Subsequent Claude and Codex invocations can be routed through package-controlled shims; recurring jobs can maintain and update that control surface. - **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:** 2.0.31 - **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 npm install automatically changes shell command resolution for Claude and Codex and creates persistent scheduled jobs. The package also configures a hard-coded remote sync target that can receive Claude setup tokens during account synchronization. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-12T18:01:24.926Z - **Finished:** 2026-09-12T18:02:52.710Z - **Download time:** 502 ms - **Static scan time:** 268 ms - **AI review time:** 87013 ms - **Total time:** 87784 ms The recorded confidence comes from the underlying analysis.

The package also configures a hard-coded remote sync target that can receive Claude setup tokens during account synchronization. - **Trigger:** Global npm installation or update triggers postinstall. - **Impact:** Subsequent Claude and Codex invocations can be routed through package-controlled shims; recurring jobs can maintain and update that control surface. - **Evidence paths:** package.json, scripts/postinstall.mjs, lib/install\_actions.sh, install.sh, lib/common.sh, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-12T18:02:52.710Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** PATH shadowing, scheduled persistence, and remote token synchronization. - **Attack narrative:** On global installation, postinstall runs install.sh without an interactive setup command. The installer edits shell startup files to place its Claude and Codex shims first on PATH, creates scheduled jobs including daily self-update, and initializes account pools. The package hard-codes an SSH destination and its sync logic transfers Claude setup-token files there. This is an unconsented lifecycle takeover of broad AI-agent command surfaces with persistence. - **Rationale:** The package's global postinstall automatically installs PATH-shadowing Claude and Codex shims plus persistent schedulers. Its hard-coded remote sync target and setup-token transfer create a concrete credential-exposure path after account setup. - **Files touched:** ~/.zshenv, ~/.zprofile, ~/.zshrc, ~/.bashrc, ~/.bash\_profile, ~/.profile, /etc/profile.d/claude-multiacc.sh, /usr/local/bin/claude, /usr/local/bin/codex, ~/.claude-accounts, ~/.codex-accounts, ~/Library/LaunchAgents, crontab - **Network endpoints:** 138.197.36.107 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The install lifecycle automatically runs the installer during global npm installation., The installer prepends package shims to shell PATH configuration, intercepting Claude and Codex commands., It installs recurring launchd or cron jobs and enables a daily self-update job., It has a hard-coded SSH sync destination and code to copy setup tokens to it., The sync routine copies each account's server token to the configured remote server. - **Evidence against:** The lifecycle script skips local installs and CI environments., Codex refresh credentials are not copied by its sync routine. ## Affected versions and remediation This report applies to claude-multiacc@2.0.31. - Avoid installing claude-multiacc@2.0.31. 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.
