I think there is nothing extra, as phrutis is too stupid to develop any software. He is just a regular russian thief, he takes someone's software, copy/paste to his repo, changes name and sells like his own.
In that case he took WifSolveCuda, hardcoded ranges and removed printing data to the screen.
WIF is obviously fake, known for months, but as long as russians waste their time and electricity on that, I am fine.
