Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A global install automatically alters shell command resolution and creates persistent scheduled jobs. When an account token is created and synced, the package sends it to a hard-coded root SSH host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T16:45:08.535Z - **Finished:** 2026-09-08T16:46:29.011Z - **Download time:** 257 ms - **Static scan time:** 206 ms - **AI review time:** 80011 ms - **Total time:** 80476 ms The recorded confidence comes from the underlying analysis.

When an account token is created and synced, the package sends it to a hard-coded root SSH host. - **Trigger:** Global npm installation activates the installer; later account synchronization sends server tokens. - **Impact:** Claude subscription setup tokens can be disclosed to the hard-coded remote server, while future package releases are installed automatically. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/common.sh, bin/claude-accounts - **Review source:** ai\_review - **Reviewed:** 2026-09-08T16:46:29.011Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** PATH hijacking, persistence, remote token synchronization, and unattended self-update. - **Attack narrative:** On global installation, postinstall invokes an installer that places package shims ahead of existing Claude and Codex commands and creates persistent jobs. The installer initializes account synchronization with a hard-coded root SSH destination. Once a Claude account has a server token and synchronization runs, the token is copied to that destination. A scheduled self-update can later install a newer package release without an interactive update command. - **Rationale:** This is concrete credential exfiltration to a package-controlled hard-coded server combined with automatic command interception and persistence. The guarded global-install condition does not remove the risk. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, $ACC\_ROOT/$id/server.token, $ACC\_ROOT/update.log - **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 block:** The package runs a postinstall hook that invokes its installer during global npm installs., The installer prepends its own bin directory to shell startup files and installs recurring launchd or cron jobs., A hard-coded root SSH destination is used as the default sync server., The Claude sync routine copies each account's server token to that remote server., Scheduled jobs can repeatedly fetch and install the latest package release. - **Evidence against:** The postinstall hook skips local, CI, Windows, and explicitly disabled installs., The Codex sync path does not copy auth.json refresh-token files. ## Affected versions and remediation This report applies to claude-multiacc@2.0.25. - Avoid installing claude-multiacc@2.0.25. 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.
