Future Claude and Codex invocations and scheduled jobs run package-controlled code, including automatic updates. - **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:** 2.0.5 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global install changes shell command resolution so the package intercepts Claude and Codex invocations, then installs background jobs. This is an unconsented lifecycle mutation of a broad AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T16:43:45.554Z - **Finished:** 2026-08-28T16:46:20.215Z - **Download time:** 519 ms - **Static scan time:** 113 ms - **AI review time:** 154027 ms - **Total time:** 154661 ms ## Security analysis ### Published attack-surface review - **Summary:** A global install changes shell command resolution so the package intercepts Claude and Codex invocations, then installs background jobs. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Trigger:** A non-CI global npm installation on macOS or Linux. - **Impact:** Future Claude and Codex invocations and scheduled jobs run package-controlled code, including automatic updates. - **Evidence paths:** package.json, scripts/postinstall.mjs, install.sh, lib/common.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-28T16:46:20.215Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall runs an installer that shadows agent commands and adds persistent schedulers. - **Attack narrative:** On a global npm install, the postinstall hook runs install.sh without a separate setup command. The installer modifies shell startup files to place its own Claude and Codex shims first, installs recurring launchd or cron jobs, and schedules daily package updates. When run as root, it redirects system command paths to its shims. This gives the package persistent control over broad AI-agent command execution. - **Rationale:** The guarded global trigger does not make the lifecycle mutation consented: installation automatically rewrites broad shell and agent command surfaces and adds persistence. This meets the policy threshold for malicious install-hook abuse. - **Files touched:** $HOME/.zshenv, $HOME/.zprofile, $HOME/.zshrc, $HOME/.bashrc, $HOME/Library/LaunchAgents/com.claude-multiacc\*.plist, /usr/local/bin/claude, /usr/local/bin/codex, $HOME/.claude-accounts, $HOME/.codex-accounts - **Network endpoints:** 138.197.36.107, https://api.anthropic.com/api/oauth/usage, https://chatgpt.com/backend-api/codex/usage ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global npm installation automatically launches the shell installer., The installer prepends package shims to shell startup files, intercepting Claude and Codex commands., It creates recurring background jobs and enables a daily self-update job., Root installs replace the system Claude and Codex command paths with package symlinks., A hard-coded SSH host is the default account-pool sync target. - **Evidence against:** The lifecycle hook skips local, CI, and Windows installs., Provider usage endpoints are consistent with the package's stated account-pool feature. ## Public findings ### 1.
