A familiar cyberattack suspect linked with the Russian intelligence service has resurfaced in the months leading up to the U.S. midterm elections, according to Microsoft. The tech giant announced overnight that last week it executed a court order to disrupt six fraudulent websites set up by a hacker group known by many names — most often APT28, but also Fancy Bear or Strontium, among others.

The unit has been associated with the Russian spy agency GRU and blamed for a raft of high-profile hacks across the world in recent years — including the breaches of the Democratic National Committee’s network during the 2016 presidential election.
