Last.fm is the latest tech giant to fall victim to a security breach. The music-streaming site is urging its users to change their passwords immediately. The breach comes amid a backdrop of similar breaches, including at LinkedIn where 8 million passwords may have been compromised, and at dating site eHarmony where 1.5 million passwords were harvested. Do not use the same password for everything, keep a list of every site you create a login for, and only go to the site in a new tab or window.
