ACTINIUM targets Ukrainian organizations

Since October 2021, ACTINIUM has targeted or compromised accounts at organizations critical to emergency response and ensuring the security of Ukrainian territory, as well as organizations that would be involved in coordinating the distribution of international and humanitarian aid to Ukraine in a crisis.
As with any observed nation-state actor activity, Microsoft directly notifies customers of online services that have been targeted or compromised, providing them with the information they need to secure their accounts.
Microsoft has shared this information with Ukrainian authorities.

ACTINIUM represents a unique set of activities separate from the destructive malware attacks by DEV-0586 described in an earlier blog post.
As of this writing, MSTIC has not found any indicators correlating these two actors or their operations.
The observed ACTINIUM activities detailed in this blog have been limited only to organizations within Ukraine.
Microsoft have not seen this actor using any unpatched vulnerabilities in Microsoft products or services.
