Persistent changes to the agent's available instructions and tool-hook behavior extend beyond this package. - **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:** 1.0.6 - **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. LPM flags this version as an AI-agent control-surface risk. Installation automatically changes Claude's user-level control surface by installing skills and registering command hooks. These changes occur without a consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T09:40:15.779Z - **Finished:** 2026-09-30T09:41:59.063Z - **Download time:** 780 ms - **Static scan time:** 271 ms - **AI review time:** 102232 ms - **Total time:** 103284 ms The recorded confidence comes from the underlying analysis.

These changes occur without a consent prompt. - **Trigger:** npm installation with lifecycle scripts enabled. - **Impact:** Persistent changes to the agent's available instructions and tool-hook behavior extend beyond this package. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-30T09:41:59.063Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script copies skills and hook scripts into Claude directories and saves command-hook registrations in user settings. - **Attack narrative:** Installing the package activates its postinstall script, which installs skills into project and home Claude directories and registers executable hooks in home Claude settings. Runtime session checks restrict hook behavior but do not provide consent for these automatic configuration changes. The hook skip variable is an opt-out and does not stop skill installation. - **Rationale:** Inspected source proves unconsented postinstall mutation of a foreign, user-wide AI-agent control surface. This meets the supplied blocking policy despite runtime hook guards. - **Files touched:** .claude/skills, .claude/hooks, .claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs scripts/postinstall.cjs after installation., The script directly invokes skill and hook installation without a consent prompt., Skills are copied into both project and user Claude skill directories., Hook installation defaults to enabled and targets the user's Claude settings., Command hooks are registered and the modified settings are saved. - **Evidence against:** Hook execution uses session activation checks., An environment variable can skip hook installation, but skills are still installed. ## Affected versions and remediation This report applies to twintest@1.0.6. - Avoid installing twintest@1.0.6. 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.
