DumpBrowserSecrets is a publicly documented post-exploitation tool that harvests browser-stored credentials (cookies, saved logins, OAuth refresh tokens, credit cards, autofill, history, bookmarks) from major Chromium-based browsers and Firefox; it includes an App-Bound Encryption bypass for Chrome/Edge/Brave via IElevator COM with Early Bird APC DLL injection, DPAPI handling for Opera/Vivaldi, NSS decryption for Firefox, and operational evasion features aimed at red-team use but readily abusable by adversaries.
