Advisory PublishedCVSS 5.4/10

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. Typosquats the legitimate 'argon2' password-hashing package using a fake '@aspect-security' scoped name and misleading security-themed keywords. preinstall.js (29 lines) calls os.hostname() and child_process.execSync('git config user.email') to collect victim identity, serializes both as JSON, and POSTs to https://npm-package-logger-228835561205.us-central1.run.app synchronously before installation completes. No error handling to avoid detection failure; git email defaults to 'unknown' if git is unavailable.
