Everything You Need To Know About Web Shells

DumpBrowserSecrets is a Windows post-exploitation tool that harvests browser-stored secrets (passwords, cookies, OAuth refresh tokens, credit cards, autofill, history, bookmarks) from Chromium-based browsers and Firefox. It bypasses Chrome's App-Bound Encryption by spawning a headless Chromium process and injecting a DLL to call the IElevator COM interface, retrieves DPAPI or NSS-protected keys for other browsers, and includes evasion techniques (string obfuscation, API hashing, PPID/argument spoofing, Early Bird APC injection). The tool outputs structured JSON for red-team use, enables rapid cloud account/session takeover, and the report describes detection opportunities and mitigations.
