Cybersecurity researchers have discovered a set of trojanized npm packages that masquerade as working calendar and streak utilities but are engineered to stealthily deliver an artificial intelligence (AI)-powered Linux implant dubbed RedC2 4.0.
14 distinct techniques documented for this family, organized by ATT&CK tactic.
The Linux variant of the beacon, once deployed, provides an interactive shell through "/bin/sh" ... after which it enters a command-processing loop to process incoming instructions from the operator, execute them via "/bin/sh," and send the results back.
When the module loads, it locates the bundled binary, marks it executable, and launches it as a detached background process. No install hook function call is needed; a single import anywhere in the dependency graph, even a transitive one, is enough to execute the payload.
The version was advertised by a threat actor named "MarlboroMan" on Hack Forums in early June 2026, describing it as a command-and-control (C2 or C&C) framework "built for evasion."
The C2 framework is also feature-rich, supporting terminal access, file transfer, staged payload delivery, data collection, multi-beacon operation, network visualization, host-to-host tunneling, and in-memory execution of Beacon Object Files (BOFs), .NET assemblies, and shellcode.
RedC2 EXT as well as a large language model (LLM)-driven component called Red Agent, the latter of which lets operators orchestrate complex post-exploitation tasks, such as network reconnaissance and credential dumping, using natural language commands.

The Linux variant of the beacon, once deployed, provides an interactive shell ... persistence, in-memory ELF execution, SOCKS5 proxying, and network pivoting.
