I’m calling it that the email provider gets a lawsuit from a company that lost critical data and would have decided to pay the ransom. I’m not sure I agree with that, just wouldn’t be surprised in the least if it happens. Anything to do with ransomware is awful really.
Ideally this sort of action could poke a big hole in the “business model” of ransomware. If they can’t get paid no sense developing. That said I doubt it’ll be much of a deterrent for future attacks.
