No user interaction or target selection is required. - **Trigger:** npm global installation runs the postinstall hook. - **Impact:** The package can alter a foreign AI-agent configuration and introduce externally sourced tool capabilities during dependency installation. - **Evidence paths:** package.json, postinstall.js, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-28T01:30:50.500Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the shell installer with automatic confirmation. The installer defaults to Claude Code, creates a home-directory agent location, and registers MCP servers, including one supplied with existing provider credentials. - **Attack narrative:** Installing this package globally triggers postinstall. That hook silently launches the installer with automatic confirmation. The installer defaults to Claude Code, creates agent files under the user home directory, and configures user-scope MCP servers. It also passes existing OpenAI or Anthropic API-key environment variables into a browser-use MCP registration. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle chain modifies a foreign AI-agent environment and installs MCP capabilities without an explicit setup command or target choice. This meets the install-control-surface blocking rule. - **Files touched:** $HOME/.claude, $HOME/.claude/agents/neocortex, $HOME/.neocortex - **Network endpoints:** https://mcp.context7.com/mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares an npm postinstall lifecycle hook., On global installation, the lifecycle handler automatically runs its installer., The installer is invoked with automatic confirmation and no project prompt., When no target is chosen, the installer defaults to Claude Code., The installer creates a user Claude agent directory., The installer adds user-scope Claude MCP integrations and forwards existing AI-provider environment credentials to one integration. ## Affected versions and remediation This report applies to @ornexus/neocortex@4.60.51. - Avoid installing @ornexus/neocortex@4.60.51. 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.
