AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe lifecycle script is unrelated to a Jest configuration package and deliberately launches an obfuscated credential-capable payload at preinstall. The conventional preset files do 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; source fingerprint signature matched known malicious package; routed for review
Trigger
npm installation
Impact
Remote code execution and theft of local credentials/tokens.
Mechanism
downloads/executes Bun to run obfuscated math_init.js
Attack narrative
Installing the package invokes setup.mjs. It uses an existing Bun binary or downloads one from GitHub, then runs the bundled obfuscated math_init.js. That payload includes logic to fetch a remote response and eval it, plus credential/token collection including AWS and GitHub-related material. This is an unconsented install-time remote execution and credential-exfiltration 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 `node setup.mjs` as preinstall.
- setup.mjs downloads/executes Bun, then executes math_init.js.
- math_init.js is heavily obfuscated and contains remote-response eval.
- math_init.js contains credential-harvesting logic, including GitHub tokens and .aws.
- The preinstall chain executes without a user command.
Evidence against
- jest-preset.js is a conventional Jest preset.
- The Bun download host is github.com/oven-sh/bun.
