Iranian oil ministry’s computer network came under attack from hackers and a computer virus. Iranian oil terminal on Kharg Island was disconnected from the Internet as part of the response to the attacks. Officials said they were disconnecting the oil terminals and possibly some other installations in an effort to combat the virus. Email systems associated with the targets were also pulled offline. Iranian Students News Agency said that the virus, called “wiper” by its creator, had successfully erased information on hard disks at the Oil Ministry’s headquarters.
