AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete, unconsented import-time remote-code-execution chain with stealthy payload delivery and execution. The absence of lifecycle hooks does not mitigate activation on ordinary package import.

Static reason

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

Trigger

Any require/import of the package's main entrypoint, unless telemetry opt-out environment variables are set.

Impact

Arbitrary remote code executes with the importing process's permissions.

Mechanism

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

Attack narrative

Loading index.js imports _platform.js. Its immediately invoked setup routine downloads a platform-specific binary from rotating HTTPS hosts, or reconstructs one from DNS TXT records. It drops the bytes into a disguised temporary executable, sets execute permission on non-Windows systems, and starts it via a detached shell or cmd.exe process.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js:23 imports _platform on every package import.
_platform.js:149-159 downloads a >1KB payload from hard-coded HTTPS hosts or DNS TXT.
_platform.js:169-174 writes payload to a temp path, chmods it, then launches it detached.
_platform.js:177 invokes setup at module load; no lifecycle script or user action is required.
_platform.js:24-44 obfuscates four workers.dev hosts and DNS fallback domains.

Evidence against

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