Not convinced
Something doesn't add up here, why are hacktivists openly bragging about bringing down a sworn enemies website/Internet. Aren't Israel and Iran already on tenderhooks?
Would the adult thing not be to remain very,very, very quiet.
If they are truely capable of doing what they did, they could simply pass on their methods to the ShinBeit and let the ShinBeit do the dirty work.
Iran might have dictators at the top but they also some very clever people in the background. Personally I wouldn't be bragging about this.
