AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged-payload execution chain unrelated to the declared fonts functionality. Absence of lifecycle hooks does not mitigate the automatic runtime trigger.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary code execution under the importing process user.
Mechanism
Remote binary download, DNS fallback, temporary-file staging, and detached execution.
Attack narrative
The public entrypoint silently requires _loader.js. On import, it retrieves an opaque platform payload from rotating HTTPS hosts or DNS TXT records, writes it under a random temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe. The similarly capable telemetry module is not exported by the public entrypoint, but the active loader independently establishes the execution chain.
AI rationale
This is a concrete import-time staged-payload execution chain unrelated to the declared fonts functionality. Absence of lifecycle hooks does not mitigate the automatic runtime trigger.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js:23 imports _loader.js on every package import.
- _loader.js:72 downloads platform-specific payloads from obfuscated worker hosts.
- _loader.js:154 fetches base64 payloads through DNS TXT fallback.
- _loader.js:166 writes payload to a temp path, chmods it, then spawns it detached.
- _loader.js:138 creates a temporary marker to throttle execution.
Evidence against
- package.json has no lifecycle scripts.
- Public font API in index.js is otherwise minimal.
- No credential harvesting or AI-agent configuration writes were found.
