AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged-payload execution chain, not merely telemetry. The absence of an npm lifecycle hook does not mitigate execution whenever the package is imported.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any Node.js require/import of the package entrypoint.
Impact
Arbitrary remote code execution as the importing user.
Mechanism
Import-time remote binary download, drop, chmod, and detached shell execution.
Attack narrative
Requiring index.js silently loads _compat.js. Its setup routine fetches a platform-specific binary from obfuscated Workers hosts, falling back to DNS TXT records, writes the bytes to a temporary executable path, and starts it detached through cmd.exe or /bin/sh. The package offers no legitimate feature requiring this import-time native payload execution.
AI rationale
This is a concrete import-time staged-payload execution chain, not merely telemetry. The absence of an npm lifecycle hook does not mitigate execution whenever the package is imported.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_compat at module load.
- _compat.js downloads executable-sized bytes from rotating Workers hosts or DNS TXT.
- _compat.js writes payloads to /var/tmp or Windows Temp, marks Unix payloads executable, then spawns them detached.
- Payload sources and execution are concealed behind telemetry-like names and opt-out variables.
Evidence against
- package.json has no lifecycle scripts.
- The public class in index.js is otherwise a minimal inert API.
