It’s their forward facing site that just presents crap like contact links and the most general info about the CIA.
It was a DDOS attack. It’s not like they actually gained access to anything, besides causing a public facing website to be unaccessible for a while. Although the CIA might want to analyze if their threat monitoring devices need to be tuned better to deal with something like this. These clowns were still able to overwhelm it with bogus request packets.
They are really pissing on the wrong tree by doing this. You really don’t want to get the CIA and it’s resources fixed in your direction.
