I develop this tool called Brave User Data Backup and can be used to get data or take advantage of BAT.
Go to the user computer that has Brave Browser installed.
1 - Make sure you close all Brave windows.
2 - Execute my “Brave User Data Backup.exe” and let compress the User Data.
3 - Copy BraveBackup.rar from the desktop to your storage device.
On your computer
1 - Execute and extract brave portable “brave-portable-win64-1.25.68-74-setup.exe”.
2 - Open BraveBackup.rar with winrar.
3 - Navigate to Users > Your Profile Name > AppData > Local > BraveSoftware > Brave-Browser.
4 - Extract the folder User Data to your desktop.
5 - Rename the folder to data and copy to your Brave Browser Portable folder (next to brave-portable.exe).
6 - Open brave-portable.exe and configure your wallet to cash out.
Didn’t scan to avoid sharing the files but should have a few false positives. Use on a vmware or sandbox.
