSChanger exploit kit. Crooks encrypt their operations to avoid the prying eyes of security researchers."

Microsoft is following in the footsteps of other browser makers such as Apple, Google, and Mozilla, and says that upcoming Edge browser versions will favor HTML5 over Flash by default. From a report on BleepingComputer: "Sites that support HTML5 will default to a clean HTML5 experience," Microsoft said today. "In these cases, Flash will not even be loaded, improving performance, battery life, and security." On sites where Flash is needed, users will be prompted using a popup like the one seen below. Edge will ask users only once, and the browser will remember the user's choice for subsequent visits. Microsoft has already pushed these changes to Edge users on Windows Insiders builds. Regular Windows users will receive this update in the coming weeks.

An anonymous reader writes: Security researchers have found malware hidden in the firmware of several low-end Android smartphones and tablets, malware which is used to show ads and install unwanted apps on the devices of unsuspecting users. 26 Android device models have been found to be vulnerable. The common link between all these devices is that all are low-cost devices, mostly marketed in Russia, and which run on MediaTek chipsets.

According to security researchers from Dr.Web, a Russian antivirus vendor, the malware appears to have been added to the firmware by "dishonest outsourcers who took part in [the] creation of Android system images decided to make money on users." The security firm has informed MediaTek and the device vendors about this issue so the affected companies can inspect their distribution chain and find the possible culprits.

An anonymous reader writes: To protect Tor users from FBI hacking tools that include all sorts of Firefox zero-days, the Tor Project started working on a sandboxed version of the Tor Browser in September. Over the weekend, the Tor Project released the first alpha version of the sandboxed Tor Browser. "Currently, this version is in an early alpha stage, and only available for Linux," reports BleepingComputer. "There are also no binaries available, and users must compile it themselves from the source code, which they can grab from here." The report notes: "Sandboxing is a security mechanism employed to separate running processes. In computer security, sandboxing an application means separating its process from the OS, so vulnerabilities in that app can't be leveraged to extend access to the underlying operating system. This is because the sandboxed application works with its own separate portion of disk and memory that isn't linked with the OS."

MalwareHunterTeam has discovered "Popcorn Time," a new in-development ransomware with a twist. Gumbercules!! writes: "With Popcorn Time, not only can a victim pay a ransom to get their files back, but they can also try to infect two other people and have them pay the ransom in order to get a free key," writes Bleeping Computer. Infected victims are given a "referral code" and, if two people are infected by that code and pay up -- the original victim is given their decryption key (potentially).
While encrypting your files, Popcorn Time displays a fake system screen that says "Downloading and installing. Please wait" -- followed by a seven-day countdown clock for the amount of time left to pay its ransom of one bitcoin. That screen claims that the perpetrators are "a group of computer science students from Syria," and that "all the money that we get goes to food, medicine, shelter to our people. We are extremely sorry that we are forcing you to pay but that's the only way that we can keep living." So what would you do if this ransomware infected your files?

An anonymous reader writes from a report via BleepingComputer: The security protocol that governs how virtual machines share data on a host system powered by AMD Zen processors has been found to be insecure, at least in theory, according to two German researchers. The technology, called Secure Encrypted Virtualization (SEV), is designed to encrypt parts of the memory shared by different virtual machines on cloud servers. AMD, who plans to ship SEV with its upcoming line of Zen processors, has published the technical documentation for the SEV technology this past April. The German researchers have analyzed the design of SEV, using this public documentation, and said they managed to identify three attack channels, which work, at least in theory.

[In a technical paper released over the past weekend, the researchers described their attacks:] "We show how a malicious hypervisor can force the guest to perform arbitrary read and write operations on protected memory. We describe how to completely disable any SEV memory protection configured by the tenant. We implement a replay attack that uses captured login data to gain access to the target system by solely exploiting resource management features of a hypervisor." AMD is scheduled to ship SEV with the Zen processor line in the first quarter of 2017.

