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
