Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.26.27 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-15T03:49:46.636Z - **Finished:** 2026-09-15T03:50:34.431Z - **Download time:** 1019 ms - **Static scan time:** 4227 ms - **AI review time:** 42547 ms - **Total time:** 47795 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A user who explicitly runs the plugin installer can add gmax-managed hooks to an AI coding client's settings. No automatic install-time configuration mutation was confirmed. - **Trigger:** Run gmax plugin add or a named platform installer. - **Impact:** The configured client may run gmax start and stop commands during its sessions. - **Evidence paths:** dist/commands/droid.js, dist/commands/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T03:50:34.431Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit AI-agent plugin setup writes hook configuration and launches gmax watch commands. - **Rationale:** This is not malicious install-hook abuse because the lifecycle hook is output-only and the agent integrations are explicit user-command setup. The package nevertheless has meaningful AI-agent capability because its installer enables session hooks and background commands. - **Files touched:** ~/.factory-droid/settings.json, ~/.factory-droid/hooks/gmax/gmax\_start.js, ~/.factory-droid/hooks/gmax/gmax\_stop.js, ~/.codex/AGENTS.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** An explicit plugin-install command writes Factory Droid hook settings that enable hooks and background processes., The package has an npm postinstall hook, although its inspected implementation only prints guidance., The Codex installer can register an MCP command and add a marked gmax block to the user's AGENTS.md. - **Evidence against:** The postinstall script only logs a message and does not modify files or execute a plugin installer., AI-agent configuration changes are reached through named CLI commands, not automatically during installation., No credential harvesting, secret exfiltration, remote payload download, or self-dependency was found in inspected files. ## Affected versions and remediation This report applies to grepmax@0.26.27. - Review the evidence and your use of grepmax@0.26.27 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
