Group targets US athletes; Russia says government was not involved

The World Anti-Doping Agency on Tuesday slammed Russian hackers who breached its database and published confidential records of US Olympic gymnast Simone Biles and tennis stars Venus and Serena Williams.

WADA said in a statement that the Russian cyber-espionage group Tsar Team (APT28), also known as Fancy Bears, had broken into its Anti-Doping Administration and Management System (ADAMS) database.
