BookFab uses a clever hack to avoid the need to crack the latest KFX DRM. It obtains the customer's credentials and Kindle for PC registration info and then communicates with Amazon's servers pretending to be the latest version of Kindle for PC. However unlike the real app, when it requests a book for download it indicates that it only supports older KFX DRM that has been cracked since 2021. Surprisingly that actually works. Amazon supplies the files that make up the book and then BookFab uses included code from DeDRM and my KFX Input plugin to do the rest of the work.
This is what I suspected. Thank you for the investigating and the warning. Although I would stop buying from Amazon rather than paying for DRM removal.
