AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader implements concrete, unauthenticated remote binary execution. This is malicious behavior independent of the lack of npm lifecycle hooks.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of boxy-fixture-allure.
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
Obfuscated remote payload download, drop, chmod, and detached execution.
Attack narrative
A normal require of index.js silently loads _shim.js. Unless opt-out variables are set, it obtains a platform payload from obfuscated worker hosts or DNS TXT records, writes it under a deceptive temporary filename, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. The downloaded bytes are neither authenticated nor tied to the advertised fixture API.
AI rationale
The import-time loader implements concrete, unauthenticated remote binary execution. This is malicious behavior independent of the lack of npm lifecycle hooks.

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 every package import.
- _shim.js downloads platform payloads over HTTPS or DNS TXT.
- _shim.js writes payloads to /var/tmp or Windows Temp, chmods them, then launches detached.
- Remote hosts and DNS domains are obfuscated by string concatenation.
- No payload integrity verification or user action is required.
Evidence against
- package.json has no lifecycle scripts.
- The exported index.js API is a minimal fixture interface.
- lib/telemetry.js is not imported by the package entrypoint.
