Even though not relating to Iran, this article talks about the power the NSA has in penetrating computer data. It basically explains how no computer hardware or firmware is safe from NSA penetration and illustrates the power America has over other countries cyberspace.
The article cites leaked documents provided by whistle-blower Edward Snowden that reveal US initiatives that launched cyber warfare on Iran. The document gives analysis of Iran's quickness to learn from US cyber attacks evidenced by the attacks by Iran on Saudia Arabia.
The U.S. believes Iran may have learned it's cyberwarfare tactics from the U.S. However, rather than just replicating attacks the U.S. has imposed on Iranian cyberspace, Iran is improving their cyberweapons and are becoming more and more potent.
I found this article from 2015 to still be very relevant considering President Obama's speech and a recent push by university/techs to communicate regarding the exact threat of ISIS' cyberterrorism capabilities. The NSA reported that this means of war is parallel to that of the Cold War; leaving countries on edge since traditional human espionage is slowly becoming intertwined with "technical operations."
