Threats Tagged 'self-replicating malware'

The npm ecosystem experienced a critical shift in September 2025 with the Shai-Hulud worm, marking the transition from isolated attacks to systematic supply chain compromises. In April 2026, TeamPCP launched a coordinated campaign through a malicious @bitwarden/cli package targeting multiple distribution channels including Docker Hub, GitHub Actions, and VS Code extensions. The multi-stage payload employs advanced obfuscation, harvests credentials from cloud providers and developer workstations, exfiltrates data through encrypted HTTPS and GitHub repositories, and self-propagates by backdooring npm packages using stolen tokens. The malware implements GitHub's search API as a resilient command-and-control fallback mechanism and features anti-detection measures including Russian locale killswitches. This represents an evolution toward wormable propagation, infrastructure-level persistence, and dormant payloads that activate under specific conditions.
