Russian hackers have acquired and posted the private drug-testing files of four U.S. athletes from the 2016 Olympic, including gymnastics champion Simone Biles.
The World Anti-Doping Agency confirmed on Sept. 13 that a group of hackers known as Fancy Bear illegally hacked its database of medical files of athletes from the Olympic games in Rio, but has not confirmed whether the files posted by the group were authentic.
Russian athletes were banned from the Rio Olympics and Paralympics after the discovery of widespread doping among the Russian team during drug tests by WADA.
The hackers said they were going public with the information gathered on the athletes, blaming their successes on illegal doping.
The website alleges that Biles tested positive in August 2016 after methylphenidate was detected in her tests. The drug is sold under various names, including Ritalin, and is commonly used as a treatment for ADHD.
In addition, the website accuses Serena Williams of using painkillers and anti-inflammatories, but there has been no indication that this is accurate.
Biles responded to the attacks on Twitter:
“I have ADHD and have taken medicine for it since I was a kid. Please know, I believe in clean sport, have always followed the rules, and will continue to do so as fair play is critical to sport and is very important to me.”
WADA Director General Olivier Niggli said in a statement to NBC News that WADA is taking the hacks very seriously and cooperating with all law enforcement agencies.
