Personal information from potentially three-and-a-half million customers of the Oregon DMV could be affected. ODOT says it immediately shut down the system. They're still in the process of gathering information and analyzing their system to determine what files were affected. They're advising DMV customers to monitor their credit reports for signs of fraudulent activity.