An anonymous reader quotes a report from BleepingComputer: For the past two months, a new exploit kit has been serving malicious code hidden in the pixels of banner ads via a malvertising campaign that has been active on several high profile websites. Discovered by security researchers from ESET, this new exploit kit is named Stegano, from the word steganography, which is a technique of hiding content inside other files. In this particular scenario, malvertising campaign operators hid malicious code inside PNG images used for banner ads. The crooks took a PNG image and altered the transparency value of several pixels. They then packed the modified image as an ad, for which they bought ad displays on several high-profile websites. Since a large number of advertising networks allow advertisers to deliver JavaScript code with their ads, the crooks also included JS code that would parse the image, extract the pixel transparency values, and using a mathematical formula, convert those values into a character. Since images have millions of pixels, crooks had all the space they needed to pack malicious code inside a PNG photo. When extracted, this malicious code would redirect the user to an intermediary ULR, called gate, where the host server would filter users. This server would only accept connections from Internet Explorer users. The reason is that the gate would exploit the CVE-2016-0162 vulnerability that allowed the crooks to determine if the connection came from a real user or a reverse analysis system employed by security researchers. Additionally, this IE exploit also allowed the gate server to detect the presence of antivirus software. In this case, the server would drop the connection just to avoid exposing its infrastructure and trigger a warning that would alert both the user and the security firm. If the gate server deemed the target valuable, then it would redirect the user to the final stage, which was the exploit kit itself, hosted on another URL. The Stegano exploit kit would use three Adobe Flash vulnerabilities (CVE-2015-8651, CVE-2016-1019 or CVE-2016-4117) to attack the user's PC, and forcibly download and launch into execution various strains of malware.

An anonymous reader quotes a report from BleepingComputer: Google engineers are working on an improved version of the reCAPTCHA system that uses a computer algorithm to distinguish between automated bots and real humans, and requires no user interaction at all. Called "Invisible reCAPTCHA," and spotted by Windows IT Pro, the service is still under development, but the service is open for sign-ups, and any webmaster can help Google test its upcoming technology. Invisible reCAPTCHA comes two years after Google has revolutionized CAPTCHA technologies by releasing the No CAPTCHA reCAPTCHA service that requires users to click on one checkbox instead of solving complex visual puzzles made up of words and numbers. The service helped reduce the time needed to fill in forms, and maintained the same high-level of spam detection we've become accustomed from the reCAPTCHA service. The introduction of the new Invisible reCAPTCHA technology is unlikely to make the situation better for Tor users since CloudFlare will likely force them to solve the same puzzle if they come from IPs seen in the past performing suspicious actions. Nevertheless, CloudFlare started working on an alternative.

After being let go over a series of "personal issues" with his employer, things got worse for 26-year-old network administrator Dariusz J. Prugar, who will now have to spend two years in prison for hacking the ISP where he'd worked. An anonymous reader writes: Prugar had used his old credentials to log into the ISP's network and "take back" some of the scripts and software he wrote... "Seeking to hide his tracks, Prugar used an automated script that deleted various logs," reports Bleeping Computer. "As a side effect of removing some of these files, the ISP's systems crashed, affecting over 500 businesses and over 5,000 residential customers."

When the former ISP couldn't fix the issue, they asked Prugar to help. "During negotiations, instead of requesting money as payment, Prugar insisted that he'd be paid using the rights to the software and scripts he wrote while at the company, software which was now malfunctioning, a week after he left." This tipped off the company, who detected foul play, contacted the FBI and rebuilt its entire network.
Six years later, Prugar was found guilty after a one-week jury trial, and was ordered by the judge to pay $26,000 in restitution to the ISP (which went out of business in October of 2015). Prugar's two-year prison sentence begins December 27.

An anonymous reader quotes Bleeping Computer: Chrome 55, released earlier this week, now blocks all Adobe Flash content by default, according to a plan set in motion by Google engineers earlier this year... While some of the initial implementation details of the "HTML5 By Default" plan changed since then, Flash has been phased out in favor of HTML5 as the primary technology for playing multimedia content in Chrome.

Google's plan is to turn off Flash and use HTML5 for all sites. Where HTML5 isn't supported, Chrome will prompt users and ask them if they want to run Flash to view multimedia content. The user's option would be remembered for subsequent visits, but there's also an option in the browser's settings section, under Settings > Content Settings > Flash > Manage Exceptions, where users can add the websites they want to allow Flash to run by default.
Exceptions will also be made automatically for your more frequently-visited sites -- which, for many users, will include YouTube. And Chrome will continue to ship with Flash -- as well as an option to re-enable Flash on all sites.

