Of note on the sheer size of this hack. The normal Internet download speed of Iranian is 11.8 megabits per second.[2] To download 50 terabytes of data from the Foreign Affairs Ministry of Iran at this speed, would take over 392 days or over a year of uninterrupted download time, and Iran’s Internet frequent drops, is throttled by the government, and experiences regular government-induced blackouts. Based on these numbers, such an attack highly likely occurred from direct access to the data.
