Affidavit in Support of Application for Criminal Complaint 0 A Russia-aligned threat group named Void Blizzard conducted a large-scale cyber espionage campaign targeting multiple U.S. companies between June and July 2024. The campaign involved harvesting mass emails and unauthorized access to Office 365 environments using stolen session tokens, proxy services, and VPNs.
