A global npm install automatically launches a setup flow that installs a Neocortex profile into Claude Code. That profile requests bypass-permission mode; no credential theft or payload download was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-27T21:40:14.539Z - **Finished:** 2026-08-27T21:41:34.096Z - **Download time:** 1270 ms - **Static scan time:** 1712 ms - **AI review time:** 76575 ms - **Total time:** 79557 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically launches a setup flow that installs a Neocortex profile into Claude Code. That profile requests bypass-permission mode; no credential theft or payload download was confirmed. - **Trigger:** Global installation of the package runs postinstall. - **Impact:** It changes the user's AI-agent configuration and can cause the Neocortex profile to run with bypassed permissions. - **Evidence paths:** package.json, postinstall.js, install.sh, targets-stubs/claude-code/neocortex.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T21:41:34.096Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic first-party Claude Code extension setup with elevated agent permissions. - **Rationale:** This is not proven malicious, but an install-time automatic AI-agent extension with bypass-permission mode warrants a warning. The observed setup is first-party and package-scoped, so it does not meet the blocking threshold. - **Files touched:** $HOME/.claude/agents/neocortex/, $HOME/.neocortex/config.json - **Network endpoints:** https://api.neocortex.sh/health ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the installer for global installs., The installer defaults to the Claude Code target and creates a Neocortex agent under the user's Claude configuration., The installed Claude agent requests bypass-permission mode., The lifecycle installer deletes selected legacy configuration artifacts and configures a remote thin client. - **Evidence against:** The automatic setup is for a package-named Neocortex extension rather than a broad arbitrary agent takeover., The reviewed lifecycle code has no credential harvesting or secret upload path., The only confirmed lifecycle network request is a version health check to the package service. ## Public findings ### 1.
