Yahoo! Mail Accounts Hacked

Late Thursday night, Yahoo! acknowledged that hackers using third-party malicious software were able to log in to multiple Yahoo! Mail accounts, and that the affected accounts must now create new passwords. Yahoo! said that it believes the hackers were using credentials obtained during the hacking of another company to access Yahoo! accounts, as people often use the same password on multiple accounts. Yahoo! declined, however, to say exactly how many accounts were compromised.
