A group of cyber hackers has released details claiming to show the National Surveillance Agency had been monitoring presidential websites in Iran and Russia.
Data released by the Shadow Brokers claimed the Russian Federal Nuclear Center's website was also compromised by the NSA.
The Shadow Brokers released a cache of documents, some of which carried the NSA's logo, although the security organization refused to confirm whether they were genuine.
According to Cyberscoop, a former intelligence officer said: 'The fact this is in there the way it is means these targets were definitely owned. It means a successful op, plain and simple.'
The NSA hacks included Russian internet service providers and even the office of the president for the Russian federation.
