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.
That's not quite accurate. Miners are tweaking one value in a block of data in order to find any password WITHIN THE DIFFICULTY. Finding a hash that is lower than a set value is far easier than finding a very specific existing password. Essentially, cracking the password would be solving the highest difficulty block possible. (Also, Miners are working on SHA256, much harder to crack than simple MD5...)
