CookieGhost

CookieGhost is a cross-browser Chromium cookie extractor for educational and forensic use. It safely copies browser cookies from Chrome, Brave, Edge, Opera, and Opera GX, then relaunches the browser to avoid user disruption. All cookies are exported in Firefox-compatible .txt format.

⚠️ For ethical use only. Intended for cybersecurity research, red team exercises, and educational labs with explicit user consent.

How It Works

1. Process Kill
   Target browser processes (like chrome.exe) are force-closed to avoid locked DB access.

2. Cookie Backup
   The SQLite Cookies database is copied to a temporary file.

3. CDP Launch
   The browser is restarted with --remote-debugging-port, in headless and sandbox-disabled mode.

4. Cookie Fetching
   Via WebSocket and Chrome DevTools Protocol, cookies are dumped from memory.

5. Firefox Export
   Output is formatted for compatibility with Firefox-style .txt importers.

6. Cleanup
   Temp files are deleted and the original browser is relaunched (optional).
