A spokeswoman for UK Anti-Doping said "There is simply no justifiable reason why athletes’ private medical information should continue to be used as the basis of a sustained attack on the anti-doping movement. All of the British athletes involved have followed a robust process and have been given permission to take medications based on medical need.
"Stakeholders should be assured that we take IT security incredibly seriously and whilst no organisation is immune from cyber-attack we continue to monitor our systems and update them as necessary.
"We strongly condemn the sustained and continued attacks on clean sport, and those who strive to protect it, in an attempt to discredit the anti-doping authorities. It is completely counterintuitive as the only purpose these attacks serve is to distract anti-doping organisations from their core work, putting clean athletes and clean sport at risk."
