Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a post-exploitation credential-harvesting tool that extracts saved credentials, session cookies, OAuth refresh tokens, credit card data, autofill entries, and history from major browsers (Chrome/Brave/Edge, Opera variants, Vivaldi, Firefox). It implements an App‑Bound Encryption bypass for Chromium-based browsers by spawning a headless Chromium process and injecting a DLL (Early Bird APC) to use the IElevator COM interface to decrypt keys, handles DPAPI and NSS decryption for other browsers, includes evasion features (string obfuscation, API hashing, PPID/argument spoofing, handle duplication, custom SQLite parser), outputs structured JSON, and includes detection and mitigation recommendations for defenders.
