Firstly, a quick refresher on the 2016 story, and why the GRU group is being attributed. During the Democratic National Convention (DNC) that took place in the 2016 election year, two Russian hacking groups launched email phishing attacks against officials (according to an article by the Guardian). In particular, the methods of the second group involved phishing victims for their gmail login credentials, via a false security alert email; it was later determined that the second group was Fancy Bear.
In terms of the Burisma hack, Area 1 focuses on a few factors; one in particular being the methods used. According to The New York Times, attackers used phishing emails to try and steal login credentials. “In this instance, the hackers set up fake websites that mimicked sign-in pages of Burisma subsidiaries, and have been blasting Burisma employees with emails meant to look like they are coming from inside the company.” Between similar methods, the fact that the former Vice President, Joe Biden’s, son was a board member for Burisma, and the upcoming 2020 election, Area 1’s CEO stated that he is “100%” sure who conducted the attack.
Area 1 is the cybersecurity firm that broke the news, so they are the firm that is cited in pretty much every article about this topic. Area 1’s CEO is Oren Falkowitz. He is the one that is quoted in the articles and is a former National Security Agency (NSA) employee. Since their report, according to Motherboard, “[…] cybersecurity companies FireEye and ThreatConnect have backed up Area 1’s claim about Russian involvement.” However, that article continues by stating both companies have, “[…] have hedged their conclusions about whether Burisma’s email server was breached.”
As mentioned earlier, virtually all stories covering this topic link the Burisma hacks to the 2016 DNC hacks, as well as the potential motive being to interfere with the 2020 election. This is in part due to who is allegedly behind the attack, the timing of the hack, the son of a Democratic nominee holding a high position in Burisma, and that Mr. Falkowitz stated as such. However, at the time of this writing, it is unclear what data was targeted and/or what was taken. Thusly, a political connection, at this time, is circumstantial.
