AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is concrete import-time remote code execution with obfuscated endpoints and no user-directed feature activation. The absence of npm lifecycle scripts does not mitigate runtime compromise on import.

Static reason

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

Trigger

require/import of index.js

Impact

Arbitrary attacker-controlled code runs as the importing user.

Mechanism

remote binary download, temporary drop, and detached execution

Attack narrative

The public entrypoint loads _polyfill.js. Its import-time init fetches a platform-specific binary from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It drops the bytes in a temporary path, makes non-Windows files executable, and launches them detached through a shell 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 _polyfill on every package load.
_polyfill.js downloads platform payloads from workers.dev hosts.
DNS TXT fallback reconstructs a base64 payload from wel1.ru.
Downloaded bytes are written to temp, chmodded, then detached-spawned.

Evidence against

package.json has no lifecycle scripts.
lib/telemetry.js is not imported by the public entrypoint.
