Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Unconsented control-surface mutation can cause installed AI agents to load package-provided instructions. - **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:** 1.10.0 - **Selected version is latest:** Yes - **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. This is a concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, meeting the blocking policy. No separate exfiltration chain is required for this verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-08-14T14:19:30.437Z - **Finished:** 2026-08-14T14:20:13.757Z - **Download time:** 260 ms - **Static scan time:** 46 ms - **AI review time:** 43013 ms - **Total time:** 43320 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:** npm installation automatically modifies multiple foreign AI-agent skill directories. It creates directories, removes matching prior skills, and links this package's skills into them. - **Trigger:** npm postinstall - **Impact:** Unconsented control-surface mutation can cause installed AI agents to load package-provided instructions. - **Evidence paths:** package.json, bin/skills-link - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:20:13.757Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global symlink injection into agent skill directories - **Attack narrative:** During npm installation, the postinstall first checks all supported agent directories and, if any skill is absent or differs, reruns the linker globally. The linker creates agent skill directories, deletes existing matching skill directories or symlinks, and symlinks the package's skills into OpenCode, Claude, Codex, Cursor, and .agents locations without an explicit user command. - **Rationale:** This is a concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, meeting the blocking policy. No separate exfiltration chain is required for this verdict. - **Files touched:** package.json, bin/skills-link, skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Install-time postinstall invokes the linker globally when its check finds drift., The linker targets five separate agent-control skill directories, including Claude, Codex, Cursor, and OpenCode., On install it removes existing same-named skill directories/symlinks and replaces them with package symlinks. - **Evidence against:** No network, credential harvesting, payload download, or shell-evaluation behavior is present in the lifecycle helper., The package content is Kubernetes skill documentation; the observed impact is the automatic broad agent-skill mutation. ## Affected versions and remediation This report applies to k8s-agent-skills@1.10.0. - Avoid installing k8s-agent-skills@1.10.0. 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.
