      @trailofbits Can you share obfuscated calc.exe or some well-known malware sample to public? :)

      @d_olex @trailofbits Maybe! It would only demo the code diffusion, since you wouldn't be able to run one with environmental keying on.

      @dguido @trailofbits OK) Because, in my personal opinion, code diffusion can be de-obfuscated in a pretty trivial way.

      @4Dgifts @dguido @trailofbits Check the post in their blog. As I understanding - It's a way to break pure static CFG traversing.
