After @thomaspatzke changed to HKU, I did some reading. HKU is for HKEY_User, not HKEY_Current_User (what this threat is tied to. However, he was correct that HKCU does not exist as a prefix for sysmon (see the notes section under event id 13 here: https://github.com/SwiftOnSecurity/sysmon-config/blob/master/sysmonconfig-export.xml). Changed to ignore the key name, confirmed that the key is still uniique.
