Washington (CNN) Russian state-sponsored hackers have targeted state and local governments and in at least two instances have successfully stolen data, US national security officials said Thursday, one day after the top US intelligence officials said Russia and Iran obtained voter registration information. There is concern that Russia similarly accessed data but it is not clear what its intention is, the source said. Russian state-sponsored attackers, meanwhile, have attempted to penetrate "dozens" of state and local government and aviation networks, the warnings said. The Treasury Department did not issue any new sanctions Thursday against Russia, which also had been cited by the intelligence community the day prior. CORRECTION: This story and headline have been corrected to specify that Russian hackers targeted data from state and local governments, but unlike Wednesday's FBI announcement the officials did not say it was election data.
