Reverse Engineering with Binary Ninja and gdb a key checking algorithm - TUMCTF 2016 Zwiebel part 1

[@MoritzDerErste]

Awesome video! I remember watching this one year ago shortly after release. It was pretty confusing for me back then because of lack of knowledge and understanding. Now, ~ 1yr later... it makes so much more sense to me :)

[@pasettodavide]

Super intresting!! Can't wait for part 2!

[@MarKac9090]

me too!

[@4ce5bf154]

I don't know how I ended up here and couldn't understand anything but already feel smarter

[@femerces]

Well done!

olha soh qm eu acho ake. Sem querer encher o saco, mas qual a calling convention q esta sendo usada nas funcoes que a main chama em 1:05? Parece System V AMD64 ABI, mas nao esta 100% igual, eu acho :/

[@AbacateSexy]

I'm, late to the party, but what calling convention are these functions at main @1:05 using? Looks like System V AMD64 ABI, but there are some inconsistencies :/

[@nahiyanalamgir7614]

I'm wondering the same. It indeed does look very familiar to System V AMD64 ABI.

[@musicislife561]

I didn't get this challenge during the competition. It was driving me crazy lol. Thanks for the video!! Btw what's your handle for ctfs??

[@LiveOverflow]

+Tyler Luke cool. I hope I made it clear for you now :) Next video will have the complete solution.

[@Borgimanio]

Me too, it was driving me nuts :D I circumvented the debug-protection and totally understood how it worked, but I had no idea, how to script this...

[@mufmuf]

I wonder how this challenge was created

[@ashikombat]

Thanks!

[@carljustinemosquida9614]

thanks for this!!!!

[@arunrmyt]

Cool and awesome skills. Can you help with a video on extracting zip file password using radare2?

[@brian-pf5dk]

nice vid and all that stuff, but please answer one question: "Why do you use a mac?"

[@geekgeek8453]

Excellent Video. what is Vagrant linux vm? is it another linux distro?.

[@LiveOverflow]

+geek geek I kinda used the wrong expression. Vagrant is basically a command line wrapper around headless virtual box. Meaning that VirtualBox executes any Linux Distribution and vagrant makes that super easy. You can have init scripts that setup the VM like you want etc. there is a vagrant CTF vm, which is just a bunch of vagrant config and setup files that start a ubuntu or Debian and install all the tools you need.

[@rj-nj3uk]

Is it okay to not understand anything?

[@meudta293]

many interisting videos in your channel but I am very behind can you propose what shold a study before whatching this ? I only know c++

[@silverzero9524]

Watch John Hammond KZbin videos. He has many easier CTF challenges

[@OptimusWhey]

I still live here.

[@neurocipher4474]

We all live here. We can never leave.
