Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a Windows post-exploitation credential-harvesting tool that extracts saved passwords, session cookies, OAuth refresh tokens, credit card data, autofill entries, history and bookmarks from major browsers (Chrome, Edge, Brave, Opera, Opera GX, Vivaldi, and Firefox). It implements an App‑Bound Encryption bypass for Chromium-based browsers by spawning a headless Chromium process and injecting a DLL via Early Bird APC to call the IElevator COM interface and decrypt the app_bound_encrypted_key, uses DPAPI or NSS where applicable, outputs structured JSON, and includes multiple evasion features intended to reduce EDR detection in red team or offensive scenarios.
