The skill required to carry out attacks on this scale has convinced United States government officials and security researchers that they are the work of Iran, most likely in retaliation for economic sanctions and online attacks by the United States.
Before today did you know that Iranians had mad hacker skillz that no one else in the world had? That if there's some sort of major online attack it must be the Iranians, because it couldn't be anybody else?
Obviously I have no idea. But this is hilarious.
