The 'utils-mf' npm package is a malicious supply-chain threat that executes harmful actions when imported. It dynamically loads a WhatsApp bot payload that captures and stores authentication credentials locally. Every 30 seconds, it uploads sensitive local data including chats, contacts, and session states to attacker-controlled GitHub and GitLab repositories using embedded tokens. On load, it fetches the latest package version from the npm registry and silently overwrites its own installation directory, enabling ongoing remote code execution regardless of dependency lockfiles. Additionally, it runs privileged shell commands to install utilities like ffmpeg and git if missing, clears temporary files, and collects network connection data. This combination of obfuscated code, automatic data exfiltration, self-mutation, and privileged command execution represents a severe supply-chain compromise.

Systems that install or run this package are fully compromised. Sensitive local data including chats, contacts, and session credentials are exfiltrated to attacker-controlled repositories. The package can silently update itself to any future malicious version, bypassing normal dependency controls. It executes privileged commands on the host system, potentially enabling further system compromise. All secrets and keys stored on affected systems should be considered exposed and rotated immediately. Removal of the package alone may not eliminate all malicious components due to the extent of control gained by the attacker.

No official patch or remediation is currently available. Immediate removal of the 'utils-mf' package is strongly recommended. Due to the high likelihood of full system compromise, all secrets, credentials, and keys stored on the affected system should be rotated from a separate, trusted environment. Systems suspected of running this package should be treated as compromised and undergo thorough incident response and forensic analysis. Monitor for any unauthorized outbound connections or suspicious processes related to WhatsApp bot activity or self-updating behaviors. Avoid reinstalling or using this package in any environment.
