<br>How Does It Work
This project is an improved version of DumpChromeSecrets, and similarly consists of two components:
- Executable (
DumpBrowserSecrets.exe)
Creates a headless Chromium process, injects the DLL via Early Bird APC injection, and receives extracted decryption keys. These keys are either App-Bound (extracted from Chrome, Brave, and Microsoft Edge) or DPAPI keys (used by Opera, Opera GX, and Vivaldi). Once the required keys have been recovered, this executable parses the browser's SQLite databases and JSON files on disk and decrypts the stored data, including credentials, cookies, tokens, and other browsing data.
Additionally, when targeting non-Chromium-based browsers (e.g., Firefox), DumpBrowserSecrets.exe handles all the required steps for data extraction and decryption (without DLL-Injection).
- DLL (
DllExtractChromiumSecrets.dll)
Runs inside Chromium browsers to decrypt the App-Bound encryption key using the IElevator COM interface. It leverages the IElevator COM interface to decrypt the App-Bound encryption key and retrieves the decrypted values of app_bound_encrypted_key and encrypted_key from the targeted browser's Local State file. These values are then returned to the executable, which performs all extraction operations.
<br>[!NOTE] Unlike the DumpChromeSecrets project, this implementation performs all browser data extraction in the
DumpBrowserSecrets.exeexecutable, while the DLL is limited to retrieving encryption keys from Chromium-based browsers.
Features
Below are some of the most notable features provided:
- Compile-time string obfuscation and API hashing to evade static analysis.
- PPID & argument spoofing via
NtCreateUserProcesswith manual CSRSS registration. - Custom SQLite3 file format parser (
SQLoot), replacing sqlite-amalgamation in > v1.1.1. - Handle duplication to bypass file locks held by running browsers.
- Encrypted output packs for offline decryption using a user-defined signature.
