Very interesting! I could integrate this in my Armadillo Key Tool (https://github.com/mrexodia/akt)...
The previous attack (as far as I know) was on a weak implementation by Baboon (http://baboon.rce.free.fr/index.php?post/2010/09/04/Armadillo-mange-des-ours-en-slips) but I don't think a brute force approach was tested in public.
You can get the best target by making your own unpackme, or try Armadillo itself...
The latest public (and custom) v9.60 uses:
Code:
Short V3 Level 10:
