It also schedules unattended updates that reinstall the package. - **Trigger:** Running npm install -g claude-multiacc or a scheduled cron or launchd job afterward. - **Impact:** Subsequent claude and codex commands can be intercepted and run through package-controlled account and credential logic; future releases are installed automatically. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/codex, bin/codex-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-12T20:04:19.705Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall PATH shadowing, command shims, persistence, and automatic self-update. - **Attack narrative:** On global installation, npm automatically invokes install.sh. That installer places the package bin directory ahead of normal command paths, can create system-wide claude and codex symlinks, and installs recurring jobs. The shims intercept the original AI command names. A daily scheduled task checks npm and installs claude-multiacc@latest, re-triggering postinstall and preserving the control chain without a new explicit setup command. - **Rationale:** This is an unconsented postinstall mutation of a broad AI-agent control surface: it shadows Claude and Codex commands, persists scheduled jobs, and self-updates. The global-install guard does not remove the automatic lifecycle behavior or its control over later command execution. - **Files touched:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, bin/codex, bin/codex-accounts, $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, /etc/profile.d/claude-multiacc.sh, /usr/local/bin/claude, /usr/local/bin/codex, $HOME/Library/LaunchAgents/com.claude-multiacc.\*.plist, crontab ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall hook that automatically starts its installer during global npm installation., The installer rewrites shell startup files so its bin directory precedes the existing PATH., It replaces the commands named claude and codex with package shims, including system-wide symlinks when run as root., It creates recurring launchd or cron jobs, including a daily job that installs the latest package release., The Codex shim intercepts normal codex invocations and executes the real binary only after applying its account-pool behavior. - **Evidence against:** The postinstall hook skips local installs, CI, Windows, and an explicit opt-out environment setting., No hard-coded third-party exfiltration endpoint was found in the inspected installation path. ## Affected versions and remediation This report applies to claude-multiacc@2.0.32. - Avoid installing claude-multiacc@2.0.32. 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.
