there are insider tips that the following forum is linked to Iranian intel : rce.ir it is a fairly new forum . it has a specific section regarding cyber war and there is a presentation centered on APT against nations and how the whole thing works . it has a military style tone so i can say it wouldn't be built by people who work on their own or companies . i can translate it but its long . in short it says Irans only real adversary is U.S and U.S only means a series of contractors . file is attached . in another topic in the forum they mention the drone downed by a university in U.S to demonstrate to homeland security it is possible , then the topic's author puts a clip of Iranian UAVs taking films from American Navy in Persian Gulf and flying around them "undetectably" and "identifying" the flying objects from the boat ( F-16 , F-18 , etc ) and at the end it says : wait around here when we reveal how the RQ-170 downed .
