Iran’s state railway operator was hit with a cyberattack that was disruptive and – somewhat unusually – also playful. Attackers programmed screens at train stations to show a number for travelers to call for more information about the problems. The phone number, 64411, is for the office of Iran’s supreme leader, Ali Khamenei. Security firm SentinelOne says it has recovered components of the malware used in the attack. It turns out to be a previously unseen type of “wiper” malware designed to erase data and brick computers.”]
