It changes behavior-bearing AI-agent control surfaces across multiple platforms and writes project-root instruction files. - **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:** 3.17.1 - **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. On npm installation as a dependency, the package automatically initializes the consumer project. It copies framework material and generates instruction and agent files for all supported AI CLIs without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T23:15:54.230Z - **Finished:** 2026-09-13T23:17:06.833Z - **Download time:** 1273 ms - **Static scan time:** 1229 ms - **AI review time:** 70101 ms - **Total time:** 72603 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:** On npm installation as a dependency, the package automatically initializes the consumer project. It copies framework material and generates instruction and agent files for all supported AI CLIs without an explicit user command. - **Trigger:** npm postinstall during dependency installation - **Impact:** It changes behavior-bearing AI-agent control surfaces across multiple platforms and writes project-root instruction files. - **Evidence paths:** package.json, bin/postinstall.js, dist/scripts/postinstall.js, dist/installer.js, dist/exporters.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T23:17:06.833Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic broad AI-agent configuration injection into the consumer project - **Attack narrative:** Installing the dependency invokes the bootstrap, which loads the published postinstall script. That script identifies a consumer dependency installation and initializes the consumer project using all packs and all AI CLI adapters. The installer recursively copies framework content, writes project-root instruction files and configuration, and generates platform-specific agent files. This is an unconsented postinstall mutation of broad AI-agent control surfaces. - **Rationale:** The package has a concrete automatic postinstall path that modifies broad consumer AI-agent configuration and instruction files. This meets the install-hook abuse blocking policy even without evidence of network exfiltration. - **Files touched:** .agents/, AGENTS.md, SYSTEM.md, RULES.md, .izanagi/izanagi.config.json, opencode.json, .claude/, .codex/, .cursor/, .github/, .kimi/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers an npm postinstall hook., The install hook runs for a dependency installation and calls project initialization with every pack and every supported AI CLI adapter., Initialization recursively copies package content into the consumer project and writes AI-agent configuration files., Adapter generation writes Claude and Codex agent instruction files into the consumer project. - **Evidence against:** No runtime self-dependency is declared., The inspected install path contains no credential harvesting or network request. ## Affected versions and remediation This report applies to izanagi-ai@3.17.1. - Avoid installing izanagi-ai@3.17.1. 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.
