AOL CEO Tim Armstrong said that Yahoo did the best they could when it came to the data breach that exposed the information of 500 million users. In an on-stage interview at Advertising Week, Armstrong said: "Security and data is going to be something that goes on for hundreds of years probably in the future, so we are at the beginning of that stage. I think Yahoo has tried to do the best job they can. There's nobody at Yahoo who wanted the situation to happen the way it did."
