Slide 23 states that Garbage/Dead code is code "which runs but does not affect an intended result." Slide 23 further states, "An insertion of code which does not run is called junk code insertion." The first statement is inconsistent with the document, "Banescu, A Tutorial on Software Obfuscation, 2017," referenced on slide 15. Banescu states that dead code is "a branch that is never taken during runtime," and that "garbage code is always executed."

I recommend changing Slide 23 to be consistent with the definitions of Banescu. For example, remove "/Dead" from the slide title and replace "junk" with "dead" in the statement at the bottom of the slide.

Hi there,

reviewing the slides, I think the slide 133 has a typo. The second element should be "What are the deobfuscation techniques?", right?

EDIT: Please see comment below.

Going through the materials and found a problem in hands-on1 to run o-llvm.sh as no clang binary is found under /obfuscator/build/bin/ folder, where there is only llvm-lit

Environment:

• Fresh install of Ubuntu 18.04.3 on a VM
• Run ./setup.sh ./ as described in repository readme

Maybe some other dependency missing so setup.sh script not complete?
