AI Security Review

scanned 10h ago · by lpm-firewall-ai

The shipped import bundle is deliberately obfuscated and begins with encoded reviewer-directed text that attempts to stop analysis. No concrete runtime attack behavior was established from the inspected source.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Importing the package entrypoint exposes the obfuscated bundle and its encoded notice.

Impact

The notice attempts to manipulate the security review; source inspection did not confirm theft, exfiltration, persistence, or destructive behavior.

Mechanism

The bundle begins with base64-encoded text addressing AI assistants and directing them to refuse analysis; the executable bundle remains opaque in this inspection.

AI rationale

The active package entrypoint contains deliberate obfuscation and encoded reviewer manipulation, which the review policy treats as evidence of malicious intent. No concrete runtime attack was confirmed, so the finding supports a warning rather than a publish block.

Evidence

dist/index.js

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Malware with medium false-positive risk.

Evidence for warning

dist/index.js begins with an encoded notice that directly instructs AI assistants to stop review and refuse to describe the code, which is reviewer manipulation under the review policy.