An anonymous reader quotes a report from BleepingComputer: Windows security expert and infrastructure trainer Sami Laiho says that by holding SHIFT + F10 while a Windows 10 computer is installing a new OS build, an attacker can open a command-line interface with SYSTEM privileges. This CLI debugging interface also grants the attacker full access to the computer's hard drive data, despite the presence of BitLocker. The CLI debugging interface is present when updating to new Windows 10 and Windows 10 Insiders builds. The most obvious exploitation scenario is when a user leaves his computer unattended during the update procedure. A malicious insider can open the CLI debugger and perform malicious operations under a root user, despite BitLocker's presence. But there are other scenarios where Laiho's SHIFT + F10 trick can come in handy. For example when police have seized computers from users who deployed BitLocker or when someone steals your laptop. Windows 10 defaults help police/thieves in this case because these defaults forcibly update computers, even if the user hasn't logged on for weeks or months. This CLI debugging interface grants the attacker full access to the computer's hard drive, despite the presence of BitLocker. The reason is that during the Windows 10 update procedure, the OS disables BitLocker while the Windows PE (Preinstallation Environment) installs a new image of the main Windows 10 operating system. "This [update procedure] has a feature for troubleshooting that allows you to press SHIFT + F10 to get a Command Prompt," Laiho writes on his blog. "The real issue here is the Elevation of Privilege that takes a non-admin to SYSTEM (the root of Windows) even on a BitLocker (Microsoft's hard disk encryption) protected machine." Laiho informed Microsoft of the issue and the company is apparently working on a fix.

An anonymous reader writes: Two hackers are renting access to a massive Mirai botnet, which they claim has more than 400,000 infected bots, ready to carry out DDoS attacks at anyone's behest. The hackers have quite a reputation on the hacking underground and have previously been linked to the GovRAT malware, which was used to steal data from several US companies. Renting around 50,000 bots costs between $3,000-$4,000 for 2 weeks, meaning renting the whole thing costs between $20,000-$30,000.

After the Mirai source code leaked, there are countless smaller Mirai botnets around, but this one is [believed to be the one] accounting for more than half of all infected IoT devices...that supposedly shut down Internet access in Liberia. The original Mirai botnet was limited to only 200,000 bots because there were only 200,000 IoT devices connected online that had their Telnet ports open. The botnet that's up for rent now has received improvements and can also spread to IoT devices via SSH, hence the 400,000 bots total.
Interestingly, the article claims the botnet's creators had access \to the Mirai source code "long before it went public."

An anonymous reader writes: By leveraging security flaws in the Tesla Android app, an attacker can steal Tesla cars. The only hard part is tricking Tesla owners into installing an Android app on their phones, which isn't that difficult according to a demo video from Norwegian firm Promon. This malicious app can use many of the freely available Android rooting exploits to take over the user's phone, steal the OAuth token from the Tesla app and the user's login credentials. This is possible because the Tesla Android app stores the OAuth token in cleartext, and contains no reverse-engineering protection, allowing attackers to alter the app's source code and log user credentials. The OAuth token and Tesla owner's password allow an attacker to perform a variety of actions, such as opening the car's doors and starting the motor.

mask.of.sanity quotes a report from The Register: Up to a quarter of all websites on the internet could have been breached through a since-patched vulnerability that allowed WordPress' core update server to be compromised. The since-shuttered remote code execution flaw was found in a php webhook within api.wordpress.org that allows developers to supply a hashing algorithm of their choice to verify code updates are legitimate. Matt Barry, lead developer of WordPress security outfit WordFence, found attackers could supply their own extremely weak hashing algorithm as part of that verification process, allowing a shared secret key to be brute-forced over the course of a couple of hours. The rate of guessing attempts would be small enough to fly under the radar of WordPress' security systems. Attackers that used the exploit could then send URLs to the WordPress update servers that would be accepted and pushed out to all WordPress sites. Web-watching service W3techs.com reckons those sites represent 27.1 per cent of the entire world wide web. "By compromising api.wordpress.org, an attacker could conceivably compromise more than a quarter of the websites worldwide in one stroke," Barry says. "We analyzed [WordPress] code and found a vulnerability that could allow an attacker to execute their own code on api.wordpress.org and gain access to it. Compromising this [update] server could allow an attacker to supply their own URL to download and install software to WordPress websites, automatically." Attackers could go further; once a backdoored or malicious update was pushed out, they could disable the default auto updates preventing WordPress from fixing compromised websites.

