The Flame computer virus which is threatening to bring countries to a standstill is too sophisticated to have been created anywhere other than the U.S., it was claimed today.
As the United Nations prepares to issue its ‘most serious warning’ to guard against the superbug, cyber experts said it carried all the markings of a U.S. espionage operation.
Specifically, they have pointed the finger at the highly secretive National Security Agency.
UN computer security chief Marco Obiso moved to highlight the gravity of the situation after it emerged the bug had been used to hack into computers in Iran.
The sophisticated spyware – said to be about 100 times the size of most malicious software – also hacked other machines in the Middle East, including Sudan, Saudi Arabia, Lebanon and Egypt.
‘It was (the) U.S,’ one anonymous official told NBC News , although they conceded that they had no first-hand knowledge about how the virus operates or how it was fed into Iranian computers.
