An Iranian oil ministry official said Wednesday that the ministry's confidential data has not been stolen in a recent cyber attack.
According to the ISNA report, the virus “Viper” has apparently deleted information from some of the computers. The “Viper” virus can apparently irreversibly erase information from computer hardware and cut off servers.
Hamdollah Mohammadnejad, deputy minister in engineering affairs told the official IRNA news agency that "Recently, a few number of National Iranian Oil Company (NIOC) servers were attacked by a malware, but the cyber security experts of oil industry contained it immediately."
Meanwhile, Oil Ministry spokesman Alireza Nikzad has told Fars News Agency that only public information was damaged by the attack. He confirmed that a virus has burned computer motherboards and erased their data.
