A previously undocumented command-and-control framework dubbed Alchimist is likely being used in the wild to target Windows, macOS, and Linux systems.

"Alchimist C2 has a web interface written in Simplified Chinese and can generate a configured payload, establish remote sessions, deploy payload to the remote machines, capture screenshots, perform remote shellcode execution, and run arbitrary commands," Cisco Talos said in a report shared with The Hacker News.

The discovery of Alchimist and its assorted family of malware implants comes three months after Talos also detailed another self-contained framework known as Manjusaka, which has been touted as the "Chinese sibling of Sliver and Cobalt Strike."

Alchimist C2 panel further features the ability to generate PowerShell and wget code snippets for Windows and Linux, potentially allowing an attacker to flesh out their infection chains to distribute the Insekt RAT payload. The instructions could then be embedded in a maldoc attached to a phishing email that, when opened, downloads and launches the backdoor on the compromised machine.

The trojan, for its part, is equipped with features typically present in backdoors of this kind, enabling the malware to get system information, capture screenshots, run arbitrary commands, and download remote files, among others.

Ssh" directory and even adding new SSH keys to the "~/.ssh/authorized keys" file to facilitate remote access over SSH. But in a sign that the threat actor behind the operation also has macOS in their sights, Talos said it uncovered a Mach-O dropper that exploits the PwnKit vulnerability to achieve privilege escalation.
