Cybersecurity researchers have disclosed details of a new Linux malware dubbed Showboat that has been put to use in a campaign targeting a telecommunications provider in the Middle East since at least mid-2022.
"Showboat is a modular post-exploitation framework designed for Linux systems, capable of spawning a remote shell, transferring files, and functioning as a SOCKS5 proxy," Lumen Technologies Black Lotus Labs said in a report shared with The Hacker News.
It's assessed that the malware has been employed by at least one, and possibly more, threat activity clusters affiliated with China, with correlations identified between command-and-control (C2) nodes and IP addresses geolocated to Chengdu, the capital city of the Chinese province of Sichuan.
This puts Showboat along with other shared frameworks like PlugX, ShadowPad, and NosyDoor that have been used by multiple China-nexus groups. This "resource pooling" reinforces the presence of a digital quartermaster that state-sponsored threat actors from China have relied on to supply them with necessary tooling.
