I submitted the Malware Report for the WiCyS Cyber Defense Challenge. This has been a good introduction to malware analysis and tools (REMnux, exiftool, yara, cyberchef and OLE file analysis --  oledump, oleid, oletimes, olevba)

It took a long time for me to setup REMnux. Based on the hints, the next step should be to analyze the memory dump -- that is, maybe after I resolve the errors I encounter with Speakeasy and Volatility.  :)
