A cyber attack that derailed websites of Iran’s transport ministry and its national railway system earlier this month, causing widespread disruptions in train services, was the result of a never-before-seen reusable wiper malware called “Meteor.”
The campaign — dubbed “MeteorExpress” — has not been linked to any previously identified threat group or to additional attacks, making it the first incident involving the deployment of this malware, according to researchers from Iranian antivirus firm Amn Pardaz and SentinelOne. Meteor is believed to have been in the works over the past three years.
