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 postinstall hook can configure a package-owned CLI shim during global installation, creating an extension lifecycle risk. Its gates and the inspected command-shim behavior do not establish a malicious attack, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-10-08T16:17:17.455Z - **Finished:** 2026-10-08T16:17:43.890Z - **Download time:** 505 ms - **Static scan time:** 255 ms - **AI review time:** 25673 ms - **Total time:** 26435 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 automatically configure this package as a command shim. This is a package-owned CLI setup behavior; the inspected evidence does not establish a separate malicious attack. - **Trigger:** Installing globally with npm when CI and the opt-out gate are absent. - **Impact:** The shim can intercept Claude or Codex commands and route them through this package's account-selection behavior. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/codex - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:17:43.890Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script invokes install.sh, whose setup puts the package shim first on PATH. - **Rationale:** The postinstall hook can configure a package-owned CLI shim during global installation, creating an extension lifecycle risk. Its gates and the inspected command-shim behavior do not establish a malicious attack, so warn rather than block. - **Files touched:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/codex ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest registers a postinstall hook., Postinstall runs setup only for global installs, with skip gates for CI, local installs, and an opt-out variable., The installer places the package shim first on PATH, enabling it to handle Claude or Codex commands., The package describes the setup as a PATH shim and addon; the reviewed evidence does not establish a separate malicious action. - **Evidence against:** The Codex shim locates and delegates to the real Codex binary., The install-time setup is gated and can be skipped. ## Affected versions and remediation This report applies to claude-multiacc@2.0.34. - Review the evidence and your use of claude-multiacc@2.0.34 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.
