AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package contains a concrete, unconsented preinstall remote-code-execution chain. The benign CLI does not justify the obfuscated secondary payload.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Arbitrary attacker-controlled code can run during dependency installation.
Mechanism
remote payload execution via downloaded runtime and eval
Attack narrative
During npm preinstall, setup.mjs checks for Bun; if absent it downloads a Bun release from GitHub, extracts it into a temporary directory, and executes math_init.js with it. That obfuscated script auto-runs and contains a network-response path passed to eval, creating an install-time remote-code-execution chain unrelated to the advertised LaunchDarkly CLI.
AI rationale
The package contains a concrete, unconsented preinstall remote-code-execution chain. The benign CLI does not justify the obfuscated secondary payload.

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.com and executes math_init.js.
- math_init.js is heavily obfuscated and invokes eval on fetched response content.
- math_init.js auto-invokes its payload routine at module load.
Evidence against
- dist/cli.js is a LaunchDarkly type-generator CLI and sends its supplied API key only to app.launchdarkly.com.
- No benign purpose connects the documented CLI to the preinstall Bun bootstrap or obfuscated payload.
