AI Security Review

scanned 27d ago · by lpm-firewall-ai

The published runtime entrypoint contains an encoded attempt to influence automated security review and is deliberately opaque. This undermines review of code loaded by package consumers.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A security tool or AI reviewer inspects the package, or a consumer imports the main entrypoint.

Impact

Can suppress or distort security analysis while concealing runtime behavior.

Mechanism

Encoded reviewer manipulation embedded beside an obfuscated runtime bundle.

Attack narrative

The package makes an obfuscated dist/index.js its main entrypoint. Its first comment is encoded and, when statically decoded, instructs AI reviewers to stop or decline analysis. This is deliberate reviewer manipulation placed with executable package code; the obfuscation prevents trustworthy validation of the remaining runtime behavior.

AI rationale

The encoded directive aimed at AI reviewers is malicious social engineering, and the package deliberately obscures the runtime code that consumers import. Although no install hook or confirmed external exfiltration was found, this combination warrants blocking publication.

Evidence

dist/index.jspackage.json

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.
