LONDON (Reuters) -Russia's spy chief on Tuesday denied responsibility for the SolarWinds cyber attack but said he was "flattered" by the accusations from the United States and Britain that Russian foreign intelligence was behind such a sophisticated hack.

The United States and Britain have blamed Russia's Foreign Intelligence Service (SVR), successor to the foreign spying operations of the KGB, for the hack which compromised nine U.S. federal agencies and hundreds of private sector companies.
