Four Olympic champions from Rio 2016 were among 11 high-profile stars from Great Britain, Spain, Denmark, Australia and Germany targeted today by the hacking group Fancy Bears'.

They nclude two leading female British stars, four-time Olympic cycling champion Laura Trott and double boxing gold medal winner Nicola Adams. 

"We keep on exposing the information about the athletes who got WADA permission for doping," the group wrote on their website today.

All the information, however, appears to relate to legally obtained therapeutic use exemptions (TUE) granted by various sporting bodies in order to treat medical condition. 

There is no suggestion of wrongdoing by the athletes.

WADA have already blamed a Russian group and has approached the country's Government to assist it in its investigation.

"This is an unacceptable and outrageous breach of medical confidentiality that attempts to smear innocent athletes who have not committed any doping offence," Bach told insidethegames today.

"In some cases, it is also a breach of confidentiality for athletes whose cases have not yet been finalised.

"The IOC fully support the actions taken by WADA to deal with the leak, including the measures that are being taken to bring this activity to an end with the help of IT experts and in requesting assistance from the Russian authorities. 

"The IOC Medical, Legal and IT departments will continue to communicate closely with WADA to investigate the background to this serious issue.

"I have informed the WADA President, Sir Craig Reedie, that the IOC will also assist WADA in any way required, including communicating with the Russian authorities, to underline the seriousness of the issue and request all possible assistance to stop the hackers."

Although similar to messages from other anti-doping bodies, this marks a significant sign of solidarity from the IOC given their perceived reluctance to stand alongside WADA and strongly criticise Russia following allegations earlier this year of state-sponsored doping in the country.

Russian Sports Minister Vitaly Mutko has also vowed to help with the investigation into the cyber-attacks, although he has claimed the Government has nothing to do with it. 

On Tuesday (September 14) the same hackers released details of of TUEs belonging to America's four-time Olympic gymnastics gold medallist Simone Biles, basketball player Elena Delle Donne and tennis superstars Serena and Venus Williams.

A second raft of leaked data the following day included British Tour de France winners Sir Bradley Wiggins and Chris Froome.

The latest series of leaks includes two other Britons, 200 metres individual medley swimming silver medallist Siobhan-Marie O'Connor and Olivia Carnegie-Brown, also a silver medallist as part of the women's rowing eight.

Three Australians were targeted: singles sculls rowing champion Kim Brennan, quad sculls silver medallist Alexander Belonogoff and team pursuit cycling silver medallist Jack Bobridge.

They were joined by two swimmers, women's 4x100m medley relay bronze medallist Jeanette Ottesen of Denmark and 200m butterfly champion Mireia Belmonte of Spain.

German tennis player Laura Siegemund, winner of the mixed doubles US Open title last month, and her fellow countryman and 10m air rifle shooter Julian Justus.

Of these, Bobridge has publicly spoken about how he suffers from rheumatoid arthritis are requires medication for his hands and wrists.

He received permission to take glucocorticoids and prednisolone, both used to treat inflammatory conditions.

Adams, an under 51kg boxing champion at London 2012 and Rio 2016, received a "retrospective approval for one-time emergency use" of asthma-drug methylprednisolone in February this year.

O'Connor, who suffers from ulcerative colitis, has received permission for prednisolone throughout her career.

Criticim of the hacks has also been echoed today by the Institute of National Anti-Doping Organisations (iNADO).

"The criminal cyber-attacks on the World Anti-Doping Agency and release of private medical information are despicable: using athletes and their personal data in an attempt to destabilise anti-doping and weaken clean sport is beyond criticism," said the organisation's chief executive Joseph de Pencier.

"We stand behind WADA. 

"We appreciate WADA’s swift response. 

"We echo its call to Russian authorities to take all necessary measures to find the perpetrators and to prevent more criminal acts of the same sort."
