The University of Georgia and the University System of Georgia are investigating whether they are victims of a Russian cyber-extortion gang’s global hack of a file-transfer program.

The Cl0p ransomware syndicate behind the hack announced last week on its dark web site that its victims, who it suggested numbered in the hundreds, had until Wednesday to get in touch to negotiate a ransom or risk having sensitive stolen data dumped online.

Known victims to date include Louisiana’s Office of Motor Vehicles, Oregon’s Department of Transportation, the Nova Scotia provincial government, British Airways, the British Broadcasting Company and the U.K. drugstore chain Boots.

The gang, among the world’s most prolific cybercrime syndicates, claimed it would delete any data stolen from governments, cities and police departments.
