The US Department of Justice has announced charges against a Russian national for his alleged role in a series of disruptive cyberattacks against Ukraine ahead of Russia’s full-scale invasion in February 2022.

The individual, Amin Timovich Stigal, is believed to be a member of Cadet Blizzard, a state-sponsored threat actor also known as DEV-0586 and Ruinous Ursa, which operates on behalf of Russia’s military intelligence (the Main Intelligence Directorate of the General Staff (GRU) of Russia).

Not sure if that's what you're referring to.
