+# Detect loading of vulnerable drivers by Robbinhood ransomware campaign

+[Robbinhood](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Ransom:Win32/Robinhood.A&ThreatID=2147735370) is ransomware that has been involved in several high-profile incidents, including a 2019 [attack](https://www.nytimes.com/2019/05/22/us/baltimore-ransomware.html) 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 an early stage of this technique, when the operator is implanting the driver on the target.
+
+For a query that detects a later stage of this technique, see [Detect security evasion related to the Robbinhood ransomware campaign](robbinhood-driver.md).
+
+## Query
