 Lauren Weinstein, our expert on the Internet. Lauren, what's going on with this thing? Yeah, so for apparently a couple of weeks now, that major provider of services to car dealers, CDK Global, has been mostly shut down due to a ransomware attack. Now, unless you're in the car business, you may never even have heard of CDK. But, yeah, they're used by something like 15,000 dealerships for payroll, finance, and a wide variety of other key functions.
