AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection shows checksum-verified helper downloads and user-configured provider calls for product features. The flagged gateway redirection and malicious agent-control behavior were not supported by the inspected source.

Static reason

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

Trigger

npm postinstall runs the helper installers; creating a prompted cron job queues summarization when a supported key is configured.

Impact

No malicious impact was established; the observed effects are helper installation and optional task labeling.

Mechanism

The installers verify downloaded binaries against pinned hashes. The summary feature sends a cron prompt to the configured DeepSeek-compatible endpoint to produce a short label.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

`package.json` runs two helper installers during postinstall; each downloads a release binary and rejects it if its SHA-256 differs from the pinned value.
The flagged provider code reads DeepSeek, Moonshot, and GLM keys from the user vault and supplies them to the Maestro SDK as API key overrides; no unrelated recipient is established there.
Creating a cron job with a prompt queues a summary; the summary request runs only when a configured key exists and sends the prompt to the DeepSeek-compatible endpoint to generate a task label.
Agent-related excerpts resolve conventional local Codex auth paths and write Claude rollout data under the local project history directory.
The `query-runtime.js` child process call runs a candidate browser helper with `--version` and checks its output.

Evidence against

The inspected source does not support the scanner’s claim that provider credentials are redirected to a fixed unofficial gateway.
The observed network requests serve binary installation and optional cron task labeling; no malicious transfer or agent-control mutation was identified.