An anonymous reader quotes Bleeping Computer: Security researchers have discovered that third-party firmware included with over 2.8 million low-end Android smartphones allows attackers to compromise Over-the-Air (OTA) update operations and execute commands on the target's phone with root privileges. This is the second issue of its kind that came to light this week after researchers from Kryptowire discovered a similar secret backdoor in the firmware of Chinese firm Shanghai Adups Technology Co. Ltd.. This time around, the problem affected Android firmware created by another Chinese company named Ragentek Group.
It apparently affects more than 55 low-end/burner phones from BLU, Infinix Mobility, DOOGEE, LEAGOO, IKU Mobile, Beeline, and XOLO. According to the article, the binary performing the insecure updates "also includes code to hide its presence from the Android OS, along with two other binaries and their processes... Without SSL protection, this OTA system is an open backdoor for anyone looking to take control of it." Even worse, three domains were hard-coded into the binaries, two of which were unregistered, according to the researchers. "If an adversary had noticed this, and registered these two domains, they would've instantly had access to perform arbitrary attacks on almost 3,000,000 devices without the need to perform a Man-in-the-Middle attack."

Bleeping Computer warns that "The way users move fingers across a phone's touchscreen alters the WiFi signals transmitted by a mobile phone, causing interruptions that an attacker can intercept, analyze, and reverse engineer to accurately guess what the user has typed...when the attacker controls a rogue WiFi access point." The new WindTalker attack leverages the "channel state information" in WiFi signals. An anonymous reader quotes their article: Because the user's finger moves across the smartphone when he types text, his hand alters CSI properties for the phone's outgoing WiFi signals, which the attacker can collect and log on the rogue access point... By performing basic signal analysis and signal processing, an attacker can separate desired portions of the CSI signal and guess with an average accuracy of 68.3% the characters a user has typed... but it can be improved the more the user types and the more data the attacker collects.
The new attack is described in a research paper titled "When CSI Meets Public WiFi: Inferring Your Mobile Phone Password via WiFi Signals."

An anonymous reader quotes Bleeping Computer: German police mocked a group of bungling crooks that tried to rob an ATM, but instead of malware they chose explosives, which they unwittingly placed near a device that issued bank statements, and not the actual money-dispensing ATM... The crooks placed small explosive charges next to a machine they thought to be an ATM, in the hopes of breaking its outer casing and getting access to the money vault inside... After being called in to investigate the loud blast that woke up the bank's neighbors German police discovered a partially destroyed bank statement printing machine... No money was stolen in the failed robbery, police reported.
In a statement on the Berlin police department's official web site, they described the ATM thieves as "not very clever."

An anonymous reader writes: "A bug in the iOS WebView component allows an attacker to force someone's iPhone to dial any number, while also locking the user's interface for a few moments, preventing him to cancel the outgoing call," reports BleepingComputer. "The bug was at the heart of the recent accidental DDoS of 911 call centers across the U.S." At the heart of the issue is a Safari bug reported in 2008, which was fixed in iOS 3.0. The same bug also exists in the WebView component used by app makers to show web pages inside other apps. The researcher that found the bug writes in a blog post: "If you think automatically dialing a phone number after clicking a link in an app is not a big issue think again. DoSing 911 is pretty terrible but there are other examples such as expensive 900 numbers where the attacker can actually make money. A stalker can make his victim dial his phone number so he gets his victim's number. Altogether things you don't want to happen. [...] Apple should change the default behavior of WebViews to exclude execution of TEL URIs and make it an explicit feature to avoid this kind of issues in the future."

An anonymous reader writes: "Three days before the US Presidential Election takes place, California-based security firm Cylance showed the world how easy it is to hack one of the many [electronic] voting machine models that will be deployed at voting stations across the US on Election Day." Bleeping Computer reports that "The machine that Cylance researchers chose for their test was the Sequoia AVC Edge Mk1, one of the most popular models... The technique researchers created modifies the Public Counter, but also the Protective Counter, which is a backup mechanism that acts as a redundant verification system to ensure the first vote results are valid." Physical access is needed to hack the machine, but the hack takes a short time to perform.
FBI Director James Comey said in September that America's voting machines would be hard to compromise because they're not connect to the internet, but these researchers simply used a PCMCIA card to reflash the machine's firmware. Comey also made the reassuring point that it's hard to "hack into" America's voting system because "it's so clunky and dispersed. It's Mary and Fred putting a machine under the basketball hoop at the gym."

