Locate vulnerable Gigabyte drivers used by RobbinHood ransomware to turn off security tools.
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.

The following query detects if a device contains the vulnerable drivers. These are often, but not always, implanted on the target by operators seeking to use this technique to turn off security software.
For a query that detects a later stage of this technique, see Detect security evasion related to the Robbinhood ransomware campaign.
