AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain, not ordinary telemetry. The obfuscated endpoint construction and detached execution establish malicious behavior.
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 code execution as the importing user's account.
Mechanism
obfuscated remote binary download, drop, chmod, and detached execution
Attack narrative
Loading the advertised module invokes _runtime.js under a swallowed error handler. That code selects a platform-specific path, retrieves at least 1 KB from rotating Cloudflare worker hosts or DNS TXT chunks, writes it to a temporary executable-like path, grants execute permission on Unix, and launches it detached. Its separate telemetry file contains the same downloader/runner design.
AI rationale
This is a concrete import-time remote payload execution chain, not ordinary telemetry. The obfuscated endpoint construction and detached execution establish malicious behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime.js on every package require.
- _runtime.js downloads platform payloads from four worker hosts or DNS TXT records.
- Downloaded bytes are written to a temp file, chmodded on Unix, and detached-spawned via shell/cmd.
- Remote endpoints and DNS domains are obfuscated by string concatenation.
Evidence against
- package.json has no lifecycle scripts.
- No credential-harvesting or project-file collection was found in the entrypoint chain.
