The personal information of roughly 3.1 million Toyota customers may have been leaked following a security breach of multiple Toyota and Lexus sales subsidiaries. Unauthorized access was detected on the computing systems of Tokyo Sales Holdings, Tokyo Tokyo Motor, Tokyo Toyopet, Toyota Tokyo Corolla, Nets Toyota Tokyo, Lexus Koishikawa Sales, Jamil Shoji (Lexus Nerima), and Toyota West Tokyo. This breach comes after Australian Toyota dealers were also targeted by a cyber attack which led to multiple corporate IT systems going down on February 19.
