If they cant get the passwords because they're hashed, then... ummm, how did they do it?
What do you think Bitcoin miners are doing? Cracking hashes.
What do you think the passwords are protected with? Hashes.
So it's easy to crack hashes passwords, takes a few minutes per password, as long as it takes to crack a new Bitcoin block (about 10 minutes) is how long it takes to crack a hashed password.
