World Anti-Doping Agency (WADA) has confirmed the authenticity of the third batch of documents published by the Fancy Bears hacker group. The confirmation was reported on WADA’s official website.

On Friday, the hacking group released a third batch of documents from the World Anti-Doping Agency (WADA), naming additional athletes from Europe who used the banned substances.

The data includes 11 athletes from five countries, including the United Kingdom, Denmark, Australia, Spain and Germany. The 9 athletes who were mentioned in the released documents won medals during the Rio Olympics 2016.

In the list, there were four Britons — two gold and two silver medalists, three Australians — one gold medal and two silver medalists. Other athletes who used doping include swimmer from Denmark and Spain, German tennis player and German shooter.

The hackers received their data from ADAMS (Anti-Doping Administration and Systems Management). According to WADA, all the athletes were taking banned drugs in connection with Therapeutic Use Exemptions (TUE).

“In short, athletes may have illnesses or conditions that require a particular substance or method that appears on WADA’s List of Prohibited Substances and Methods. In such instances, they may be granted a TUE, which gives them permission to take a substance or use a method,” the statement on WASA’s website read.

WADA has stated that it is ready for new security breaches and publications. According to a statement released on their website, the agency is consulting international law enforcement agencies and experts in the field of cyber security.

Kremlin spokesman Dmitry Peskov refuted allegations of WADA suggesting that Russia is behind these leaks.

Peskov said that the West is attempting to distract from the issue by baselessly accusing the Russian government of being behind the WADA security breaches.

"It can be stated with all certainty that there is no involvement of the official Moscow, [Russian] government or special services in such actions. This is completely ruled out," he told reporters.

"These unfounded allegations…do not honor any organization, if they are not backed by something substantial. I do not know whether those who came out with such statements possess any substantial arguments," Peskov said.

Earlier this week, the hacking group leaked alleged WADA documents showing that the agency allowed US tennis players Serena and Venus Williams, as well as Olympic gold-winning gymnast Simone Biles and basketball star Elena Delle Donne, to take banned substances for "therapeutic" purposes.
