Several auto dealers across the U.S. have had to halt sales after a cyberattack on Wednesday.

Software company CDK Global was the victim of a cyberattack on Wednesday, meaning all dealers who rely on them had to halt sales for the time being. 

Following Wednesday's attack, Automotive News reports that a second cyberattack happened into the evening so systems remained shut down into Thursday.

According to CDK's website, the company serves tens of thousands of car dealerships including some in the Mahoning Valley.

The exact amount of dealerships in the Valley that use CDK is unclear, but at least three dealers have confirmed with 21 News that they have been affected by this.
