AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe preinstall hook executes an obfuscated credential-harvesting payload unrelated to the Slate React library. Normal editor code in dist does not mitigate the install-time compromise.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Compromise of developer GitHub credentials and local environment data during installation.
Mechanism
remote runtime bootstrap and obfuscated credential exfiltration
Attack narrative
On installation, package.json invokes setup.mjs. It downloads and runs Bun if needed, then executes the bundled obfuscated math_init.js. Static inspection of that payload shows dynamic code execution, process spawning, credential/token collection including GitHub-token handling, and network-request logic, creating an unconsented install-time 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` during preinstall.
- setup.mjs downloads Bun from GitHub and executes `math_init.js`.
- math_init.js is a large, heavily obfuscated active payload.
- math_init.js contains dynamic Function/eval and child_process use.
- Decoded control flow in math_init.js scans GitHub-token sources and sends data through network requests.
Evidence against
- dist/index.js and dist/index.es.js contain normal Slate React editor code.
- No malicious behavior was found in the published runtime entrypoints.
