NOBELIUM targeting delegated administrative privileges to facilitate broader attacks - Microsoft Sec...

The Microsoft Threat Intelligence Center (MSTIC) has detected nation-state activity associated with the threat actor tracked as NOBELIUM, attempting to gain access to downstream customers of multiple cloud service providers (CSP), managed service providers (MSP), and other IT services organizations (referred to as “service providers” for the rest of this blog) that have been granted administrative or privileged access by other organizations. The targeted activity has been observed against organizations based in the United States and across Europe since May 2021. MSTIC assesses that NOBELIUM has launched a campaign against these organizations to exploit existing technical trust relationships between the provider organizations and the governments, think tanks, and other companies they serve. NOBELIUM is the same actor behind the SolarWinds compromise in 2020, and this latest activity shares the hallmarks of the actor’s compromise-one-to-compromise-many approach. Microsoft has notified known victims of these activities through our nation-state notification process and worked with them and other industry partners to expand our investigation, resulting in new insights and disruption of the threat actor throughout stages of this campaign.
