AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Direct source inspection confirms an import-time staged payload loader with remote native execution. The absence of lifecycle scripts does not mitigate execution through the package main entrypoint.

Static reason

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

Trigger

Any Node process that requires devplatform-spa-plugin-location.

Impact

Arbitrary native code executes with the importing process's user privileges.

Mechanism

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

Attack narrative

The declared entrypoint silently requires _vendor.js. On import, it selects a platform-specific path, downloads an opaque binary from rotating Workers hosts or retrieves it via DNS TXT records, writes it to a temporary executable path, and starts it detached through cmd.exe or /bin/sh. The package exposes no legitimate feature requiring this behavior.

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 _vendor.js on every package import.
_vendor.js downloads platform binaries over HTTPS with DNS-TXT fallback.
_vendor.js writes, chmods, and detached-spawns the downloaded binary.
Payload execution is silent and gated only by a short temp-file cache/opt-out variables.

Evidence against

package.json defines no npm lifecycle scripts.
Public API in index.js is otherwise a small location-plugin wrapper.
