Reverse engineering enhances the understanding of both programming thought and skills. This video is easy to follow, and the main techniques of reverse engineering are shown clearly, which makes me want to decompile a small interesting program to analyze it.

read the book Code by Charles Petzold. You will understand how the CPU and assembler works even if you are a total noob. After that you will automatically understand how programming languages work, reverse engineering too and so on.

I prefer ollydbg 2.01 or x64dbg for 64 bit, ghidra makes really easy the reverse process, can get a source code... I prefer analyze asm instructions one by one for understand fully process but this isn't the best stategy.. one by one can take you a lot of time i use call stack window for locate specific part i want to analyze!

This was SUPER interesting and well made, please continue! You left us on a cliffhanger!

Wow that was probably one of the best descriptive reverse engineering videos I've seen to date. Your method of explaining and showcasing each step in each function is fantastic and even explaining how to identify when disassemblers/decompilers mess up and how to fix them. Bravo. I'm upset that I waited this long to actually start watching these videos.

Very interesting and complete video, first time I watch a reversing engineering video and I love the way you investigate and explain what you do. It's the first video of your channel I see and I love it. Keep going !

I didn't understand anything of what you did, but the casualness of explaining something so exoticly complicated drew me in.

Really well done video. I think you should keep this series in this format. Personally I like the pacing of the video, and wouldn't want it slower, or faster.

I came across your channel shortly after downloading Ghidra. I appreciate how you clearly detail your train of thought in each video. I hope to see more!

Fantastic Video, I hope to see more both on wannacry and other things soon. As an embedded SW guy looking to get into RE this was great.

You know too many things. You explain it too casually like it's food lmao. This guy be like: Ok, let me present you my house.

@@UCnPE-cqd00o5SHPn0rHxphg thanks for the support. I made a choice some years ago, leaving netsec to start studying at University a totally different thing: knowing today how this sector is growing, maybe my choice wasn't the right one. Today, with these excellent resources, is far more easy to fill the gap with skilled reversing ppl: some years ago they appear like a part of a niche, like an out of reach status. This effect is an outcome of how much the reversing job offers are growing (US government choice about Ghidra isn't random).

The thing that blew my mind the most, was the list of language translations you found in the passworded zip. Made me realize how much they really scaled this thing to take on the world. Absolute savage. Who ever did this was well organized. Do you ever wonder if they watched this video?

Awesome work as always. Keep it up

Very good video. Thanks for this video. That flowchart was helpful too. I have never seen reverse engineering in practice, this was very interesting. Very similar to debugging programs only here we don't have symbol information and have to create our own symbols, but it seems this Ghidhra tool makes things a lot convenient. Whoever wrote this malware must have very good knowledge of Windows API, maybe even about Windows kernel.

Amazing video, very good to follow and it helped me a lot with some frustrating 'features' in Ghidra. I found I was using the disassembler window more than the decompilation window because of weird decompilation results - you helped me understand getting better decompilation results by adjusting Ghidra's interpretation of some code. Thanks!

I have a few questions. I've done vb coding for years, but more as a supplement to my other work loads, I'm not a full blown dev. First, what was so hard about spotting the kill switch? There must have been a lot of the best devs looking at this code globally for 4 days, the guy who killed it even did that on accident. Secondly, and I'm not advocating for better viruses, but would a kill switch that the owner had exclusive controle over not be possible? They went to great lengths coding this but left the kill switch free for anyone to use.

This is fantastic, thank you

I hope to be as knowledgeable as you on this topic someday - please make a part 2!
