Cozy Bear
Cozy Bear, classified as advanced persistent threat APT29, is a Russian hacker group believed to be associated with Russian intelligence. The Dutch AIVD deduced from security camera footage that it is led by the Russian Foreign Intelligence Service (SVR). Cybersecurity firm CrowdStrike also previously suggested that it may be associated with either the Russian Federal Security Service (FSB) or SVR. The group was given other nicknames by other cybersecurity firms, including Office Monkeys, CozyCar, The Dukes (by Volexity), and CozyDuke (by F-Secure).
