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:** 2.0.15 - **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. Source inspection confirms global postinstall setup that installs recurring jobs, including a default daily updater. This is package-aligned setup and does not show a concrete attack, so it warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-08T16:14:43.560Z - **Finished:** 2026-10-08T16:16:04.820Z - **Download time:** 512 ms - **Static scan time:** 122 ms - **AI review time:** 80624 ms - **Total time:** 81260 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 configures the package and can create recurring user-level jobs. The jobs support account polling and health checks; the inspected source does not establish a malicious attack. - **Trigger:** A global npm installation on a supported platform, unless skipped by the environment or opt-out flag. - **Impact:** Persistent scheduled activity and package updates in the user account; no confirmed credential theft or external attack surface was established. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:16:04.820Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches install.sh, which configures recurring account checks and health jobs; macOS also enables a daily updater by default. - **Rationale:** Source inspection confirms global postinstall setup that installs recurring jobs, including a default daily updater. This is package-aligned setup and does not show a concrete attack, so it warrants a warning rather than a block. - **Files touched:** package.json, scripts/postinstall.mjs, install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs a postinstall script., The hook skips local and CI installs but automatically invokes the installer for global installs., The installer adds recurring account checks and health jobs to the user crontab., The installer enables a daily update job by default on macOS. - **Evidence against:** The hook has explicit skip conditions, and the scheduled jobs invoke this package’s account-management commands., The selector validates JSON input and calls its account-selection logic; no attack behavior was identified in the inspected excerpt. ## Affected versions and remediation This report applies to claude-multiacc@2.0.15. - Review the evidence and your use of claude-multiacc@2.0.15 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.
