Avast Launches Open-Source Decompiler For Machine Code (techspot.com)
Greg Synek reports via TechSpot: To help with the reverse engineering of malware, Avast has released an open-source version of its machine-code decompiler, RetDec, that has been under development for over seven years. RetDec supports a variety of architectures aside from those used on traditional desktops including ARM, PIC32, PowerPC and MIPS. As Internet of Things devices proliferate throughout our homes and inside private businesses, being able to effectively analyze the code running on all of these new devices becomes a necessity to ensure security. In addition to the open-source version found on GitHub, RetDec is also being provided as a web service.
Simply upload a supported executable or machine code and get a reasonably rebuilt version of the source code. It is not possible to retrieve the exact original code of any executable compiled to machine code but obtaining a working or almost working copy of equivalent code can greatly expedite the reverse engineering of software. For any curious developers out there, a REST API is also provided to allow third-party applications to use the decompilation service. A plugin for IDA disassembler is also available for those experienced with decompiling software. -
First Remote-Access Trojan That Can Target Android, Linux, Mac and Windows
An anonymous reader writes: Hackers have put on sale OmniRAT, a remote access trojan that can target Androids, Linux, Mac, and Windows PCs. The tool costs $25-$50, which is only a fraction of $200-$300,the price of DroidJack, another Android RAT. Avast is currently reporting that the RAT was used this summer in Germany, spread to victims via SMS messages. The Softpedia article about OmniRAT includes a video, but declined to post the tool's homepage. You can easily find it via a Google search. -
Windows Phone Store Increasingly Targeted With Fake Mobile Apps
An anonymous reader writes: A post by security company Avast says not only are a large amount of fake apps available from the third-party marketplace of the Windows Phone Store, but they also remain available for quite a while despite negative comments and other flags from end-users. Avast speculates that improved security and auditing procedures at rival stores such as Google Play account for the increasing attention that fake app-publishers are giving to the Windows phone app market. -
Avast Buys 20 Used Phones, Recovers 40,000 Deleted Photos
An anonymous reader writes: The used smartphone market is thriving, with many people selling their old devices on eBay or craigslist when it's time to upgrade. Unfortunately, it seems most people are really bad at wiping their phone of personal data before passing it on to a stranger. Antivirus company Avast bought 20 used Android phones off eBay, and used some basic data recovery software to reconstruct deleted files. From just those 20 phones, they pulled over 40,000 photographs, including 1,500 family pictures of children and over a thousand more.. personal pictures. They also recovered hundreds of emails and text messages, over a thousand Google searches, a completed loan application, and identity information for four of the previous owners. Only one of the phones had security software installed on it, but that phone turned out to provide the most information of all: "Hackers at Avast were able to identify the previous owner, access his Facebook page, plot his previous whereabouts through GPS coordinates, and find the names and numbers of more than a dozen of his closest contacts. What's more, the company discovered a lot about this guy's penchant for kink and a completed copy of a Sexual Harassment course — hopefully a preventative measure." -
FileZilla Has an Evil Twin That Steals FTP Logins
Nerval's Lobster writes "On the same day the world discovered Western intelligence agencies were siphoning user information from Angry Birds and other popular smartphone apps, a leading antivirus developer revealed hackers are doing the same thing with one of the most popular open-source applications on the Internet. Maliciously modified versions of the popular FTP application FileZilla look and act just like the real thing, but include extra code that steals the login data typed in by users and sends it to an unauthorized server using the same FTP operation launched by the user without going through a firewall that might spot what it's doing, according to an alert posted this afternoon by antivirus developer Avast Software. The malicious version is fully functional, uses the same graphical interface and component file names as the original, and masks itself further by avoiding any suspicious entries in the system registry, overt attempts to communicate with outside servers or other changes, according to the Jan. 27 alert from Avast. The most obvious differences are that the poisoned version of filezilla.exe is 6.8MB smaller than the real thing and there are two DLL libraries included in the fake that are not present in the original. They are labeled ibgcc_s_dw2-1.dll and libstdc++-6.dll, according to Avast. The official version's Nullsoft installer is v2.45-Unicode; the evil twin uses v2.46.3-Unicode. Automatic updates also fail on the poisoned version 'which is most likely a protection to prevent overwriting of the malware binaries,' Avast added." -
Avast Drops iYogi Support Over Pushy Scare Tactics
An anonymous reader writes "Antivirus maker Avast is suspending its relationship with iYogi, a company it has relied upon for the past two years to provide live customer support for its products. The move comes just one day after an investigation into iYogi showed the company was using the relationship to push expensive and unnecessary support contracts onto Avast users. In a blog post, Avast's CEO wrote, 'We had initial reports of this behavior a few weeks ago and met with iYogi's senior executives to ensure the behavior was being corrected. Thus, we were shocked to find out about Mr. Krebs' experience. As a consequence, we have removed the iYogi support service from our website and shortly it will be removed from our products.'" -
Best of the Free Anti-virus Choices?
iamjoltman writes "I've been looking to replace the McAfee anti-virus on my parent's XP machine. So, I've been looking at the three free anti-virus choices, AVG Free Edition, avast! Home Edition and AntiVir Personal Edition. I know there are other options, but I believe any others are only on-demand scanners, and that's not an option. So, what does the Slashdot crowd think is the best of these choices? Keep in mind, I'm only looking in anti-virus, I'll go elsewhere for firewall or malware protection."
