Future Claude and Codex invocations can be redirected through package-controlled code; scheduled jobs also perform account operations and automatic updates. - **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:** 2.0.28 - **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 installation automatically persists shims and recurring jobs that intercept Claude and Codex commands. It changes broad AI-agent command control surfaces before any separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T21:57:39.549Z - **Finished:** 2026-09-12T21:58:43.017Z - **Download time:** 510 ms - **Static scan time:** 263 ms - **AI review time:** 62694 ms - **Total time:** 63468 ms The recorded confidence comes from the underlying analysis.

It changes broad AI-agent command control surfaces before any separate setup command. - **Trigger:** npm install -g claude-multiacc - **Impact:** Future Claude and Codex invocations can be redirected through package-controlled code; scheduled jobs also perform account operations and automatic updates. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh, lib/install\_actions.sh, lib/common.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:58:43.017Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches a PATH-shadowing installer that creates persistent scheduled jobs and command shims. - **Attack narrative:** On global installation, npm runs the package postinstall, which invokes install.sh without a separate setup action. The installer prepends its directory to shell PATH files, can install /usr/local/bin Claude and Codex shims, and creates recurring launchd or cron jobs, including automatic updates. Those changes make later AI-agent commands run package-controlled wrappers and persist after the install command ends. - **Rationale:** This is an automatic postinstall mutation of broad, foreign Claude and Codex command control surfaces, with persistence and automatic updating. The global-install guard does not provide separate consent for these changes. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bash\_profile, $HOME/.bashrc, $HOME/Library/LaunchAgents, user crontab, /etc/profile.d/claude-multiacc.sh, /usr/local/bin/claude, /usr/local/bin/codex - **Network endpoints:** root@138.197.36.107, https://chatgpt.com/backend-api/codex/usage, https://api.anthropic.com/api/oauth/usage ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall automatically runs the installer during global installation., The installer persists scheduled Claude and Codex jobs through launchd or crontab, including daily self-updates., The installer rewrites shell startup files to place its shims first in PATH and can replace the system Codex and Claude command paths., The package defaults account-pool syncing to a remote SSH host and queries provider usage endpoints. - **Evidence against:** The postinstall skips local installs, CI, Windows, and an explicit opt-out., No hidden binary payload or arbitrary code download was found in the inspected lifecycle path. ## Affected versions and remediation This report applies to claude-multiacc@2.0.28. - Avoid installing claude-multiacc@2.0.28. 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.
