Eleven law firms filed with a Minnesota court this week to ask for class-action certification over Target's 2013 data breach.

The document called Target's payment card security prior to the breach “lackadaisical,” and said it directly contributed to its breach. “The evidence already available to date, reveals that both before and during the breach, Target maintained substandard cybersecurity practices, which allowed the inception and caused it to spiral from a controllable event with minimal losses into one of the largest data security breaches in United States history,” the motion stated.

The law firms represented four banks and a credit union as their lead plaintiffs. 

Writing that this one case is “vastly superior” to having “thousands of financial institutions” go through the same questions against Target, the lawyers argued in the motion that their clients constitute a class, and the case should continue as a class-action suit.
