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 with App-Bound Encryption, Opera/Vivaldi with DPAPI, and Firefox using NSS). It bypasses Chrome’s App-Bound Encryption by spawning a headless Chromium instance and injecting a DLL via Early Bird APC to call the IElevator COM interface, includes evasion techniques (string obfuscation, API hashing, PPID/argument spoofing, handle duplication), outputs structured JSON, and is positioned for red-team/assumed-breach use while also representing an operational risk if abused by adversaries.
