328762ed67 Update powershell_xor_commandline.yml
Ducplicate names again for https://github.com/Neo23x0/sigma/search?q=Suspicious+Encoded+PowerShell+Command+Line&unscoped_q=Suspicious+Encoded+PowerShell+Command+Line . This brakes elastalert integration since each rule needs to have its own unique name.

Missing Character
Parsed the MITRE ATT&CK informations from the rules. My script crashed because the identifier "T" was missing.
Thanks for your work Flo & Tom!

Changes
I think that this is what you've wanted, right? If both keywords appear in a single log entry, right? 
Don't you think that this still causes false positives? Could "set-content" and "stream" be more common than expected?
