Yahoo! yesterday announced that they'd been hacked leaving a sizeable number of their users with potentially compromised accounts. Hacking group D33DS has claimed responsibility with Yahoo! confirming that one of its older files from the Yahoo! Contributor Network that contains around 450,000 Yahoo! and other company's user names and passwords, was compromised.
Yahoo! insists that only five percent of the passwords included in this file were still valid however they have responded by resetting passwords and notifying affected users which include those with yahoo.com, gmail.com and aol.com email addresses.
BBC News discusses this in further detail here.
