This query was originally published in the threat analytics report, Solorigate supply chain attack. Please note that these attacks are currently known as the Nobelium campaign.
Microsoft detects the 2020 SolarWinds supply chain attack implant and its other components as part of a campaign by the Nobelium activity group. Nobelium is the threat actor behind the attack against SolarWinds, which was previously referred to as Solorigate.
Nobelium silently added malicious code to legitimate software updates for Orion, which is IT monitoring software provided by SolarWinds. In this way, malicious dynamic link libraries (DLLs) were distributed to SolarWinds customers.
The following query locates malicious Nobelium-associated DLLs that have been loaded into memory on affected systems.
More Nobelium-related queries can be found listed under the See also section of this document.

This query was originally published in the threat analytics report, Ransomware continues to hit healthcare, critical services. There is also a related blog.
Robbinhood is ransomware that has been involved in several high-profile incidents, including a 2019 attack on the city of Baltimore, Maryland. Robbinhood operators often employ a distinctive defense evasion technique, where they load a vulnerable driver on to a target and exploit it, in order to turn off security software -- essentially using the driver as malware.
The following query detects a late stage of this technique, when the operator is issuing commands to turn off the driver.
For a query that detects an earlier stage of this technique, see Detect loading of vulnerable drivers by Robbinhood ransomware campaign.
