After a cyberattack at CDK Global caused the shutdown of computer systems at auto dealers nationwide, the company is now working to restore operations. CDK, which provides software to car dealerships, was hit with back-to-back cyberattacks, prompting a shutdown on Wednesday. A group claiming to be the hackers is asking for a large ransom. While efforts are in progress to recover services, CDK anticipates it will take several days to complete the process. Auto dealers like AutoNation and Lithia Motors have reported disruptions that could affect their business. Some dealerships have resorted to using paper methods to continue operations. CDK, a leading provider of cloud-based software to dealerships, is working to fully restore its systems. The cybercrime group behind the attack is reportedly demanding millions in ransom, although CDK's response to this demand is still uncertain.
