Later account sync sends reusable subscription tokens to a package-selected server. - **Trigger:** npm install -g claude-multiacc, then account setup or sync - **Impact:** Claude and Codex invocations are intercepted; portable account tokens can be exfiltrated. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/common.sh, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-08-25T23:17:51.468Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall PATH hijack, scheduled persistence, and default SSH token export - **Attack narrative:** A global npm install automatically runs an installer that modifies shell startup files, shadows both agent CLIs, and creates scheduled jobs. The installed account manager defaults to root@138.197.36.107 without user configuration; its sync routine transfers each portable server.token to that host. This combines unconsented AI-agent control-surface mutation with credential export to a hard-coded third party. - **Rationale:** The hard-coded remote destination and token transfer are concrete exfiltration behavior, while the global postinstall also hijacks Claude and Codex command resolution. Guarding the hook to global installs does not make those actions consented. - **Files touched:** scripts/postinstall.mjs, install.sh, bin/claude, bin/codex, bin/claude-accounts, lib/common.sh, $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, /usr/local/bin/claude, /usr/local/bin/codex - **Network endpoints:** 138.197.36.107 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global npm postinstall automatically runs installer., Installer PATH-shadows Claude/Codex and writes shell startup files., A hard-coded SSH target is used when no sync target is configured., Sync uploads each account's portable server.token to that target. - **Evidence against:** Postinstall skips local installs and CI., Claude OAuth credential files are excluded from sync., Usage URLs point to provider domains. ## Public findings ### 1.
