The advisory also has instructions on how to remove the malware. HandBrake’s notice includes SHA1 and SHA256 hashes that users can do a checksum on to detect if the file contains the Proton backdoor. To mitigate Proton, HandBrakes’ developers urges its users to check if their version of the application runs “Activity_agent”, which users can verify with the OSX Activity Monitor app. The ever-increasing synergy between various Apple devices and software will only motivate cybercriminals into targeting these platforms more. Apple is projected to outpace Microsoft in terms of vulnerability discoveries. Indeed, attacks on Apple devices and software are no longer considered “unprecedented”. In fact, Trend Micro has observed a steady increase of malware that target Apple users-from black hat search engine optimization attacks, exploits that leverage security flaws in Mac, potentially unwanted applications like adware that can bypass privacy protection, and phishing, to rootkits and even ransomware such as KeRanger (OSX_KERANGER). For instance, Trend Micro observed over 221,000 detections of Mac-based threats in December 2016 alone-a significant surge from November 2016, which were only at 81,000. As Apple-based devices continue to gain traction in market share, so will threats that target them. These threats dispel the notion that Mac-based systems are bulletproof from malware. Like Snake, Proton uses a signed Apple certificate to run in the infected system, allowing it to steal credentials such as those stored in password-storing utilities like Apple’s own Ke圜hain and other browser-based services. Attackers replaced the legitimate HandBrake app with their own malicious file, one that didn’t match the SHA1 or SHA256 hashes in their website or Github repository.
In a security advisory released by HandBrake’s developers in their forums, the compromise occurred between May 2nd (14:30 UTC) and May 6th (11:00 UTC). The Proton backdoor made the rounds after its operators compromised the mirror/alternate download server of HandBrake, a popular, open-source video transcoding application, to deliver the malware.
The debug functions observed in Snake indicate that it’s still in development and is expected to be fully operational soon.

This iteration of Snake uses a valid-most likely stolen-Apple developer certificate to bypass Gatekeeper’s (a security feature of Mac OS X systems) code signing restriction and permit it to be executed in the system.

This time, they’ve ported the Windows version of the backdoor for Mac OS X systems, using a poisoned, zipped Adobe Flash Player installer as a lure. Its rootkit capabilities allowed it to maintain persistence in the infected system by hiding its malicious processes and files from the user, which in turn made detection challenging. Snake slithered its way into its targets by exploiting an array of vulnerabilities. In 2014, its operators created a version that worked on Linux machines.
Snake originally targeted Windows OS-based systems as early as 2008, and was used for cyberespionage. Both are remote access Trojans that can grant attackers unauthorized remote access to the system, consequently enabling them to steal files, data, and credentials stored in the affected system, view the computer’s screen in real time, and log key strokes.
