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:** 2.0.3 - **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 postinstall launches installer behavior that can add command shims and scheduled maintenance, creating a meaningful agent CLI lifecycle risk. The reviewed code supports the package’s account-pooling purpose and provides no concrete evidence of malicious activity. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-08T16:16:03.102Z - **Finished:** 2026-10-08T16:16:42.786Z - **Download time:** 506 ms - **Static scan time:** 117 ms - **AI review time:** 39060 ms - **Total time:** 39684 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 can run setup that installs shims for Claude and Codex command names and schedules account maintenance. - **Trigger:** Global npm installation, unless CI or the skip variable is set. - **Impact:** The package can intercept those CLI invocations and run recurring maintenance; inspected evidence did not establish credential exfiltration or other malicious behavior. - **Evidence paths:** scripts/postinstall.mjs, install.sh, bin/claude - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:16:42.786Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes the package installer, which can create command shims and scheduled account checks. - **Rationale:** The global postinstall launches installer behavior that can add command shims and scheduled maintenance, creating a meaningful agent CLI lifecycle risk. The reviewed code supports the package’s account-pooling purpose and provides no concrete evidence of malicious activity. - **Files touched:** /usr/local/bin/claude ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall script., On global installs, postinstall invokes the package installer; that installer can replace command lookup with package shims and add scheduled account checks., The \`claude\` shim is designed to shadow and dispatch the real CLI, a package-aligned but meaningful command interception capability. - **Evidence against:** The postinstall skips local and CI installs and supports an explicit skip variable., The selector test file contains ordinary unit-test cases, and the selector entrypoint processes JSON input without shell execution. ## Affected versions and remediation This report applies to claude-multiacc@2.0.3. - Review the evidence and your use of claude-multiacc@2.0.3 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.
