Fix CommandLine in rule sysmon/sysmon_susp_certutil_command
...
Below is an example of a test - the command line does not
include the path nor the .exe. I think this comes from the
initial detection on the Image path and the later switch to
command line.
We could also use both the Image path and the Command Line.
Message : Process Create:
Image: C:\Windows\SysWOW64\certutil.exe
CommandLine: certutil xx -decode xxx
Hashes: SHA1=8186D64DD28CD63CA883B1D3CE5F07AEABAD67C0
