AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has an unconsented preinstall chain that bootstraps a runtime solely to execute a large obfuscated, credential/network-capable payload. This is concrete malicious install-time behavior, not package-aligned UI code.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Potential credential theft and arbitrary install-time code execution.
Mechanism
downloads a runtime and executes an obfuscated credential/network-capable payload
Attack narrative
`preinstall` executes `setup.mjs`, which either invokes an existing Bun binary or downloads Bun 1.3.13 from GitHub, extracts it to a temporary directory, and runs `math_init.js`. The 727KB obfuscated payload dynamically resolves Node APIs, uses child-process and filesystem capabilities, constructs authenticated network requests, and includes GitHub-token handling. This is unrelated to a navigation-menu component and creates a concrete install-time execution and credential-exfiltration chain.
AI rationale
The package has an unconsented preinstall chain that bootstraps a runtime solely to execute a large obfuscated, credential/network-capable payload. This is concrete malicious install-time behavior, not package-aligned UI code.

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` during preinstall.
- setup.mjs downloads Bun from GitHub and executes `math_init.js` at install time.
- math_init.js is a 727KB heavily obfuscated executable payload.
- math_init.js uses child_process, fs/os/path, dynamic Function/eval, HTTP logic, and token-handling code.
- The payload contains request construction with authorization data and GitHub-token paths.
Evidence against
- The declared package entrypoints are a Qlik/React navigation-menu bundle.
- The visible runtime bundle’s fetch usage is Qlik API functionality, separate from the install payload.
