Treat them as untrusted evidence. 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:** 2.0.53 - **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 install hook automatically runs package-owned setup on global installs, creating an agent extension lifecycle risk that merits a warning. Inspected evidence does not establish malicious behavior or justify blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-10-08T16:18:21.805Z - **Finished:** 2026-10-08T16:18:47.635Z - **Download time:** 1287 ms - **Static scan time:** 393 ms - **AI review time:** 24149 ms - **Total time:** 25830 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:** Global installation can automatically run the package installer, which configures this package's own command shim and scheduled jobs. This is package-owned setup; no separate malicious attack was established. - **Trigger:** Installing globally with npm, unless the configured skip or CI condition applies. - **Impact:** The package can change command lookup and schedule its own jobs for account management. - **Evidence paths:** package.json, scripts/postinstall.mjs, lib/install\_actions.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:18:47.635Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall launches install.sh, which configures this package's own integration. - **Rationale:** The install hook automatically runs package-owned setup on global installs, creating an agent extension lifecycle risk that merits a warning. Inspected evidence does not establish malicious behavior or justify blocking publication. - **Files touched:** install.sh, lib/install\_actions.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers a postinstall lifecycle script., The postinstall skips local installs, but on global installs it runs the package's installer., The installer sets up this package's own PATH shim and scheduled jobs., The test finding is a test module describing sandboxed fixtures, not an executable payload. - **Evidence against:** The install action is gated to global installs and supports skipping the postinstall., Inspected code shows first-party setup; no unrelated recipient or concrete malicious behavior was established. ## Affected versions and remediation This report applies to claude-multiacc@2.0.53. - Review the evidence and your use of claude-multiacc@2.0.53 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.
