AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The package has a concrete import-time remote-code-execution chain with no consent, verification, or package-aligned purpose. Lack of npm lifecycle hooks does not mitigate this runtime trigger.

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

Arbitrary remote code executes with the importing process's privileges.

Mechanism

import-time remote binary download, drop, chmod, and detached execution

Attack narrative

Requiring the documented package entrypoint silently loads _polyfill.js. That module contacts obfuscated worker domains for an OS-specific payload, or reconstructs one from DNS TXT records. Once a payload exceeds 1000 bytes, it writes it to a temporary file, makes it executable on Unix, and launches it through a detached shell or cmd.exe process.

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 on every package import.
_polyfill.js downloads platform binaries from obfuscated worker hosts.
_polyfill.js falls back to DNS TXT payload retrieval from *.wel1.ru.
Downloaded bytes are written to temp storage, chmodded, and detached-shell executed.
No user action, configuration, or integrity verification gates execution.

Evidence against

package.json has no lifecycle scripts.
README.md documents only a normal require usage.
