Add new rule for detecting MMC spawning a shell 
Add (analog to win_mshta_spawn_shell.yml) a dedicated rule for dedecting MMC spawning a shell. See https://github.com/Neo23x0/sigma/blob/master/rules/windows/process_creation/win_mshta_spawn_shell.yml. And it should cover the (removed) cmd part from the existing rule https://github.com/Neo23x0/sigma/blob/master/rules/windows/process_creation/win_susp_mmc_source.yml.

We have checked the False Positive rate in different environments and noticed these event IDs in cases in which systems had bad network connections / we accessed via VPN. Therefore we reduced the level to "high" and added that note to the "False Positives" list.

Update win_mal_ursnif.yml 
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.

Create win_etw_trace_evasion.yml 
there are two versions of clear and two variations of set that can be used with something like wevtutil
`wevtutil cl | wevtutil clear-log | wevtutil sl | wevtutil set-log `

Also, I am adding a `*` match at the end, because there are other parameters that could be placed on the end -- so unless this was used on a general search on a text/analyzed field then the `*` is necessary.

example `wevtutil set-log Microsoft-Windows-WMI-Activity/Trace /e:disable /q:true`
