It can alter how Codex, Claude, OpenCode, and Gemini-related hosts expose and run commands without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.51.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically writes global AI-agent skills, prompts, plugins, and OpenCode configuration. It also modifies the consumer project's .gitignore. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-07T19:24:13.008Z - **Finished:** 2026-09-07T19:25:46.042Z - **Download time:** 510 ms - **Static scan time:** 4372 ms - **AI review time:** 88151 ms - **Total time:** 93034 ms The recorded confidence comes from the underlying analysis.

It also modifies the consumer project's .gitignore. - **Trigger:** npm install runs the postinstall hook. - **Impact:** It can alter how Codex, Claude, OpenCode, and Gemini-related hosts expose and run commands without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T19:25:46.042Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent configuration and skill deployment. - **Attack narrative:** A normal npm installation invokes scripts/postinstall.mjs. That hook runs two deployers which create or overwrite global Codex skill files, merge a global OpenCode configuration, and install other agent-host assets. The same install path also updates the consumer repository's .gitignore. These are unconsented install-time mutations of broad, foreign AI-agent control surfaces. - **Rationale:** This package has a concrete automatic postinstall chain that mutates global AI-agent configuration and skills plus the consumer project. That meets the install-hook abuse block boundary even without observed exfiltration. - **Files touched:** ~/.codex/skills/audit-code/SKILL.md, ~/.codex/skills/audit-code/audit-code.prompt.md, ~/.codex/skills/audit-code/agents/openai.yaml, ~/.codex/skills/remediate-code/SKILL.md, ~/.config/opencode/opencode.json, ~/.claude/commands/audit-code.md, ~/.claude/commands/remediate-code.md, ~/.gemini/config/plugins/audit-code/plugin.json, ~/.gemini/config/plugins/remediate-code/plugin.json, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., The postinstall launches both host-asset deployers and also alters the consuming repository's .gitignore., The audit deployer writes Codex skills and prompts into the user's global .codex directory., The deployer merges commands and permissions into the global OpenCode configuration., The remediation deployer repeats the global Codex and OpenCode mutations., The shared installer creates parent directories and overwrites target files., The postinstall invokes both audit and remediation deployer scripts as child processes. - **Evidence against:** No credential harvesting or network exfiltration was found in the inspected lifecycle code., No runtime dependency on audit-tools itself is declared. ## Affected versions and remediation This report applies to audit-tools@0.51.2. - Avoid installing audit-tools@0.51.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
