Matasano has just been hacked. They are one of the top security web sites with an amazing group of professionals.
This is the screenshot:
I don’t know what happened, but it probably wasn’t a 0-day as people are saying. If anti-sec really had a 0-day they would have hacked a lot more web sites… My guess: it was either a weak password from some of their web designers or a web application bug. Let’s hope to hear soon from them on what happened.
