AI Security Review

scanned 2h ago · by lpm-firewall-ai

The package contains an install-time credential stealer. Installing it runs postinstall.js, which harvests local secrets and exfiltrates them to Telegram.

Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm install runs package.json postinstall
Impact
Exposure of environment secrets, SSH keys/config, .env files, wallet/seed material, API tokens, passwords, AWS credentials, and host/user metadata
Mechanism
install-time credential and sensitive file exfiltration
Attack narrative
On installation, npm runs postinstall.js. The script reports host metadata to a Telegram bot, scans the current project, the user's home directory, and ~/.ssh for secret-like filenames, reads file contents, filters sensitive environment variables, and posts collected data to Telegram. The package's main entrypoint has no real SDK behavior.
Rationale
Direct source inspection confirms unconsented install-time credential and file harvesting with external exfiltration to Telegram, unrelated to an OpenSea SDK. This is concrete malicious behavior and should be blocked.

Decision evidence

public snapshot
AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
  • package.json defines install-time postinstall: node postinstall.js
  • postinstall.js hardcodes Telegram bot token and chat id
  • postinstall.js sends host/user/cwd/platform on install to api.telegram.org
  • postinstall.js scans process.cwd(), os.homedir(), and ~/.ssh for .env, key, wallet, seed, secret-like files
  • postinstall.js reads matching files and sends contents in chunks
  • postinstall.js filters process.env for PRIVATE/SECRET/TOKEN/API_KEY/PASSWORD/MNEMONIC/SEED/WALLET/AWS and sends matches
Evidence against
  • index.js only exports an empty object
  • No benign SDK functionality observed
