As the one-year anniversary of the discovery of the SolarWinds supply chain compromise passes, Mandiant remains committed to tracking one of the toughest actors we have encountered. These suspected Russian actors practice top-notch operational security and advanced tradecraft. However, they are fallible, and we continue to uncover their activity and learn from their mistakes. Ultimately, they remain an adaptable and evolving threat that must be closely studied by defenders seeking to stay one step ahead.
Mandiant continues to track multiple clusters of suspected Russian intrusion activity that have targeted business and government entities around the globe. Based on our assessment of these activities, we have identified two distinct clusters of activity, UNC3004 and UNC2652. We associate both groups with UNC2452 also referred to as Nobelium by Microsoft.
