Consumers aren’t the only ones suing over the Equifax data breach: Small businesses, including a law firm and a credit union, want to recoup financial losses tied to the massive cyberattack.

Summit Credit Union in Madison, Wisconsin, has brought a class action on behalf of all credit unions that have had to reimburse customers for fraudulent charges and forgo fees due to the breach, which has impacted 143 million people. Robins Kaplan brought that suit on Sept. 11 in federal court in Georgia.
