Yahoo has revealed a second separate breach that involves over 1,000,000,000 accounts… that’s right, a one followed by nine zeros! The breach of security has lead to the release of most of their user’s names, telephone numbers, dates of birth and other personal information. As all Flickr accounts are tied to Yahoo accounts the breach affects many Flickr users as well.
If you aren’t going to delete your account then at least change your password. It is likely Yahoo and Flickr will force you to do this anyway.
