Resources To Learn About Crypters
« on: September 24, 2015, 02:57:24 am »
I have been learning C++ for a while now and encryption interests me a lot, so I thought I would start learning about it. That then go me onto looking into crypters, I liked the idea and wanted to learn more about them and maybe code my own one day in C++, but I knew I was far away and needed to start somewhere. I did, I Googled around and learnt as much as I could, however most links were about websites trying to sell already made crypters. I did gather some decent links and websites that had good information about crypters on; I have been on the forum and seen:

https://evilzone.org/programming-newbies/(c-source)-cli-stub-crypter-(noobfriendly)/msg106155/#msg106155

https://evilzone.org/c-c/(c)-simple-crypter-stub/

Which I intend to look at when I have time. However, my question is do you guys have any websites with information about crypters? - How they work, detailed information about binders, packers EOF and such... I just thought it might be worth asking some people with experience in this field and if you know any websites which provide information about crypters where I can learn from. 
Its nice to be important but always important to be nice!

Your best bet is probably to look and/or Reverse through other open source cryptors. Found this one on github:
https://github.com/jozemberi/PE-Crypter

Then I also found this on some random hack forum that's not hackforums lol, be careful I didn't check any of the files

The one damn source i trust that has concise information about this, well explained and heavily researched is by our own Deque. For some reason she scraped it off the internet so i would recommend you reach out to her for your own private copy, if she feels like it.

While you are at it, read through this paper by nullsecurity, should help you out: https://github.com/nullsecuritynet/papers/raw/master/nullsec-pe-crypter/nullsec-pe-crypter.pdf
And this paper discussing ideas of advanced runtime encryption of .NET executables: https://github.com/nullsecuritynet/papers/raw/master/nullsec-net-crypter/nullsec-net-crypter.pdf

God speed while you learn.

If you can't explain it to a 6 year old, you don't understand it yourself.
