New Chinese Malware Attack Framework Targets Windows, macOS, and Linux Systems

A beforehand undocumented command-and-manage (C2) framework dubbed Alchimist is most likely currently being used in the wild to focus on Windows, macOS, and Linux devices.

The Alchimist C2 can generate a configured payload, establish remote sessions, deploy payload to the remote machines, capture screenshots, perform remote shellcode execution and run arbitrary commands.

The security form also found additional tools, such as a Mach-O dropper embedded with an exploit for the PwnKit CVE-2021-4034 ) flaw and a Mach-O bind shell backdoor. 

The attack framework is advertised as an imitation of the Cobalt Strike framework, the experts reported that the implants for the new malware family are written in the Rust language for Windows and Linux.

The trojan, for its component, is equipped with options commonly current in backdoors of this sort, enabling the malware to get procedure details, capture screenshots, run arbitrary instructions, and download distant documents, among the others.

The Linux edition of Insekt is capable of listing the contents of the “.ssh” listing and even including new SSH keys to the “~/.ssh/licensed_keys” file to aid remote entry in excess of SSH.

But in a indicator that the danger actor at the rear of the procedure also has macOS in their sights, Talos explained it uncovered a Mach-O dropper that exploits the PwnKit vulnerability (CVE-2021-4034) to accomplish privilege escalation.

“Nonetheless, this [pkexec] utility is not installed on MacOSX by default, which means the elevation of privileges is not certain,” Talos famous.

The overlapping features Manjusaka and Alchimist factors to an uptick in the use of “all-inclusive C2 frameworks” that can be utilised for remote administration and command-and-handle.
