You may want to rephrase the question to avoid confusion.
Personal computers got hacked everyday if they don't have adequate security/protection.
The hacker may/will install key-loggers program to record your key strokes and steal your user id and password.
Someone has reported their PC got hacked and can't log into DNF or any other account from different registrars.
We are working with Admins to get the problem resolved now.
Thanks,
