This is by far my favourite hacking related KZread channel, the story + CTF format works great as far as I'm concerned.

I think if you keep the story + film in the first part and the challenge in the second part (or vice versa), a lot of people would like it.

Agreed. The storytelling was interesting, but it made the flow of the video a bit unnatural. Try it the way suggested above.

Very impressive man. Really enjoyed your video and was satisfied with the story telling.

I liked the story telling and thought it added to the video and made it more interesting and entertaining to watch.

Very dope video walking through the various skillsets required to solve such a problem, as well as the need to understand the scope of a problem. De-obfuscation is really the secret sauce, once you understand the recipe manipulating it is just a matter of how lazily/efficiently you can execute.

I thought the video was a nice intro to why and where you made this. I like your humility. I also like the pacing of the video. Sure I wish you would slow down, but I can watch it again. You get to the solution quickly showing how each step fits together. I will rewatch closer.

I really like your videos! Great for learning how to deconstruct ctf challenges :)

As you asked if storytelling + reversing is good, i dont think so, because it breaks the thought process when you try to follow whats going on, especially for less experienced like me i think

same opinion here. Even though you'd just mentioned it the jump from the anti debugger to the story made me stop the video and say "wait, what?". I don't mind a story _and_ a debugging session/explanation in the same video but interleaving the two when the story isn't some part of the explanation (eg. a friend of mine pointed out...it reminded me of...) apparently breaks my mind :D

I agree. But, I like to hear both types of things, perhaps intertwined more thoroughly so it doesn't seem so jarring.

Love your videos. I'm learning alot from them.

Look at that Cake!!! Nice vid as always !!

Appreciate the honesty on how long it takes to solve ctfs

great meeting you dude! too bad we didnt get a chance to talk over a beer.

I'm going trough your CTF playlist and I find my country! Yaay!

I love it when you drop F bombs. Great videos. I'm sad that KZread algorithms took so long to suggest your videos to me.

Hey, do you know something about a IATool to reverse bins? IA used to auto reverse? Or IA used as a hacker tool in anyway?

Muito interessante seus vídeos sobre hacker, obrigado por compartilhar seus ensinamentos e por sua humildade em ser quem você é!

It sucked That the video ended 😭

why can't I register for this CTF? is it closed? when I press enter in the register form, the pages refreshes and nothing happened

i need to rewatch these, since first time i saw it i didn't knew shit about this stuff

I thought it was a good mix between talking about the conference and playing the CTF.

Wow great video

Nice video, have you got a link or a backup of the challenge files? The link in the video doesn’t work anymore

Hi. Where I may to find the pdf presentation (3:47)?

I'm asking for a favor pls make a playlist of all web app security videos from your channel. I'm a newbie to web app sec it would be really helpful for all of us. Thanks.

Hey, do you have a link for the CTF or is it down ?

Are you going to be at defcamp CTF?

Hahaha flag hoarding! Well when you're the main person who makes CTF videos, I guess people expect you to be a god!

More fun @liverOverFlow

i wish i could do this but where to start?

You can read "Hacking: The art of exploitation" and "Attacking network protocols". Also you can see LiveOverflow's binary hacking and web hacking playlist. I recommend you start with "Hacking: The art of exploitation" and the binary playlist first, then go for web and network protocol stuff. Also be sure to check out this invaluable reddit post: www.reddit.com/r/hacking/comments/a3oicn/how_to_start_hacking_the_ultimate_two_path_guide/

Interesting. I modify your code and use BitVec only, (I removed BV2Int) and the code produces unsat. However, in BitVecRef, there is __mul__ and __div__, so I think there is no need to convert it to Int (by using BV2Int) at line 61, 62. Then I figure out, that in line 61, the divide operation in BitVec is un-natural, so we have to use BV2Int. (pictures included) imgur.com/LUKQFnL TIL: __mul__ in z3 is great, __div__ is not.

Somebody added a portuguese translation to your video and the title simply sucked ass, I had to switch to english to understand what was happening...

I don't really like this style of mixing the write-up and the story-telling parts. It ruins both. Having both exist separately (either in the same video or as 2 separate videos) would be better.
