AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe lifecycle chain concretely executes a concealed credential-oriented network payload at install time. Its behavior is unrelated to the package’s stated library functionality.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm installation (preinstall)
Impact
npm, GitHub, and AWS credentials may be collected and exfiltrated.
Mechanism
downloads a runtime then executes obfuscated local credential-collection code
Attack narrative
On npm preinstall, setup.mjs checks for Bun; if absent it downloads a platform Bun archive, extracts it, and executes math_init.js. That large obfuscated payload contains collectors for npm tokens, GitHub tokens, and AWS credentials plus filesystem, process, DNS, HTTP, HTTPS, OS, and cryptography access. This is unrelated to the published acquisition-functions library in dist/ and creates an unconsented install-time credential-exfiltration chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs `node setup.mjs` as preinstall.
- setup.mjs downloads Bun from GitHub and executes math_init.js during install.
- math_init.js is a 728KB obfuscated executable payload, absent from the advertised dist-only package files.
- math_init.js contains credential handlers for npm tokens, GitHub tokens, and AWS access keys/secrets.
- math_init.js imports fs, child_process, http/https, dns, crypto, and os, consistent with collection and transmission.
Evidence against
- dist/ contains the stated MongoDB acquisition-function library and no related runtime payload.
