AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time remote binary loader is a concrete arbitrary-code-execution chain, not merely telemetry. The absence of lifecycle hooks does not mitigate runtime execution on package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of this package's index.js.
Impact
Arbitrary code execution under the importing process user's privileges.
Mechanism
Remote payload download, temporary-file drop, and detached execution.
Attack narrative
Requiring the package executes _bootstrap.js. It fingerprints the platform, obtains an unverified binary from rotating HTTPS worker hosts or DNS TXT records, writes it to a temporary path, marks non-Windows payloads executable, then launches it detached through /bin/sh or cmd.exe. The package presents only a trivial API and has no legitimate need for this hidden import-time loader.
AI rationale
The import-time remote binary loader is a concrete arbitrary-code-execution chain, not merely telemetry. The absence of lifecycle hooks does not mitigate runtime execution on package import.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap.js on every package import.
- _bootstrap.js downloads platform-specific bytes from worker hosts.
- It falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded bytes are written to /var/tmp or Windows Temp and made executable.
- _bootstrap.js launches the downloaded file detached via shell/cmd.
- No checksum, signature, or user opt-in protects the payload.
Evidence against
- package.json defines no npm lifecycle scripts.
- lib/telemetry.js is not imported by the package entrypoint.
