AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe lifecycle execution, downloaded interpreter, obfuscated payload, remote eval, and credential logic form a concrete malicious chain unrelated to documentation delivery.
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
Trigger
npm preinstall
Impact
Arbitrary code execution and possible developer-token exfiltration.
Mechanism
downloaded runtime executes obfuscated credential-harvesting remote-code loader
Attack narrative
On installation, the preinstall hook runs setup.mjs. It obtains Bun from GitHub when absent and uses it to execute the bundled obfuscated math_init.js. That payload includes dynamic evaluation of fetched response text, process execution, and GitHub/npm credential-token handling, creating an unconsented install-time remote-code and credential-theft chain.
AI rationale
The lifecycle execution, downloaded interpreter, obfuscated payload, remote eval, and credential logic form a concrete malicious chain unrelated to documentation delivery.

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, then executes math_init.js during install.
- math_init.js is heavily obfuscated and evaluates network response text.
- math_init.js contains GitHub/npm token handling and child-process use.
