Great explanation man! Really appreciate your effort, which you put in your Videos and Streams!
New Patreon incoming.

[@_JohnHammond]

Super grateful, thank you so much!

[@damreyrizon9138]

Woah! I learned so much from you man! The way you explain things are clear and so articulate. Keep it up! Great work

[@_JohnHammond]

Thanks for the kind words, and thanks for watching! :D

[@alexmichmich4626]

i had a quick course about overflow, but your explanations are incredible ! Thanks

[@_JohnHammond]

Thanks for the kind words, and thanks for watching! :D

[@Kevin-vl3ow]

Fascinating challenge and explanation.

[@bugr33d0_hunter8]

Nice man. Never seen you do buffer overflows before. There tuff, I haven't gotten that far in my studies yet. But you explained it well. Seems like Ghidra is making reversing easier for everyone.

[@_JohnHammond]

GHIDRA is definitely awesome. I'll try to upload and showcase more reverse engineering and binary exploitation videos. Thanks for watching! :D

[@yashwanthkl4420]

That was a cool challenge!! Hope to see much more reverse engineering stuff!!!

[@KCM25NJL]

I mean, it's a really cool demo of how to essentially engineer these exploits...... and very well presented. My only question is how you would have tackled this (if possible) without the binary being so generous and providing the welcome address?

[@ahmedlimam2241]

I loved this so much! Thank you

[@_JohnHammond]

Happy to hear that! Thanks for watching!

[@vic2734]

Great video! I would like to see more reverse engineer stuff.

[@viv_2489]

This is perfect example of exploit development, holds all basic concepts

[@270jonp]

Pretty good video on this type of topic.

[@KaleshwarVhKaleshwarVh]

I didn't know these tools, I understood the flow though.

[@RohanOnBike]

This was nice as always, a small doubt why didn't u open it in edb and done it in the classic way, more people would have understood it... Maybe 😄

[@OnlyLevels]

Super cool explaining

[@_JohnHammond]

Thanks for watching! :D

[@Raj_darker]

[@elikelik3574]

Hi John, thanks a lot for the explanation. I really appreciate it. I'm a beginner that is why do not understand everything. What do You advise to me? How can I learn it very well?

[@_JohnHammond]

Thanks for the kind words! :D Have you jumped in the Discord server yet? I always recommend Bandit from OverTheWire to get your Linux skills down pat and then PicoCTF. Thanks for watching!

[@elikelik3574]

@@_JohnHammond Yes I'm already there, I mean in the Discord. If honestly, I did not know what is "Bandit from OverTheWire" but thanks to google got it =D Thnaks you too for the hint. I'll improve my linux skills. By the way, do you use Kali?

[@_JohnHammond]

@@elikelik3574 Awesome! I don't usually use Kali, no -- unless it's a real pen-testing oriented game I install most of my tools as needed.

[@elikelik3574]

@@_JohnHammond Cool. Then I continue with Kali because it is easiest way for me :D Thanks for the reply.Have a nice weekend.

[@yoavsarfaty8162]

What's the outro music?

[@ashutoshpanda4336]

Is the ctf is publicly available or do I need a team n something to try this out.... ???? If not you please just upload this file to discord chat ??? Please

[@chiko3603]

i want to consult u on something i found if thats possible

[@jacobwalters9660]

Wow using pwntools is a way useful skill. I like seeing making a script to exploit.

[@_JohnHammond]

Thanks so much, and thanks for watching! I need to put out a formal video series on working with pwntools ahaha.

Nada, zero, didn't get anything at all... F#CK!
