Iran, one of the seven countries reportedly hit by the most dangerous malware discovered till date blames Israel for the attacks. Iranian cyber defense organization confirmed that the computers of high-ranking Iranian officials appear to have been penetrated by a data-mining malware called Flame.

According to The Vancouver Sun, a senior Israeli minister said the use of cyberweapons to counter Iran's nuclear plans would be "reasonable," hinting at Israel's possible involvement in unleashing the newly uncovered Flame virus.

"For anyone who sees the Iranian threat as significant, it is reasonable that he would take different steps, including these, in order to hobble it," Moshe Yaalon, the vice prime minister, told Israeli army radio yesterday, just hours after the Flame virus was discovered by Russia's Kaspersky Lab.

"Israel is blessed with being a country which is technologically rich, and these tools open up all sorts of possibilities for us," said Yaalon, who is also Israel's strategic affairs minister.
