      This tool can be used to detect any app compiled with dotnet framework during runtime even if it was packed.

      As said in the vid , Most of the packers/obfuscators just adds your PE to their stub and executes in memoy . It's pretty easy to unpack most of them if you know what you are doing.

    2. I can't think of a point posting this here but well this might help people like sergemorel and dethblaze hiding sensitive data from NM. Also for people who is planing to code a login system

       

       

      The only way i might think of people getting the right hwid is bruteforce otherwise only patching , the rest is on you saving your a--

      As i said in the vid , you can add a database or whatever i just made it for the tut,

      Some skids use some packers which mods some bytes of the header to make it unreadable , that's why .net reflctor can't decompile it.

      Decided to code this simple application which fixes it for you.

      Only packed to decrease size if you want the sourcecode anyone you can pm me

      But it is really easy to guess the code as most of modded headers just change the byte at the offset 0xF3

      I finally managed to do it after many attempts , it's just about writing bytes around the file offset . but gl getting the offset.

      Was going to use this for my obfuscator but since I stopped working on it i decided to release this

      I can't give to my self much credits to this as most of the credits go to:
