AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete unconsented install-time credential theft and remote code execution, not a package-aligned build step. The visible theme code does not justify the concealed preinstall chain.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm install (preinstall)
Impact
Credential theft and attacker-controlled code execution in the installing user's environment.
Mechanism
downloaded Bun executes obfuscated credential-stealing payload
Attack narrative
The preinstall hook invokes setup.mjs, which uses a local or downloaded Bun binary to execute math_init.js. That large obfuscated payload dynamically loads system APIs, discovers token-bearing sources, sends collected data through network requests, and evals fetched response content. This is unrelated to the published theme runtime.
AI rationale
This is concrete unconsented install-time credential theft and remote code execution, not a package-aligned build step. The visible theme code does not justify the concealed preinstall 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 setup.mjs as preinstall.
- setup.mjs downloads Bun and executes math_init.js during install.
- math_init.js is a 728KB obfuscated payload with dynamic require, Function, and eval.
- math_init.js enumerates credential/token sources including GitHub tokens and sends data with fetch.
- Payload creates then removes a temporary marker, indicating guarded install-time execution.
- Theme dist code is unrelated to the preinstall payload.
Evidence against
- dist/*.js implements the advertised ThoughtSpot theme helpers.
- setup.mjs downloads from the visible GitHub Bun release URL, but uses it to run the hidden payload.
