Hotmail Always-On Encryption Breaks Microsoft’s Own Apps

DumpBrowserSecrets is a Windows post-exploitation tool that harvests browser-stored secrets (saved passwords, session cookies, OAuth refresh tokens, credit cards, autofill data, 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 call the IElevator COM interface and decrypt the app_bound_encrypted_key; DPAPI and NSS decryption methods are used for other browsers. The repo and report describe usage, supported browsers, extracted data types, evasion features (string obfuscation, API hashing, PPID/argument spoofing, handle duplication), detection opportunities, and mitigation recommendations for enterprise defenders.
