DumpBrowserSecrets is a tool for extracting sensitive information from modern browsers, specifically Chromium-based and Gecko-based ones like Chrome, Edge, Firefox, Opera, and Vivaldi. It pulls data such as refresh tokens, cookies, saved credentials, credit card information, browsing history, and bookmarks. The tool consists of two main components: an executable file and a DLL. The executable, DumpBrowserSecrets.exe, can create a headless Chromium process, extract decryption keys, and parse browser databases to retrieve stored data. It utilizes techniques like DLL injection and data parsing from SQLite databases. The DLL, DllExtractChromiumSecrets.dll, operates within Chromium browsers to decrypt App-Bound encryption keys. It retrieves necessary values from the browser's Local State file and sends them back to the executable for data extraction. This version improves upon its predecessor, DumpChromeSecrets, by consolidating extraction operations within the executable, limiting the DLL's role to key retrieval. Notable features include compile-time string obfuscation to avoid detection and duplication handling to bypass file locks from running browsers. The tool also allows users to specify extraction options, such as the target browser and the maximum number of entries per category. Encrypted output is supported for offline decryption, requiring a user-defined signature. The article lists specific database paths and formats for storing cookies, logins, credit card data, and more for each supported browser, detailing their encryption models.
