A Russian group called Nobelium have been running a new campaign with ransomware designed to attack corporate and government systems. Nobelium was behind the SolarWinds attack.
Nobelium has been attempting to replicate the approach it has used in past attacks by targeting organizations integral to the global IT supply chain. This time, it is attacking a different part of the supply chain: resellers and other technology service providers that customize, deploy and manage cloud services and other technologies on behalf of their customers. We believe Nobelium ultimately hopes to piggyback on any direct access that resellers may have to their customers’ IT systems and more easily impersonate an organization’s trusted technology partner to gain access to their downstream customers. We began observing this latest campaign in May 2021 and have been notifying impacted partners and customers while also developing new technical assistance and guidance for the reseller community. Since May, we have notified more than 140 resellers and technology service providers that have been targeted by Nobelium. We continue to investigate, but to date we believe as many as 14 of these resellers and service providers have been compromised. Fortunately, we have discovered this campaign during its early stages, and we are sharing these developments to help cloud service resellers, technology providers, and their customers take timely steps to help ensure Nobelium is not more successful.
These attacks have been a part of a larger wave of Nobelium activities this summer. In fact, between July 1 and October 19 this year, we informed 609 customers that they had been attacked 22,868 times by Nobelium, with a success rate in the low single digits. By comparison, prior to July 1, 2021, we had notified customers about attacks from all nation-state actors 20,500 times over the past three years.
Use more secure passwords with 256-bits or more entropy to prevent spray gun attacks. Windows Defender can block the attacks but some companies are not taking enough steps to secure their own servers.
