DumpBrowserSecrets is a post-exploitation credential-harvesting tool that extracts passwords, cookies, OAuth tokens, credit card data, autofill and history from Chrome, Edge, Brave, Opera variants, Vivaldi, and Firefox by bypassing App-Bound Encryption (via IElevator DLL injection into a headless Chromium) or using DPAPI/NSS methods; it includes operational evasion features and is intended for red-team assumed-breach testing but poses a high-risk capability for real-world credential theft and cloud account takeover.
