Using Google to Crack Hashed Passwords
...I thought it would be interesting to find out the account password. Wordpress stores raw MD5 hashes in the user database.... As with any respectable hash function, it is believed to be computationally infeasible to discover the input of MD5 from an output. Instead, someone would have to try out all possible inputs until the correct output is discovered.
Instead, I asked Google. I found, for example, a genealogy page listing people with the surname "Anthony", and an advert for a house, signing off "Please Call for showing. Thank you, Anthony". And indeed, the MD5 hash of "Anthony" was the database entry for the attacker. I had discovered his password.
