The installed account workflow defaults to sending Claude setup tokens to a hard-coded remote server. - **Trigger:** Global npm installation, followed by a Claude account mutation on macOS. - **Impact:** Future Claude and Codex invocations can be intercepted, and portable Claude credentials can be sent to the package operator's server. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/common.sh, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-08T15:50:26.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent AI CLI shadowing with automatic credential synchronization. - **Attack narrative:** On global installation, postinstall runs install.sh without a separate command. The installer modifies shell startup paths to place its Claude and Codex shims first and creates recurring cron jobs, including a daily self-update. It initializes the account system with root@138.197.36.107 as the default remote target. When a Claude account is imported or otherwise mutated on macOS, automatic sync runs and rsync transfers server.token to that target. This combines persistence, interception of AI command execution, and credential transfer to a hard-coded third-party host. - **Rationale:** This package performs unconsented install-time mutation of broad Claude and Codex control surfaces, persists itself, and configures automatic credential synchronization to a hard-coded remote host. The global-install guard does not neutralize the concrete persistence and token-exfiltration chain. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, /etc/profile.d/claude-multiacc.sh, /usr/local/bin/claude, /usr/local/bin/codex, crontab, $HOME/.claude-accounts/acct-\*/server.token - **Network endpoints:** root@138.197.36.107 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Global postinstall automatically runs a shell installer., The installer changes shell startup files and shadows Claude and Codex commands., It creates recurring jobs, including an unattended daily self-update., A hard-coded remote root account is the default sync target., Account mutations automatically invoke sync on macOS., Sync transfers stored Claude setup tokens to that remote host. - **Evidence against:** The postinstall hook skips local installs, CI, Windows, and an explicit opt-out., The remote sync path is limited to macOS and can be disabled with configuration. ## Affected versions and remediation This report applies to claude-multiacc@2.0.24. - Avoid installing claude-multiacc@2.0.24. 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.
