AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe preinstall hook executes a concealed, credential-aware payload unrelated to the chat UI package. Its remote runtime bootstrap and dynamic evaluation are concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm install/preinstall
Impact
Potential theft of npm, AWS, and other local credentials with arbitrary code execution.
Mechanism
remote runtime bootstrap and obfuscated credential-harvesting payload execution
Attack narrative
Installing the package invokes setup.mjs. It executes math_init.js with Bun, downloading a Bun binary from github.com first if Bun is unavailable. The payload is heavily obfuscated but contains npm-token and AWS-key collection logic, child-process use, and eval of decoded content, establishing an install-time credential theft and arbitrary execution chain.
AI rationale
The preinstall hook executes a concealed, credential-aware payload unrelated to the chat UI package. Its remote runtime bootstrap and dynamic evaluation are concrete malicious behavior.

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 at preinstall.
- setup.mjs downloads Bun from github.com if absent, then executes math_init.js.
- math_init.js is a 727KB obfuscated executable payload.
- math_init.js contains credential-handling paths for npm tokens and AWS keys.
- math_init.js imports child_process and evaluates decoded code.
Evidence against
- dist/ and src/ implement the declared chat UI/SSE library.
- No malicious behavior was found in the normal dist entrypoint.
