The corresponding statement was published on the website of the National Security Agency.

It states that the program for the Linux operating system is being implemented by "unit 26165 of the 85th Main Center for Special Services of the Main Directorate of the General Staff of Russia", which in the private sector is called "Fancy Bear, Strontium or APT".

As noted, "Woodcutter" provides the ability to upload and download files from the computer of a potential victim, receive information about online activity, as well as set various tasks and mask hacker activity.

"The woodcutter is a threat to national security users, the Department of Defense and major defense industry customers who use Linux," the statement said.

The American intelligence services did not provide any evidence.

In the fall of 2018, the American edition of The Daily Beast wrote about new malicious software, which was developed by the "Russian GRU" and the hacker group Fancy Bear.

Russia has repeatedly denied US cyber espionage allegations.
