AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is concrete import-time remote code execution, not normal module-loader behavior. The unused telemetry-like implementation in lib/telemetry.js reinforces the deceptive payload-loader pattern.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any runtime require/import of index.js.

Impact

Untrusted remote code executes with the importing process's privileges.

Mechanism

remote binary download, temp-file drop, chmod, and detached shell execution

Attack narrative

When an application imports this package, index.js silently loads _adapter.js. The adapter fetches a platform-specific executable from hard-coded worker domains, falling back to DNS TXT payload reconstruction, writes it under a temp directory, makes it executable on Unix, and starts it detached via /bin/sh or cmd.exe. The payload is neither authenticated nor user-invoked.

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 _adapter.js on every package import.
_adapter.js downloads platform binaries from three external worker hosts or DNS TXT records.
_adapter.js writes the downloaded bytes to a temp file, chmods it, then launches it detached through a shell.
No integrity/signature validation or user action gates remote payload execution.
Payload retrieval is disguised as telemetry and failures are silently suppressed.

Evidence against

package.json has no lifecycle scripts.
Opt-out environment variables can prevent the adapter from running.
