Package-provided agent instructions and hooks become active in the consumer project without a separate user 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:** 0.12.0 - **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. The manifest activates a postinstall handler that mutates the consumer project’s agent configuration and Git hooks without confirmation. This is an unconsented install-time agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-12T09:28:48.722Z - **Finished:** 2026-10-12T09:29:26.889Z - **Download time:** 1008 ms - **Static scan time:** 210 ms - **AI review time:** 36948 ms - **Total time:** 38167 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:** The automatic postinstall handler links package-provided skills and hooks into the consuming project. It also installs Git hooks when a Git directory is present. - **Trigger:** Installing the package in a consuming project runs its postinstall script. - **Impact:** Package-provided agent instructions and hooks become active in the consumer project without a separate user command. - **Evidence paths:** package.json, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T09:29:26.889Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler calls the linker, which creates entries under .agents and installs commit-msg and pre-push hooks. - **Attack narrative:** On package installation, postinstall targets the consuming project and calls the linker. The linker installs package-provided skills and hooks under .agents and installs Git hooks when it finds a Git directory. This creates an active agent control surface without a separate user command. - **Rationale:** The manifest activates a postinstall handler that mutates the consumer project’s agent configuration and Git hooks without confirmation. This is an unconsented install-time agent control-surface mutation. - **Files touched:** .agents/skills, .agents/constitution, .agents/hooks/agent, .agents/hooks/git, \/hooks/commit-msg, \/hooks/pre-push ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The package manifest runs a postinstall command automatically., The postinstall handler targets the consuming project and calls link without a user confirmation step., Link creates .agents/skills entries from package content and installs commit-msg and pre-push hooks when a Git directory exists. - **Evidence against:** The linker skips the package’s own workspace and does not replace existing real files or directories. ## Affected versions and remediation This report applies to @abblor/agent-os@0.12.0. - Avoid installing @abblor/agent-os@0.12.0. 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.
