The leak of a classified NSA document confirming that Russian military intelligence interfered with the 2016 U.S. presidential race has reinforced the need to fix vulnerabilities in America’s voting infrastructure before the next election cycle, say experts who expressed dismay over the reported intricacy of the Kremlin’s campaign. According to the leaked report, which was dated May 5 and published yesterday by The Intercept, the Russian General Staff Main Intelligence Directorate, or GRU, launched a spoofing attack against an unnamed electronic voting vendor, in order to get access to that company’s data and internal systems. Next, the GRU hackers (often referred to as the APT Fancy Bear) sent various government employees spear phishing emails that appeared to be from this e-voting vendor, but in actuality contained attachments that infected machines with malware. … J. Alex Halderman, director of the Center for Computer Security & Society at the University of Michigan’s College of Engineering, said that Russia’s spearphishing plot “raises an enormous number of questions about how far they got [and] if other vendors were attacked that haven’t been detected or announced yet, about what they were trying to do, and about whether they succeeded” in their ultimate objective.
