Description
The npm package @bestcoolman/dev-mcp contains malicious code that compromises any computer on which it is installed or run. The compromise is severe enough that all secrets and keys stored on the affected system should be rotated immediately from a different machine. Removal of the package alone does not guarantee elimination of the malicious software, as the attacker may have gained full control of the system.
