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.

f0c8c428bb added rules for renamed wscript, cscript and paexec. Added two directories to the existing sysmon_susp_prog_location_network_connection rule. These additions are all fin7 related. 2019-04-08 08:07:30 -04:00

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".
