Scheduled processing can contact a package-chosen default SSH destination. - **Trigger:** npm install -g claude-multiacc - **Impact:** Future Claude and Codex invocations can be routed through package shims; recurring jobs can update the package and send account-pool state to the configured remote host. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, lib/common.sh, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-12T17:18:31.869Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall persistence, PATH shim takeover, scheduled self-update, and remote state distribution. - **Attack narrative:** On global installation, the postinstall hook launches the installer without an explicit setup command. The installer changes shell startup PATH order so its Claude and Codex shims run first, creates scheduled launchd or cron jobs, and enables daily package updates. It seeds a default root SSH server and scheduled limits processing starts a detached distribution process. This is persistent, unconsented control of broad AI-agent command surfaces with a recurring remote-update path. - **Rationale:** This package combines an automatic install lifecycle with broad AI-agent command interception, persistence, a default remote target, and automatic self-updating. These are concrete install-hook abuse behaviors rather than a user-invoked setup utility. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, $HOME/Library/LaunchAgents, crontab, /etc/profile.d/claude-multiacc.sh, /usr/local/bin/claude, /usr/local/bin/codex, $HOME/.claude-accounts, $HOME/.codex-accounts - **Network endpoints:** 138.197.36.107, https://api.anthropic.com/api/oauth/usage, https://chatgpt.com/backend-api/codex/usage ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** A global npm install automatically runs the installer., The installer prepends its shims to shell startup files, replacing normal Claude and Codex command resolution., It installs recurring launchd or cron jobs, including an automatic daily self-update., A default root SSH destination is embedded and used to initialise account-pool manifests., Scheduled limits processing detaches a background distribution process that transfers state to the configured destination., The updater installs the latest release of this same package, re-triggering its lifecycle hook. - **Evidence against:** The flagged test selector is ordinary readable Python test code, not a hidden executable payload. ## Affected versions and remediation This report applies to claude-multiacc@2.0.29. - Avoid installing claude-multiacc@2.0.29. 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.
