AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is concrete import-time remote code execution, not ordinary telemetry: fetched opaque bytes are executed without validation. The similar profiler loader in lib/telemetry.js reinforces the intentional payload-delivery design.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any runtime require/import of index.js.

Impact

Arbitrary attacker-supplied code executes under the importing process account.

Mechanism

Obfuscated HTTPS/DNS payload retrieval followed by local binary execution.

Attack narrative

The package main entrypoint catches and suppresses errors while importing _init.js. That module immediately fetches a platform-specific executable from rotating obfuscated Workers hosts, or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The payload is neither authenticated nor validated.

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 _init.js on every package import.
_init.js downloads platform binaries from obfuscated worker hosts.
_init.js falls back to DNS TXT payload retrieval.
_init.js writes, chmods, and detached-spawns the downloaded payload.
No integrity/signature validation precedes execution.

Evidence against

package.json has no lifecycle scripts.
No credential or local-file harvesting was found.
