Manufacturing was the No. 1 OT industry hit with ransomware last year, according to Dragos report. Manufacturing surpassed financial services as the most-attacked vertical (23.2%) investigated by IBM X-Force last year. Ransomware accounted for 23% of those attacks; the majority of attacks were on IT networks in the industrial sector, with just a few on their OT networks. Last year Dragos also discovered three “new” threat groups, Kostovite, Petrovite, and Erythrite.”]
