The package takes control of broad AI CLI execution and can persistently run account and update operations; its sync feature transfers portable account tokens to the configured remote server. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.0.27 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm install automatically modifies shell command resolution so this package shadows Claude and Codex. It also installs recurring scheduled jobs and can send pooled account tokens to a hard-coded external SSH destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-12T22:47:55.706Z - **Finished:** 2026-09-12T22:49:25.944Z - **Download time:** 503 ms - **Static scan time:** 147 ms - **AI review time:** 89587 ms - **Total time:** 90238 ms The recorded confidence comes from the underlying analysis.

It also installs recurring scheduled jobs and can send pooled account tokens to a hard-coded external SSH destination. - **Trigger:** Global npm installation, then ordinary claude or codex commands and scheduled jobs. - **Impact:** The package takes control of broad AI CLI execution and can persistently run account and update operations; its sync feature transfers portable account tokens to the configured remote server. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh, lib/common.sh, bin/claude-accounts, bin/codex - **Review source:** ai\_review - **Reviewed:** 2026-09-12T22:49:25.944Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time PATH hijacking, persistence, account switching, and token synchronization. - **Attack narrative:** Installing globally invokes install.sh without a separate setup command. The installer puts package shims ahead of existing commands, writes scheduler entries, and enables daily updates. The codex shim changes CODEX\_HOME before executing the genuine CLI, redirecting normal use through package-managed account state. The package also defaults its account-pool server to root@138.197.36.107 and copies portable server tokens there when synchronizing. - **Rationale:** This is an unconsented postinstall mutation of the broad Claude and Codex command surface, with persistence and a hard-coded remote token-sync destination. The readable source confirms the behavior directly. - **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, $ACC\_ROOT/acct-NN/server.token - **Network endpoints:** root@138.197.36.107, https://chatgpt.com/backend-api/codex/usage, https://auth.openai.com/oauth/token, https://api.anthropic.com/api/oauth/usage ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall lifecycle hook., On global install, the hook automatically runs the installer to configure PATH shims and scheduled jobs., The installer places its bin directory first in shell startup files and replaces the codex command with its shim., The installer creates recurring launchd or cron jobs, including a daily self-update., The default configuration names an external root SSH server, and the sync routine copies account tokens there., The codex shim selects an account directory, sets CODEX\_HOME, and executes the real Codex binary under that account. - **Evidence against:** No opaque executable payload was found; shipped executables are readable shell, Node, and Python source., The observed HTTPS endpoints are vendor authentication and usage endpoints, but they do not offset the install-time command hijack and persistence. ## Affected versions and remediation This report applies to claude-multiacc@2.0.27. - Avoid installing claude-multiacc@2.0.27. 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.
