Following LinkedIn, the base and Last.fm safely leaked

Last.fm, a popular social service for music preferences, was the victim of an attack that compromised databases containing user password information. It is not very clear yet, but according to unverified information, the passwords were stored in the clear as MD5 hashes (!!!) without salt (!!!!!). A curtain. Change passwords, username.
UPD 1 . Information about unsalted MD5 came from Russ Garrett, who left the company in 2009.
