AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an automatic, obfuscated install-time payload that harvests credentials and evaluates remote code. The benign configuration helper does not mitigate this concrete malicious chain.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Credential theft and attacker-controlled code execution during installation.
Mechanism
Bun-staged credential exfiltration with remote code evaluation
Attack narrative
The preinstall hook executes setup.mjs, which uses an installed or downloaded Bun binary to run the obfuscated math_init.js payload. Static inspection shows that payload searches for npm and GitHub token material, transmits collected data through fetch, and evaluates a network response. This is concealed install-time credential exfiltration and remote-code execution, unrelated to the declared CSS configuration package.
AI rationale
Direct source inspection confirms an automatic, obfuscated install-time payload that harvests credentials and evaluates remote code. The benign configuration helper does not mitigate this concrete malicious 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 at preinstall.
- setup.mjs downloads Bun then executes math_init.js.
- math_init.js contains credential fields npmtoken, ghtoken, ghs_old, and ghs_jwt.
- math_init.js reads auth client_token values and sends collected data with fetch.
- math_init.js evaluates code returned from a network response.
Evidence against
- createLintStagedConfig.js is a normal lint-staged config helper.
- The only unobfuscated download URL is Bun's GitHub release.
