Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 2.0.16 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The global-only postinstall performs first-party command and scheduled-task setup that affects Claude and Codex invocation. This warrants a warning for lifecycle setup; the inspected source does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-08T16:14:28.991Z - **Finished:** 2026-10-08T16:14:55.474Z - **Download time:** 762 ms - **Static scan time:** 125 ms - **AI review time:** 25595 ms - **Total time:** 26483 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:** A global npm install automatically runs the package’s installer. It changes shell PATH configuration and creates scheduled jobs and command shims for the package’s account tools. - **Trigger:** Installing globally through npm, unless the hook is skipped by its environment checks. - **Impact:** The package gains automatic command routing and recurring execution for its own tools. The inspected behavior supports a warning for lifecycle setup, but does not establish a concrete malicious attack. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:14:55.474Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script launches install.sh, which appends package PATH entries and installs scheduled jobs; root Linux setup also creates system-wide command shims. - **Rationale:** The global-only postinstall performs first-party command and scheduled-task setup that affects Claude and Codex invocation. This warrants a warning for lifecycle setup; the inspected source does not establish malicious behavior. - **Files touched:** package.json, scripts/postinstall.mjs, install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook that starts its bundled installer on global installs., The installer adds PATH blocks to shell startup files and installs scheduled jobs., On Linux root installs, the installer creates system-wide Claude and Codex command shims. - **Evidence against:** The postinstall skips local installs, CI, Windows, and installs without npm’s global-install flag., The setup installs this package’s own account-management tools and command shims. ## Affected versions and remediation This report applies to claude-multiacc@2.0.16. - Review the evidence and your use of claude-multiacc@2.0.16 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
