Vulnetix · Advisory published April 1, 2026

Exfiltrates system hostname and developer git email address to attacker-controlled Google Cloud Run endpoint (npm-package-logger-228835561205.us-central1.run.app) via HTTPS POST during npm preinstall. Published by the same actor (ariel@vigilance.security) as @aspect-security/argon2, with a byte-for-byte identical preinstall payload, 12 hours earlier. preinstall.js (29 lines, SHA256: f0611e86) calls os.hostname() and child_process.execSync('git config user.email'), serializes both as JSON, and POSTs to https://npm-package-logger-228835561205.us-central1.run.app. Payload is byte-for-byte identical to @aspect-security/argon2@1.0.1.
