FP adjustments 
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`

Expired happens too often 
Back then when we created this rule, we noticed that "logon attempt with expired account" happens pretty often, so we decided to not include it. All event codes in this rule did not appear in a 30 day time period and therefore the rule's "level" was set to "high".

Create win_susp_bcdedit 
This is a more general rule for possible boot/mbr value edits using bcdedit that I have seen in the wild.
It is different than 3288f6425b/rules/windows/malware/win_mal_wannacry.yml
because it is not specific to anyone family (of malware) and also has different CLI options
