A government agency in charge of fighting sabotage said today in its website, paydarymelli.Ir, that the attack hit the networks of the Oil Ministry and the National Iranian Oil Company yesterday.
The website said experts were able to block the cyberattack and that the hackers were unable to get access to classified information due to its security system.
Iran periodically reports the discovery of viruses and other malicious programs in government, nuclear, oil and industrial networks, blaming Israel and the United States. In May, Iran shut down part of its oil facilities because of another such cyberattack.
