Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a post‑exploitation credential‑harvesting tool for Windows that extracts passwords, session cookies, OAuth refresh tokens, credit card data, autofill entries and browsing history from major Chromium‑based browsers (Chrome, Edge, Brave, Opera, Vivaldi) and Firefox. It bypasses Chrome’s App‑Bound Encryption by spawning a headless Chromium process and injecting a DLL to leverage the IElevator COM interface, supports DPAPI/NSS decryption for other browsers, includes operational evasion features, and writes structured JSON output for red‑team or attacker use.
