Whilst hacking can affect many devices, accounts or even websites, it is very likely that you might have got hacked from a different source. Although there is a small chance in getting hacked through Feral Heart, I would look somewhere else as I highly doubt that someone would go through all the effort of downloading Feral Heart, paying money for a special program etc and invading your computer.
As I stated before, yes hackers can hack almost anything, even the president's laptop, phone or whatever he may hold. But to use Feral Heart as a proxy would be almost unwise.
Trust me, you'd be better off checking all your emails first for spam, phishing**...etc as those could potentially lead to a hack.
**an email that contains some letter etc asking you to give them your information which may or may not be personal. They may ask for your name, username, password etc
