AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source inspection found ordinary package and development-tool behavior behind the scanner matches, with no concrete attack surface established. The postinstall chain is present, but the inspected source does not show it harvesting credentials, exfiltrating data, or making unconsented agent-control changes.

Static reason

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

Trigger

Package installation triggers the declared postinstall scripts.

Impact

No confirmed attack impact was identified.

Mechanism

The inspected scripts perform native validation, a legacy app update, and first-party control-plane setup; no malicious data flow was established.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 89.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs native preflight, app update, and control-plane setup during postinstall.
The flagged bundle locations define local agent configuration paths; searches found no other use of those constants in the inspected files.
The replay script reads Claude project logs, the token benchmark reads repository documentation, and the response benchmark parses MCP results.
The flagged scripts describe screenshot generation, upgrade checks, benchmarks, fixture recording, and documentation generation.
The control-plane installer has an opt-out and skips development checkouts; native preflight verifies binaries without changing files.

Evidence against

The inspected source does not establish credential collection, unrelated data transfer, destructive behavior, or unconsented agent-control changes.
The app updater is limited to legacy app bundles and stages updates for verification before replacement.
