For less than $20,000 in Bitcoins, any hacker can have access to some 617 million online account details stolen from 16 hacked websites.  Account records from this multi-gigabyte databases consist mainly of account holder names, email addresses, and passwords.

These passwords are hashed or encrypted and need to be cracked before they can be used.
