Though Federal Civilian Executive Branch (FCEB) agencies are the primary targets, CISA encourages all organizations to up their security, given the high risk.

CISA has issued an emergency directive in response to Midnight Blizzard, or Cozy Bear, a Russian threat actor targeting Microsoft email accounts. The group is extracting information to access Microsoft customer systems. Strict security measures, including strong passwords and multi-factor authentication, are strongly recommended by CISA for all organizations (Microsoft included).
