The Russian hackers who accessed the World Anti-Doping Agency's database of Olympians' medical records leaked more documents Monday, this time involving Spanish tennis player Rafael Nadal, British runner Mo Farah, and American gymnast Laurie Hernandez, among others, reports Sports Illustrated.
This is the fourth data dump by the hackers, which included data of 26 athletes from Argentina, Belgium, Burundi, Canada, Denmark, France, Britain, Hungary, Spain and the U.S., reports Reuters.
The first information leak came last week, when the group of Russian hackers claimed responsibility for breaking into the database and leaking medical information of tennis player Serena Williams and gymnast Simone Biles, both Americans.
The World Anti-Doping Agency believes the attacks are hackers' attempt at retaliation for investigations exposing state-sponsored doping in Russia, according to Reuters.
