It can alter AI-agent skill control locations without an explicit user command or prompt. - **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:** 0.0.28 - **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. Installation automatically invokes an agent-skills installer. It selects global scope for global installs and project scope otherwise. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-27T02:53:48.141Z - **Finished:** 2026-09-27T02:54:35.084Z - **Download time:** 757 ms - **Static scan time:** 17 ms - **AI review time:** 46167 ms - **Total time:** 46943 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:** Installation automatically invokes an agent-skills installer. It selects global scope for global installs and project scope otherwise. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** It can alter AI-agent skill control locations without an explicit user command or prompt. - **Evidence paths:** package.json, .npm/postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-27T02:54:35.084Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches a platform-specific cio binary with the skills install command and a global or project flag. - **Attack narrative:** The package's postinstall hook resolves a platform binary and runs its skills-install command. For ordinary project installs it changes the working directory to the directory from which installation was started; for global installs it chooses global scope. Package text identifies this command as writing agent-skill locations used by Claude and open-agent tools. This is an automatic lifecycle mutation of a broad AI-agent control surface. - **Rationale:** The package performs an unconsented postinstall invocation that installs AI-agent skills at project or global scope. This meets the install-control-surface blocking rule. - **Files touched:** .claude, .agents ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers a postinstall lifecycle hook., The hook automatically runs the platform binary's skills-install command with global or project scope and targets the installing project's directory., The package text identifies the command as installing agent skills into Claude and open-agent skill locations. ## Affected versions and remediation This report applies to @customerio/cli@0.0.28. - Avoid installing @customerio/cli@0.0.28. 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.
