Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a post-exploitation credential-harvesting tool that extracts saved passwords, session cookies, OAuth refresh tokens, credit card data, autofill entries and browsing history from major browsers (Chrome, Edge, Brave, Opera, Opera GX, Vivaldi, and Firefox) on Windows. It bypasses Chrome's App-Bound Encryption by spawning a headless Chromium process and injecting a DLL to use the IElevator COM interface, handles DPAPI and NSS decryption for other browsers, includes evasion techniques (string obfuscation, API hashing, PPID/argument spoofing, Early Bird APC injection), outputs structured JSON, and is framed as a red-team tool useful for testing credential exposure and EDR detection capabilities.
