A Georgia wire and cable manufacturer has filed a federal lawsuit in Atlanta after its confidential business information was taken and posted online in the wake of a ransomware attack.

The redacted complaint, filed Dec. 31 in the U.S. District Court for the Northern District of Georgia, said the unknown defendant demanded several million dollars to keep the information stolen from Southwire Co. private. The alleged hacker posted the confidential information online after Southwire refused to pay.
