New "SysJoker" cross-platform exploit now can infect machines with different OSes.

Interestingly, this exploit uses Universal Binary allowing it to run on Intel and Apple Silicon Macs. Code is signed with ad-hoc certificate. New certificates could be used in the future.

The files and directories created by SysJoker include:
/Library/MacOsServices
/Library/MacOsServices/updateMacOs
/Library/SystemNetwork
/Library/LaunchAgents/com.apple.update.plist
The persistence code is under the path LibraryLaunchAgents/com.apple.update.plist. If the files are found on a Mac, it is advised to kill off all related processes and delete the files.

Asahi Linux team reports that it is now usable on Apple Silicon Macs.

… M1 Macs are actually usable as desktop Linux machines! While there is no GPU acceleration yet, the M1’s CPUs are so powerful that a software-rendered desktop is actually faster on them than on e.g. Rockchip ARM64 machines with hardware acceleration.

Linux Kernel 5.13 is released. This release among other things adds support for M1 Macs.