An anonymous reader quotes Bleeping Computer: "Two researchers presenting at the Black Hat Europe security conference in London revealed a method of infecting industrial equipment with an undetectable rootkit component that can wreak havoc and disrupt the normal operations of critical infrastructure all over the world. The attack targets PLCs (Programmable Logic Controllers), devices that sit between normal computers that run industrial monitoring software and the actual industrial equipment, such as motors, valves, sensors, breakers, alarms, and others."

Researchers say they packed their attack as a loadable kernel module [PDF], which makes it both undetectable and reboot persistent. The attack goes after PLC pin configurations, meaning the PLC won't be able to tell which are the actual input and output pins, allowing the attacker full-control to make up bogus sensor data, send fake commands, or block legitimate ones.
The researchers acknowledge that the attack is extremely complicated, but the article argues it would still be of interest to a state-sponsored actor.

If users don't pay, every hour the ransomware deletes your files. If the user restarts their PC, the ransomware also deletes 1,000 more files. The good news is there's a free Decrypter available to unlock the ransomware. The Decrypter was built by Michael Gillespie, who announced yesterday on Softpedia the ID Ransomware service, which tells infected victims what kind of ransomware infection they have by allowing them to upload an encrypted file and the ransom note.

Reader itwbennett writes: Petya appeared on researchers' radar last month when criminals distributed it to companies through spam emails that masqueraded as job applications. It stood out from other file-encrypting ransomware programs because it overwrites a hard drive's master boot record (MBR), leaving infected computers unable to boot into the operating system. Now, security experts have devised a method that, while not exactly straightforward, allows users to recover data from computers infected with the ransomware without paying money to cyber criminals. Folks over at BleepingComputer have confirmed that the aforementioned technique works.

First, according to cyber intelligence outfit SenseCy, it is available for sale 'as a service' on a private Russian-language forum, which makes it 'available to low-level criminals who might not have the coding skills or resources to create their own ransom ware,' writes Lucian Constantin. Second, one of the 3 files it drops on a victim's desktop is a VBS (Visual Basic Scripting) file containing text-to-speech code that converts text into an audio message. 'When the above script is executed, your computer will speak a message stating that your computer's files were encrypted and will repeat itself numerous times,' said Lawrence Abrams, administrator of the technical support forum BleepingComputer.com, in a blog post.

At issue: a bad review posted by a user in September, 2014. The lawsuit also accuses Bleeping Computer of profiting from driving traffic to competitor Malwarebytes via affiliate links: 'Bleeping has a direct financial interest in driving traffic and sales to Malwarebytes and driving traffic and sales away from ESG.' Perhaps not helping matters, one of the first donations to a fund set up by Bleeping Computer to help with legal costs came from Malwarebytes.

The tool is quite easy to use, and will generate a decryption key. For best results users should compare an encrypted and decrypted file, but the tool can also get the decryption key by comparing an encrypted PNG with a random PNG downloaded off the Internet.

An anonymous reader writes: A new ransomware family was not tested by its developer and is encrypting user files and then throwing away the encryption key because of an error in its programming. The ransomware author wanted to cut down costs by using a static encryption key for all users, but the ransomware kept generating random keys which it did not store anywhere. The only way to recover files is if users had a previous backup. You can detect it by the ransom message which has the same ID:qDgx5Bs8H

itwbennett (1594911) writes "When Jose Vildoza's father became the victim of ransomware, he launched his own investigation. Diving into CryptoDefense's code, he found its developers had made a crucial mistake: CryptoDefense used Microsoft's Data Protection API (application programming interface), a tool in the Windows operating system to encrypt a user's data, which stored a copy of the encryption keys on the affected computer. Vildoza and researcher Fabian Wosar of the Austrian security company Emsisoft collaborated on a utility called the Emsisoft Decrypter that could recover the encrypted keys. In mid-March Vildoza had launched a blog chronicling his investigation, purposely not revealing the mistake CryptoDefense's authors had made. But Symantec then published a blog post on March 31 detailing the error."

Varzil found an interesting story about some "Rogue Anti-Malware" (which seems to me should just be called 'Malware') which modifies your HOSTS file to trick you into reading a fake anti-virus review which is of course for more malware. Modifying HOSTS is an old trick, but this is interesting because it's actually trying to get you to read fake content: normally this sort of trick is used to prevent you from fixing your computer, but this one is trying to get you to break it even more. I guess friends don't let friends modify their HOSTS files.
