U.S. Olympians’ data hacked

Hackers have published confidential medical data belonging to a handful of high-profile American athletes including Serena Williams and Simone Biles. WADA identified the hackers as a Russian group known as Fancy Bear, which published what are called therapeutic use exemptions, waivers that allow athletes to take banned substances on medical grounds. The data, which also included Venus Williams, was posted online Tuesday, with threats that more files would follow. Fancy Bear claimed the documents prove the athletes had broken antidoping rules.
