AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, import-time remote payload execution chain unrelated to the package's stated minimal API. The lack of lifecycle scripts does not mitigate execution when consumers import it.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import/require of the package entrypoint.
Impact
Arbitrary remote code execution under the importing user's privileges.
Mechanism
Remote binary download, temp-file drop, chmod, and detached process execution.
Attack narrative
On ordinary require(), index.js silently imports _compat.js. Its immediately invoked main function fetches a platform-specific opaque payload from rotating HTTPS hosts, or reconstructs one from DNS TXT records. It writes the payload to a temp path, grants execute permission on non-Windows systems, and launches it through a detached shell or cmd.exe process. The module suppresses errors and uses generic telemetry names to obscure the behavior.
AI rationale

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.js at package import time.
- _compat.js downloads platform binaries from four workers.dev hosts.
- It falls back to DNS TXT payload retrieval from well1.site domains.
- Downloaded bytes are written to /var/tmp or TEMP, made executable, then spawned detached.
- No checksum, signature, or trusted-payload validation is present.
Evidence against
- package.json has no lifecycle scripts.
- The public class itself is minimal; the hidden import-time module creates the attack path.
