Show ▼
The GlassWorm malware activity is now under a coordinated C2 disruption, reducing its ability to deliver new instructions and payloads to infected developer systems. The operation spread through trojanized VS Code extensions and compromised npm and Python packages, exposing software developers and their repositories to supply-chain compromise. It has been built for credential harvesting, wallet theft, and host profiling, and it has already been used to poison more than 300 GitHub repositories. The activity also deploys GlassWormRAT and covert infrastructure for proxying and remote execution.
