Hackers have already targeted at least three 2018 Congressional candidates, according to a Microsoft executive, who disclosed the attempted cyber-intrusions today during a panel at the Aspen Security Forum.

Tom Burt, corporate vice president for customer security and trust at Microsoft, noted at the panel today that the company had tracked attempts to use fake Microsoft domains for espionage activities in 2016. Those attempts were linked to a group Microsoft calls “Strontium” — the same hackers who targeted the Democratic National Committee in 2016, and who have been tied to Russian military intelligence. The company has been active in taking down those domains, he said, but similar activity has continued into this year.
