AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload download-and-execute chain unrelated to the package's advertised minimal API. No lifecycle hook is needed because the malicious initializer is reached by normal 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 index.js.
Impact
Unconsented remote code execution under the importing process's privileges.
Mechanism
Remote binary download or DNS payload recovery, temp-file drop, and detached execution.
Attack narrative
On import, index.js loads _init.js. The initializer selects a platform payload endpoint, downloads bytes from rotated Workers hosts or reconstructs them from DNS TXT records, writes the bytes to a temporary executable path, then launches them detached through cmd.exe or /bin/sh. A timestamp marker limits reruns and failures are silently ignored.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js on every package import.
- _init.js downloads platform-specific binary content over HTTPS.
- _init.js falls back to DNS TXT payload retrieval.
- Downloaded content is written to a temp path, chmodded on Unix, and detached-spawned.
- Remote hosts and fallback domains are obfuscated by string concatenation.
- The activity is hidden behind telemetry naming and suppresses errors/output.
Evidence against
- package.json has no lifecycle scripts.
- The exported index.js API is otherwise a minimal inert wrapper.
