(Undated) — The California DMV is reporting the personal information of some drivers may have been leaked. The agency says a contractor they use to verify vehicle registration addresses was hit with a ransomware attack earlier in the month. Information the DMV provided to the company over the past 20 months may have been compromised in the attack. This includes names, addresses, license plate numbers and vehicle identification numbers. An investigation is underway to determine if the information has been used for criminal purposes.
