Some of the hacked Fancy Bears medical documents were altered, say World Anti-Doping Agency

WADA say the hackers may have doctored or fabricated some of the medical documents of athletes.

The World Anti-Doping Agency has indicated the hacker group Fancy Bears may have doctored or fabricated some of the medical documents of athletes that it has released.

WADA released an update on Wednesday into its own cyber security investigation, reporting that a Rio 2016 section of its anti-doping administration and management system (ADAMS) was accessed after a 'spear phishing' attack.
