AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete import-time staged-payload execution chain, not telemetry: it retrieves and runs an unverified native binary without user action. The absence of lifecycle hooks does not mitigate execution caused by normal module 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

Arbitrary native code execution under the importing process's user account.

Mechanism

download, drop, chmod, and detached execution of an unverified remote payload

Attack narrative

The public entrypoint silently loads _compat.js. On import, it fetches a platform-specific executable from obfuscated remote hosts, falling back to DNS TXT chunks, writes it into a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The code suppresses errors and does not verify payload authenticity.

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 _compat.js during every package import.
_compat.js downloads platform-specific payloads over HTTPS or DNS TXT.
_compat.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached.
Payload hosts are obfuscated by string concatenation and failures are silently suppressed.
No payload integrity/signature verification is performed.

Evidence against

package.json contains no npm lifecycle scripts.
lib/telemetry.js is not imported by the public entrypoint; the malicious path is _compat.js.
