Subsequent Claude/Codex invocations are redirected through package shims; scheduled code runs repeatedly and portable tokens can be sent to the embedded remote server. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.11 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm install automatically shadows Claude/Codex commands and creates persistent scheduled jobs. The package also embeds a remote SSH target for token sync. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-21T13:07:41.724Z - **Finished:** 2026-08-21T13:09:49.599Z - **Download time:** 761 ms - **Static scan time:** 97 ms - **AI review time:** 127016 ms - **Total time:** 127875 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically shadows Claude/Codex commands and creates persistent scheduled jobs. The package also embeds a remote SSH target for token sync. - **Trigger:** npm install -g claude-multiacc - **Impact:** Subsequent Claude/Codex invocations are redirected through package shims; scheduled code runs repeatedly and portable tokens can be sent to the embedded remote server. - **Evidence paths:** scripts/postinstall.mjs, install.sh, lib/common.sh, bin/claude-accounts, bin/claude, bin/codex - **Review source:** ai\_review - **Reviewed:** 2026-08-21T13:09:49.599Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall PATH hijacking, scheduled persistence, and token synchronization - **Attack narrative:** On global installation, postinstall invokes install.sh without an explicit setup command. The installer modifies shell startup files so its Claude and Codex shims take precedence, then installs recurring launchd or cron jobs including a daily self-update. It seeds a fixed SSH server and the sync implementation uploads portable server tokens there. This is unconsented install-time mutation of broad AI-agent command and scheduling control surfaces. - **Rationale:** The lifecycle hook performs broad, persistent Claude/Codex interception and scheduled execution on global install. Under the firewall policy, this concrete unconsented postinstall control-surface mutation warrants blocking despite package-described functionality. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, /etc/profile.d/claude-multiacc.sh, $HOME/Library/LaunchAgents/com.claude-multiacc.limits.plist, $HOME/Library/LaunchAgents/com.claude-multiacc.update.plist, user crontab, $HOME/.claude-accounts/server.token - **Network endpoints:** 138.197.36.107, https://chatgpt.com/backend-api/codex/usage, https://api.anthropic.com/api/oauth/usage, https://auth.openai.com/oauth/token, https://console.anthropic.com/v1/oauth/token ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global postinstall runs install.sh automatically., Installer prepends package shims ahead of Claude and Codex., Installer persists minute-level launchd/cron jobs and daily updates., A default remote SSH target is embedded., Sync uploads portable server tokens to that remote target. - **Evidence against:** Postinstall skips local installs, CI, Windows, and an opt-out env flag., Usage telemetry endpoints are provider-aligned., Credential sync is implemented as a named package feature. ## Public findings ### 1.
