Russian military intelligence attempted to cyber-attack a U.S. voting software supplier and more than 100 local election officials in the days leading up to the 2016 presidential election, The Intercept reported Monday. According to an NSA document ... Russian military intelligence cyber-attacked a U.S. voting software supplier, using information gained in that attack to "launch a voter registration-themed spear-phishing campaign targeting U.S. local government organizations. Russian General Staff Main Intelligence Directorate actors executed cyber espionage operations against a named U.S. company in August 2016, evidently to obtain information on elections-related software and hardware solutions," the document states. The operation gave the hackers "persistent access" to the targeted computers, allowing them to "survey the victims for items of interest." But Pamela Smith, president of election integrity watchdog Verified Voting, said the hacking might have kept some Americans from voting. "If someone has access to a state voter database, they can take malicious action by modifying or removing information," she told The Intercept. "This could affect whether someone has the ability to cast a regular ballot or be required to cast a 'provisional' ballot - which ... may mean the voter has to jump through certain hoops such as proving their information to the election official before their eligibility is affirmed."
