Bradley Wiggins and Chris Froome are among a new group of athletes to have details of substan­ces they had taken leaked by Russian hackers who broke into their drug-testing records.

Russian cyber-hackers Tsar Team (APT28), also known as Fancy Bear, have published documents which show that they have taken banned substances for which they had received a therapeutic use exemption (TUE).

Chris Froome had four TUE for prednisolone, a synthetic glucocorticoid, a derivative of cortisol. The product is used to treat a variety of inflammatory and autoimmune conditions. The Tour de France winner used it for five days in May 2013 at the Critérium du Dauphiné and seven days in April 2014 during the Tour of Romandie. The latter TUE has been widely reported but the one from 2013 Dauphiné, which Froome won, has not been. 

Bradley Wiggins had six TUEs for salbutamol.

"We condemn this criminal activity and have asked the Russian Government to do everything in their power to make it stop. Continued cyber-attacks emanating from Russia seriously undermine the work that is being carried out to rebuild a compliant anti-doping program in Russia," said Olivier Niggli, Director General, WADA. "We still believe that access to ADAMS was obtained through spear phishing of email accounts; whereby, ADAMS passwords were obtained enabling access to ADAMS account information confined to the Rio 2016 Games. We have no reason to believe that other ADAMS data has been compromised."

A TUE is a certificate which allows an athlete to take an otherwise banned substance either in or out of competition.
