AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe malicious behavior is directly wired into preinstall and concealed in an unrelated obfuscated payload; the benign runtime module does not justify it.
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 installation (preinstall)
Impact
Potential credential theft and arbitrary command execution during dependency installation.
Mechanism
preinstall executes obfuscated credential-capable payload
Attack narrative
The preinstall hook invokes setup.mjs, which runs math_init.js through an existing or downloaded Bun runtime. math_init.js is a large obfuscated payload rather than package functionality and includes GitHub-token-related handling alongside filesystem, network, and child-process primitives. This creates an unconsented install-time credential-exfiltration and command-execution path.
AI rationale
The malicious behavior is directly wired into preinstall and concealed in an unrelated obfuscated payload; the benign runtime module does not justify it.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs setup.mjs via preinstall.
- setup.mjs executes math_init.js with Bun, downloading Bun first if absent.
- math_init.js is a 728KB obfuscated executable payload.
- math_init.js contains GitHub-token handling (ghtoken, ghs_old, ghs_jwt), network requests, filesystem access, and child-process execution.
Evidence against
- index.js is a small conversation-context implementation with no network or process actions.
- The only clear setup.mjs URL is a Bun GitHub release download.
