The U.S. Department of Justice said Thursday that two U.S.-based law firms were among the victims of a “complex transnational organized cyber-crime network” that has been taken down, thanks to a law enforcement effort involving cooperation between U.S. and European officials. 

The DOJ’s statement did not specify the names of the entities, only that one was a law firm in Washington, D.C., and another was a law office in Wellesley, Massachusetts.
