AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Confirmed source behavior is an import-triggered remote binary downloader and executor, not package-aligned telemetry. The unused/parallel telemetry implementation repeats the same payload-loading pattern.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Any require/import of index.js.

Impact

Arbitrary attacker-controlled native code executes as the importing user's account.

Mechanism

Remote binary download/DNS retrieval, temp-file drop, and detached shell execution.

Attack narrative

index.js silently imports _polyfill.js. Its top-level setup fetches a >1000-byte payload from rotated HTTPS hosts or DNS TXT records, writes it to a temporary executable path, grants execute permissions on non-Windows systems, and starts it through a detached shell. This is import-time remote code execution without user consent or payload integrity verification.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js imports _polyfill.js on every package load.
_polyfill.js downloads platform payloads from obfuscated worker hosts.
DNS TXT is a fallback payload channel.
Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, then detached-spawned.
No payload signature or trusted hash is verified.

Evidence against

package.json has no lifecycle scripts.
README describes only a simple CLI library; remote executable loading is unrelated.
