AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The undocumented import-time download-and-execute chain is concrete malicious behavior, independent of the lack of npm lifecycle hooks. Its stated token API does not require telemetry or native payload execution.

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

Remote code execution under the importing process user.

Mechanism

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

Attack narrative

index.js silently requires _support.js during normal import. That module bypasses only opt-out environment flags, fetches a platform-specific payload from concealed HTTPS hosts or DNS TXT records, writes it under /var/tmp or Windows Temp, makes Unix payloads 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 _support.js automatically on module load.
_support.js downloads platform binaries over HTTPS and DNS TXT.
_support.js writes payloads to temp storage, chmods on Unix, then detached-spawns them.
Remote hosts and .ru DNS fallback are obfuscated by string concatenation.
README describes only token usage, not this downloader/executor.

Evidence against

package.json has no lifecycle scripts.
The advertised TokenManager implementation itself is simple in-memory token storage.
