Learning CTF: PicoCTF 2017 [08] Loooong (Python Strings)

[@fiegt]

I subscribed just now just because of the way you're explaining everything. The way it should be explained to a beginner! thank you

[@picklerick814]

trying hard not to watch like all videos in a row that you haven't released on youtube yet from your patreon.. as the challanges get more and more complex, when you really try to do them on your own and not cheat, it gets more and more addictive. because every challange is more effort, but in return leads to more reward when you did it. i totally see your point, starting slow with small challanges is the way to go. not just starting with really hard ctfs and then give up

A cool thing you can do (saw on gynvael's stream a while ago) is hold left alt and type the number of characters you want, then release alt and hit the character you want to be multiplied.

[@_JohnHammond]

WOAH. That is crazy cool; I had never known you could do that in the shell. Thanks for sharing!

[@CoderUnderscore]

Thanks lol, I was trying to input a python script into the shell thinking that it would automatically run and solve the problem and I was quite confused when it wasn't working. Keep up the videos they are useful for idiots like me ;)

[@joduaxddddd]

Great video!

[@_JohnHammond]

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

Blows my mind, watching recent vids, you still haven't picked up Vim over nano. Regex find/replace and being able to read CLI output into file ( :r !ls to read the output of ls into Vim for example) should be reason enough. It is damned strange at first learning to use it but the payoff is immense. As a hackish python user and newbie to CTF take it with a grain of salt but Vimtutor and a bit of googling is a gamechanger; even outside of CTF Vim is just magical for day to day linux usage. Anyway keep on being awesome and maybe do some super in depth RE stuff of you find the time. With no knowledge of C/C++ I always feel lost with RE challenges. If there are any tricks to it I'm sure I and others would love to know.

[@_JohnHammond]

Yeeeeeaahhhhh I do need to pick up Vim. I tend to really just use Sublime Text but now I'll try and switch over to vim. I'll try and keep some RE and PWN stuff on the way. Thanks for watching!

[@shiibudakgemink]

What happens if you don't rename the, um, folder name from "looong" to "looong_COMPLETE"? Also, I'm still confused when you put the "cd . .", what is the function of that? I know I'm totally late lol but I hope someone or you can answer me. Thank you for the videos!

[@mucktheman2720]

I use nano or emacs personally. I never really liked all the shorthand crap with vi or vim. I'm enjoying this series as it actually got me doing this CTF on my free time. It's been fun but it's making me wait to watch your videos until I've solved a challenge. lol I hope it doesn't take me too long to get to all of these videos.

[@_JohnHammond]

I dig nano. A good friend of mine showed me "micro" which is also super cool. Well sweet, I am happy to hear that! Thanks for watching. :)

[@yusufyilmaz5317]

How did you connected your terminal to the shell ?

[@cyb3rtooth199]

OMG he called me a leet hacker...

[@lucienalupei1472]

what no comments? :C

[@TryharderWoW]

Thanks for the great videos! :D This video got me excited to join in the fun and get on this CTF so I did. If someone's looking for an "automated" solution to this challenge I did it in python using the pwntools library. It's here on my GitHub: /Pedro-Bernardo/picoCTF/tree/master/loooong I'd really love to see it solved using a simple bash script or even just python using simple sockets, but after spending all day trying to do it I just gave up. If someone knows how to do it or can point me to a write up it would be much appreciated! ^^ I'll keep trying tho. Anyway, thanks again for your great content! Can't wait for the next videos.
