What it detects

This rule detects creation of a service loading the vulnerable Avast aswarpot.sys driver under the name aswSP_ArPot2. Cuba ransomware operators bring the signed driver into C:\windows\temp and register it as a service to abuse it via DeviceIoControl for terminating security products, a bring-your-own-vulnerable-driver technique.
