Yulia Stepanova said she fears for her life and has been forced to move after hackers tried to find her location.

The World Anti-Doping Agency (WADA) confirmed that its online doping management account had been illegally accessed. Stepanova said she had moved her family to another location after the hack.Stepanova said that the only reason somebody would hack an ADAMS account is to find out your exact location.

"We decided it was safer to relocate If something happens to us then you should know that it is not an accident."

Stepanova angered Tsar Putin when her whistleblowing cost more than 100 Russians their place at the Rio Games. She has been in hiding in the United States with her husband Vitaly, a former Russian anti-doping official, after giving evidence that the Russian government for years facilitated widespread cheating across nearly all Olympic sports.

Vitaly Stepanov said he did not know who had hacked his wife's account but said the couple were being watched by Russian authorities.
