A Russia-linked hacker group called “Fancy Bears” released a statement on Wednesday claiming to have leaked emails and documents that demonstrate violations of anti-doping rules, just two weeks before Winter Olympics 2018.

“The obtained documents of the International Luge Federation (FIL) show the violations of the principles of fair play: widespread TUE approvals, missed anti-doping tests and the double standards approach towards guilty athletes,” read the report.

This is the same group that was implicated in the 2016 Democratic National Committee (DNC) hack, and is also known by the names “Pawn Storm” or “APT 28”.

This is believed to be in response to Russia’s ban from the 2018 Winter Olympics following the controversy in the 2016 games where the same group is believed to have been responsible for the hack that leaked sensitive athlete data stolen from the World Anti-Doping Agency (WADA), which too was in response to the organization’s recommendation to ban Russian athletes from the 2016 games in Rio over allegations of state-sponsored doping.

The hacking group’s “About Us” on their website reads, “We are going to tell you how Olympic medals are won. We hacked World Anti-Doping Agency databases and we were shocked with what we saw.”
