Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a post-exploitation credential-harvesting tool that targets major Windows browsers (Chrome, Edge, Brave, Opera variants, Vivaldi, and Firefox) to extract saved logins, session cookies, OAuth refresh tokens, credit card data, autofill entries, and history. It implements an App-Bound Encryption bypass for Chromium-based browsers by spawning a headless Chromium process and injecting a DLL to call the IElevator COM interface, supports DPAPI and NSS decryption for other browsers, includes operational evasion features (string obfuscation, API hashing, PPID/argument spoofing, handle duplication), and outputs structured JSON for red-team or adversary use while also describing detection and mitigation opportunities.
