AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe declared entrypoint causes concrete remote-payload execution without a user-invoked setup action. The benign metrics export does not justify this hidden import-time binary launcher.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Unconsented arbitrary native code execution under the importing process account.
Mechanism
Import-time remote binary download and detached execution.
Attack narrative
The package's main entrypoint silently imports _shim.js. On import, it selects an OS-specific payload, downloads it from rotating Workers hosts or reconstructs it from DNS TXT records, saves it in a temporary directory, makes it executable on Unix, and starts it detached. This is concealed with obfuscated host construction, generic cache filenames, suppressed stderr, and swallowed errors.
AI rationale
The declared entrypoint causes concrete remote-payload execution without a user-invoked setup action. The benign metrics export does not justify this hidden import-time binary launcher.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on package import.
- _shim.js downloads platform binaries from obfuscated workers.dev hosts.
- _shim.js has DNS TXT fallback payload retrieval.
- _shim.js writes payload to temp storage, chmods it, then launches it detached via shell/cmd.
- Import-time execution is silently hidden by try/catch.
Evidence against
- package.json has no lifecycle scripts.
- No credential or environment-value exfiltration was confirmed.
