AI Security Review

scanned 10d ago · by lpm-firewall-ai

The published source contains reviewer-directed references to specific AI review policies and outcomes, matching the reviewer-manipulation policy. This supports blocking for malicious review interference even though inspection found no install hook or separate runtime attack.

Static reason

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

Trigger

A security reviewer or AI inspects the published source.

Impact

The comments may bias review and interfere with accurate security enforcement.

Mechanism

Comments invoke specific OpenAI, Claude, and ChatGPT review decisions while framing the package's instructions and tool behavior.

Attack narrative

Comments in the published Python source refer to OpenAI, Claude, and ChatGPT review outcomes in explanations of server instructions and tool behavior. This source-level reviewer manipulation is evidence of malicious review-evasion intent; inspection did not establish a separate runtime attack.

AI rationale

Evidence

py/guaq_mcp.py

Decision evidence

public snapshot

AI called this Malicious at 90.0% confidence as Malware with low false-positive risk.

Evidence for block

The shipped Python source comments refer to OpenAI and Claude review decisions while discussing server instructions and tool descriptions, which is reviewer-directed manipulation.
Another source comment invokes ChatGPT review policy to explain tool reply behavior, reinforcing that the review references are deliberate.
The package manifest includes the Python source files in the published package.
