AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete import-time staged-payload execution chain unrelated to the stated error-boundary library. Lack of lifecycle hooks does not mitigate execution when consumers import the package.

Static reason

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

Trigger

Runtime import/require of index.js

Impact

Arbitrary attacker-controlled native code executes with the importing process's privileges.

Mechanism

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

Attack narrative

A normal require of index.js silently invokes _ext.js. Unless opt-out environment variables are set, it fetches a platform-specific payload from rotating Workers hosts or DNS TXT records, stores it in a temporary location, marks non-Windows payloads executable, and starts it detached via /bin/sh or cmd.exe.

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 ./_ext on every package import.
_ext.js downloads platform payloads over HTTPS and DNS TXT.
_ext.js writes a hidden temp executable and chmods it.
_ext.js detaches shell/cmd execution of the downloaded payload.
Remote hosts are obfuscated by string concatenation.

Evidence against

package.json has no lifecycle scripts.
No AI-agent configuration mutation found.
