The United States carried out a secret cyber operation against Iran in the wake of the Sept. 14 attacks on Saudi Arabia’s oil facilities, which Washington and Riyadh blame on Tehran, two U.S. officials have told Reuters. The officials, who spoke on condition of anonymity, said the operation took place in late September and took aim at Tehran’s ability to spread “propaganda.”

One of the officials said the strike affected physical hardware, but did not provide further details.
The strike appears more limited than other such operations against Iran this year after the downing of an American drone in June and an alleged attack by Iran’s Revolutionary Guards on oil tankers in the Gulf in May.
The United States, Saudi Arabia, Britain, France and Germany have publicly blamed the Sept. 14 attack on Iran, which denied involvement in the strike. The Iran-aligned Houthi militant group in Yemen claimed responsibility.
The Pentagon declined to comment about the cyber strike.
“As a matter of policy and for operational security, we do not discuss cyberspace operations, intelligence, or planning,” said Pentagon spokeswoman Elissa Smith.
