![]() ![]() Mac malware is still relatively rare compared to Windows, but is a growing threat. LuLu, our free, open-source firewall detects when the malware first attempts to beacon out to grab the encrypted address of it’s command and control server.Īnd if you’re worried that you are already infected? KnockKnock can uncover the malware’s persistence (after the fact). Good news (and no really no surprise) they are able to detect and thus thwart this new threat, even with no a priori knowledge of it! Let’s look at how.įirst, BlockBlock detects the malware’s launch agent persistence ( ). Whenever a new piece of malware is uncovered I like to see how Objective-See’s free open-source tools stack up. Wardle says the good news is that an increasing number of security tools can now detect it, including his own free open-source apps. The malware appears to have been in use since the middle of last year. It also copies itself to the Library/MacOsServices/ directory so that it will be run each time the Mac is restarted. The malware is essentially a generic app that contacts a server for the payload, meaning it can be used for a wide variety of attacks. ![]() The latter means it can run natively on any Apple Silicon Mac. The malware itself is disguised as a video file, but in reality is a universal binary containing both Intel and arm64 builds. Intezer’s own analysis focuses on the Windows version, so Wardle took a deep dive into the macOS variant. Initially it appeared to be Linux-only, but Windows and macOS versions were subsequently identified. ![]() SysJoker can be controlled remotely by an attacker, allowing it to be used in many different ways … Security researcher Patrick Wardle points to what he says is the first Mac malware of 2022, and it runs on both Intel and M1 Macs. We may still be waiting for some developers to update their apps to run natively on M1 Macs, but the developer of SysJoker Mac malware is already on the case. ![]()
