A global npm install automatically mutates multiple user-level AI-agent control surfaces. It installs hooks, instructions, MCP servers, runtime code, and plugins across unrelated hosts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-11T20:00:41.883Z - **Finished:** 2026-08-11T20:02:13.039Z - **Download time:** 1539 ms - **Static scan time:** 16382 ms - **AI review time:** 73233 ms - **Total time:** 91156 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically mutates multiple user-level AI-agent control surfaces. It installs hooks, instructions, MCP servers, runtime code, and plugins across unrelated hosts. - **Trigger:** npm install -g devcodex (postinstall) - **Impact:** Unconsented persistent control of Copilot, Claude, Codex, Gemini, Grok, and Cursor user configuration. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js, scripts/lib/global-host-config-transaction.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T20:02:13.039Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent configuration and hook/MCP/plugin deployment - **Attack narrative:** The package’s postinstall runs automatically on global installation and calls its global host configuration routine. That routine targets six AI-agent products and writes user-home instructions, hooks, MCP configuration, runtime files, and Grok/Cursor plugins; Codex specifically receives AGENTS.md, hooks.json, and MCP server entries. Although it skips local workspace and CI installs and no exfiltration was confirmed, the automatic global-install mutation of broad foreign AI-agent control surfaces is concrete and unconsented. - **Rationale:** Source inspection confirms a postinstall-triggered, broad user-level AI-agent control-surface mutation. This meets the blocking policy regardless of the absence of confirmed network exfiltration. - **Files touched:** $HOME/.copilot, $HOME/.claude, $HOME/.codex/AGENTS.md, $HOME/.codex/hooks.json, $HOME/.codex/config.toml, $HOME/.gemini, $HOME/.grok, $HOME/.cursor, $HOME/.agents ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global-install postinstall executes global host configuration., Default targets cover Copilot, Claude, Codex, Gemini, Grok, and Cursor., It writes user-level instructions, hooks, MCP settings, plugins, and runtime files., Codex configuration receives managed MCP servers and hooks without an explicit CLI command. - **Evidence against:** No source-confirmed credential harvesting or network exfiltration was found., Lifecycle hook skips ordinary workspace, CI, and indirect installs. ## Public findings ### 1.
