Israel was behind the nationwide cyberattack on Iran’s fuel system which crippled the country’s gas stations last month, according to a report citing US officials. It marked an escalation of the conflict between the two nations.

Iran’s fuel distribution network ground to a halt on October 26 after a cyberattack targeted the system used by motorists to purchase petrol with government-issued cards. At the time, Iran accused an unspecified “state actor” of attempting to stoke “public anger.”

Citing two US defense officials speaking on condition of anonymity, the New York Times reported that the intrusion has been attributed to Israel following confidential intelligence assessments.

Following the attack on the fuel network, the country’s Oil Ministry feared that hackers had gained access to the government’s systems. This potentially allowed them to steal data that could show how Iran manages to breach international sanctions, according to the NYT. (RT)
