Claude and Codex invocations can be redirected through the package, which rotates subscription accounts and can transfer portable tokens to a configured server. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.0.30 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global install silently modifies shell command resolution and creates persistent scheduled jobs. Those jobs repeatedly invoke account-management code and can automatically reinstall this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-12T09:21:53.301Z - **Finished:** 2026-09-12T09:23:13.781Z - **Download time:** 253 ms - **Static scan time:** 265 ms - **AI review time:** 79961 ms - **Total time:** 80480 ms The recorded confidence comes from the underlying analysis.

Those jobs repeatedly invoke account-management code and can automatically reinstall this package. - **Trigger:** npm install -g claude-multiacc, followed by shell startup or scheduled job execution. - **Impact:** Claude and Codex invocations can be redirected through the package, which rotates subscription accounts and can transfer portable tokens to a configured server. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/codex, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:23:13.781Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall PATH shadowing, scheduler persistence, and automated package self-update. - **Attack narrative:** A global npm installation runs a postinstall hook that launches install.sh. The installer modifies shell startup files so its Claude and Codex shims take precedence, then creates launchd or cron jobs that refresh accounts and perform daily self-updates. The shims rotate subscription identities for normal AI CLI commands, and the account tool can copy portable tokens to a remote target. This is an unconsented persistent interception of foreign AI command surfaces. - **Rationale:** The package combines an automatic install hook with persistent PATH shadowing of Claude and Codex, scheduled execution, and automated self-reinstallation. This is a concrete broad AI-agent control-surface mutation rather than a passive CLI utility. - **Files touched:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/claude, bin/codex, bin/claude-accounts, $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, $HOME/Library/LaunchAgents, user crontab - **Network endpoints:** https://console.anthropic.com/v1/oauth/token, https://auth.openai.com/oauth/token ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs the installer during global npm installation., The installer prepends package shims to shell startup files, replacing normal Claude and Codex command resolution., It installs recurring launchd or cron jobs, including a daily silent self-update., The shims deliberately run Claude and Codex under selected subscription accounts, creating a broad AI-command interception surface., The package can send portable account tokens to a configured remote server. - **Evidence against:** No manifest self-dependency is present., Observed OAuth endpoints are Anthropic and OpenAI hosts rather than an unrelated collection host., The cited test file is ordinary Python source, not a hidden executable payload. ## Affected versions and remediation This report applies to claude-multiacc@2.0.30. - Avoid installing claude-multiacc@2.0.30. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
