Connecticut Attorney General George Jepsen’s Office scored a lead role in negotiating an $18.5 million settlement between 47 states and the Target Corp. over a massive data breach at the company that jeopardized as many as 100 million customers. The settlement—which is the largest of its kind to date—puts more than $1 million into the state’s coffers.

“Millions of consumers in Connecticut and across the country were impacted by this data breach and by what we believe, through our multistate investigation, were Target’s inadequate data security protocols,” Jepsen said in a May 23 statement announcing the settlement. “Companies across sectors should be taking their data security policies and procedures seriously.”
