Cybercriminals linked to Russian military intelligence are allegedly part of the Strontium group.

Microsoft Corp said that its specialists managed to thwart attempts by Russian special services to hack multiple servers in Ukraine, EU countries and the United States.

A report published on the company’s official blog states that a group called Strontium used seven Internet domains as part of a hacking campaign aimed at government agencies and analytical organizations in the EU and the United States, as well as against Ukrainian companies, including a number of media outlets.

Microsoft has not identified any of the organizations that could potentially be attacked by hackers.

Strontium is also known as the Fancy Bear group or APT28, a group of hackers associated with Russian military intelligence.

The Russian Embassy in Washington did not respond to a request for comment.

Since the beginning of the Russian invasion, Ukraine has already been subjected to a number of cyber-attacks from a neighboring state.
