Hi all. Here is a Armadillo 9.64 (X86) unpackme made with a custom build. The file is bundled with (almost) all protections that Armadillo can provide. There are many tutorials regarding Armadillo unpacking so i guess is not a great deal to unpack even it haves many layers of protection that Arma can provide. If you look deep in the unpackme you will find the weaknesses. Good luck! Goal is unpack and make a tutorial for others to see and learn because all it remains is the lagacy of tutorials witch are passed from one generation to another. Unpackme.7z
