According to Microsoft, Cadet Blizzard has been active since around 2020 and targets various organizations in Europe and Latin America. Most recently, it has targeted Ukraine and NATO members that provide military support to Ukraine. After June 2022, the activity has not been confirmed, but it has been active again since the beginning of 2023.

Russia's threat actors are known as 'Seashell Blizzard' and 'Forest Blizzard'. All threat actors, including Cadet Blizzard, are associated with the Russian General Staff Intelligence Directorate (GRU), although Cadet Blizzard appears to be in a slightly different position.

Regarding Cadet Blizzard, Microsoft wrote, ``The emergence of actors who have carried out destructive cyber attacks in Ukraine that are likely to support broader military objectives is a notable development in Russian cybercrime.''

However, Cadet Blizzard also features a relatively low success rate compared to other threat actors. Seashell Blizzard's wiper attack in February 2022 affected more than 200 systems in 15 organizations, while Cadet Blizzard's Whispergate wiper attack destroyed enemy networks. Despite being trained, the range of influence was extremely narrow and the impact was small.

Although the attack success rate remains low after the resumption of activity in early 2023, some attacks are successful, and Microsoft is sharing information with customers to increase visibility and strengthen protection against attacks. .
