Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a public post‑exploitation credential-harvesting tool for Windows that extracts saved passwords, session cookies, OAuth refresh tokens, credit card data, autofill entries, and browsing history from Chromium-based browsers (Chrome, Edge, Brave, Opera variants, Vivaldi) and Firefox. It bypasses Chrome's App‑Bound Encryption by spawning a headless Chromium process and injecting a DLL via Early Bird APC to use the IElevator COM interface, handles DPAPI and NSS encryption models, and includes operational evasion techniques (string obfuscation, API hashing, PPID/argument spoofing, handle duplication, custom SQLite parser). The report assesses red-team relevance, demonstrates high-speed credential extraction enabling cloud account takeover and lateral movement, and outlines detection opportunities (monitor IElevator calls, anomalous headless browser instantiation, non-browser reads of browser DBs) and mitigations (use external credential managers and EDR rules).
