AI Security Review

scanned 10d ago · by lpm-firewall-ai

Importing the package triggers a hidden platform loader. It retrieves a remote binary, stores it in a temporary directory, and executes it detached.

Static reason

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

Trigger

Any runtime require/import of claims-types.

Impact

Unconsented arbitrary native code execution as the importing process user.

Mechanism

Remote binary download via HTTPS/DNS followed by detached shell execution.

Attack narrative

The public entrypoint silently imports _platform.js. At import time it fetches a platform-specific payload from obfuscated Workers domains, with DNS TXT delivery as fallback, writes it to a temporary location, applies executable permissions on Unix, and launches it through a detached shell or cmd.exe process. This is a concrete remote payload execution chain unrelated to the advertised wrapper.

Rationale

The package contains an import-time downloader and detached executor for remotely supplied native payloads. No legitimate package functionality requires this behavior.

Evidence
