Description

The @emcd-vue/auth npm package is a malicious supply-chain attack component impersonating a legitimate Russian cryptocurrency exchange's internal tooling. It contains no legitimate code but a heavily obfuscated postinstall script that downloads and executes a platform-specific payload, exfiltrates host metadata, and persists beyond npm installation. The package targets versions 6.4.5, 6.4.8, 6.4.9, and 7.0.0. Systems with this package installed should be considered fully compromised, and all secrets should be rotated from a clean environment.

Impact

Any system with this package installed is considered fully compromised. The attacker gains persistent remote code execution via a multi-stage payload, exfiltrates host metadata and environment variables (including credentials), and can maintain control beyond the npm installation process. This can lead to unauthorized access, data theft, and further malicious activity on the affected system.

Defensive guidance

Immediate removal of the @emcd-vue/auth package versions 6.4.5, 6.4.8, 6.4.9, and 7.0.0 is required. Because the package grants full system compromise, all secrets and credentials on the affected system should be considered compromised and rotated from a clean, trusted environment. Full system reimaging or forensic analysis is recommended to ensure complete removal of any persistent malicious components. Monitor for any signs of compromise related to this package and avoid installing packages from untrusted or suspicious npm scopes.
