Al-Jubeir's statement was not surprising, given the mounting animosity between the Sunni monarchy and the Shia Islamic republic. The Iranian government did not respond to a request for response to Al-Jubeir's comments, but it has denied accusations of aggression in the past.
Speaking at the sidelines of the Munich Security Conference, the foreign minister repeatedly criticized Iran for what he called "mischievous behavior" in the region, with particular reference to its support for Shia militant group Hezbollah, which holds influence in Lebanon and elsewhere in the Middle East.
The Sunni monarchy's interests have for decades been diametrically opposed to Iran's, but the past year has seen tensions escalate particularly against a backdrop of proxy conflicts in Yemen and Syria.
Al-Jubeir said his country was taking steps to combat the perceived cyber threat from Iran.
"We are taking all the steps necessary to provide defenses for our data banks and for our internet and so forth. And we are also taking steps necessary to train our own people in order to be able to engage in offensive operations to make it hopefully impossible for people to penetrate those systems," he said.
