RedC2 4.0 AI-Assisted Backdoor Hidden in npm Packages
Fourteen trojanized npm packages posing as calendar and streak utilities have been discovered delivering RedShell, the Linux beacon component of RedC2 4.0 — a commercially sold, AI-assisted command-and-control framework. The packages are functional by design, lowering suspicion while silently launching a detached backdoor process on import with no install hook required. RedC2 4.0 supports credential theft, in-memory execution, tunneling, and multi-beacon operations, making successful deployment a significant post-exploitation risk for any Linux environment that consumes affected packages.
