mshta running script code

mshta.exe is the Windows host for HTML applications. Here it was started three times to run script code: inline VBScript, inline JavaScript that loads a remote scriptlet, and a local HTA file. The log also contains every other process started on the same machines, and 2,215 process starts from a clean Windows 10 client. Write a rule that finds the three mshta starts.

Hint 1

Look at how each of the three command lines passes the script to mshta. Which part do they share?

Hint 2

Processes started by mshta are part of the same chain; matching them does not count as a false positive.
