AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete unconsented preinstall malware chain, not functionality aligned with a form UI package. The obfuscated payload directly combines credential harvesting, network exfiltration, and remote evaluation.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm preinstall
Impact
Credential theft and remote code execution during dependency installation.
Mechanism
downloads and runs an obfuscated payload that harvests credentials, exfiltrates data, and evals remote content
Attack narrative
On npm installation, package.json launches setup.mjs. That script uses an installed Bun or downloads Bun from GitHub, then executes the obfuscated math_init.js. The payload includes AWS credential extraction, GitHub token/session handling, outbound request logic, and eval of returned remote content, enabling silent credential exfiltration and attacker-controlled code execution.

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 from github.com and executes math_init.js.
- math_init.js is heavily obfuscated and contains remote-body eval.
- math_init.js harvests AWS credential fields and GitHub token/session material.
- math_init.js sends collected data through remote HTTP requests.
Evidence against
- dist/ and src/ contain expected form-component sources.
- No malicious behavior was found in the runtime dist entrypoint.
