EXAMPLE 01T1218

Once executed, `change.exe` will execute `chgusr.exe` in the same folder. Thus, if `change.exe` is copied to a folder and an arbitrary executable is renamed to `chgusr.exe`, `change.exe` will spawn it. Instead of `user`, it is also possible to use `port` or `logon` as command-line option.

COMMAND

change.exe user

USE CASE: Execute an arbitrary executable via trusted system executable.
