Russian hacker group Cold River tried to gain access to 3 US nuclear laboratories in the summer of 2022

Russians created fake login pages to the websites of Brookhaven, Argonne and Lawrence National Laboratories.

They then sent these links to nuclear physicists working at the laboratories. The Russians hoped that the scientists would not notice the fake nature of the sites and compromise their passwords. 

Probably, the center of this group is located in Syktyvkar.
