I used the graphic above since the mouth is wide open, you know like it's spilling secrets. In case you haven't heard, that is exactly what Yahoo did yesterday. The mega search company announced that a hacking group got inside and took off with about half a million passwords.
I did a little research and found a pretty good FAQ about the whole thing on Cnet. I highly recommend reading it.
Rather than provide the info here, I'll just supply the link. Reading this is worth your time if you are a Yahoo user!
Oh, and here is Yahoo's official statement on the situation.
At Yahoo we take security very seriously and invest heavily in protective measures to ensure the security of our users and their data across all our products. We confirm that an older file from Yahoo Contributor Network (previously Associated Content) containing approximately 450,000 Yahoo and other company users names and passwords was compromised yesterday, July 11. Of these, less than 5 percent of the Yahoo accounts had valid passwords. We are taking immediate action by fixing the vulnerability that led to the disclosure of this data, changing the passwords of the affected Yahoo users and notifying the companies whose users' accounts may have been compromised. We apologize to all affected users. We encourage users to change their passwords on a regular basis and also familiarize themselves with our online safety tips at security.yahoo.com.
