When talking about executables, you should rather look for segments than sections. Sections are more for organizing the content of the file in some way. Segments, on the other hand, is what describes the executable image and how it should be mapped into the address space of a process in memory. Segments are described by program headers, not section headers. Sections are more useful during the linking process (either static or dynamic).
Wtf did I just read?
I agree with the "poking around" thing. Often times you wont actually understand what ur looking atat the time but having the familiarity with seeing the stuff will make it easier to learn later.
I should not have taken a sip before you said "Lil Endian"
@@tripplefives1402 I have an idea: let's ban SJWs. That could solve so many problems! :J
@Hatwox Lol wut? SJWs are paying you? How? And with what? Candy? :D
I meet these prerequisites, so I am excited for the series. Also, I like the art style. Communicates simplicity and welcomes learning
Going to share it on all the media I'm in.
This content is underrated
🙏
From now on, atleast 2 videos a month :)

Yeah....
Excited......
Once a week works for us too !!
Would be great if you increment it by two :)
Amazing dude, keep going - we like those
The neighbours dog started barking the exact moment you started talking about it. I thought I was having a seizure for a moment
your graphical presentation is top notch
i’m sure that your channel will grow a lot if you keep making them
4:55 - "if you hear the dogs barking..." - my neighbor's dog actually started barking
LMAO I was looking for this comment as the same thing happened to me
Your heads were compromised!
You have to go to sleep immediately so hacker couldn't read passwords from your memory!
;-)
Literally ... Is this binary exploitation
@@udaynarayanmukherjee5208 No, it's psionic exploitation :)
wtf my dogs started to barking
why tf is this channel soo underrated!? i watched the video and scrolled to see the subcount expecting a few million!
Maybe because it isn't really that great? :q
(Which might not be so obvious to a novice who cannot tell the wheat from the chaff yet, so everything new will sound "great" to him.)
@@bonbonpony i wouldnt expect professional grade content on UA-cam either :)
@@joshuabharathi706 Why not? That depends on who makes the video and how well does he know the subject. Have you seen LiveOverflow's videos, for example? Or programming videos by javidx9, Bisqwit, Jacob Sober etc.? Or electronics videos by Ben Eater? Or math videos by Michael Penn or Matthew Salomone?
There are people on UA-cam who teach good stuff too, and you can recognize them by the fact that they actually do what they teach, not just teaching about it, or "making videos as they learn" (the latter is rather an indication that one doesn't know yet what one is doing, so expect lots of misconceptions).
@@bonbonpony ok so make professional videos yourself then if this is so awful (it isnt though, this channel is amazing dont take it for granted man)
@@ithaca2076 I wish I had time for this, but at the moment I don't. Nevertheless, I don't have to be a master chef to tell if the soup is not great (which isn't the same thing as bad), so I don't quite get the intention of your comment. Are you suggesting that if I don't make videos myself, I can't criticize others even if I see their flaws? Then I could reply with the same argument towards you, because you don't make such videos yourself :q
I studied this last year and this gives me totally different angle look how this stuff works. Thanks for covering this topic
Thanks making these because as they say. "If you wanna catch a thief be a thief"
Youre truly underrated and you revolutionize the lives of your viewers. Keep up the work and keep up the awesome series
Hey i saw your website didnt know you also watch this
the simplest Explaination I've ever found as well as outstanding editing. Feeling really fortunate to be a your subscriber
This is actually pretty useful if you're planning to do manual mapping of executable image. Understanding the sections and what it does will help you in clearing your tracks. I used this as a reference to create my own manual map binary injector
Your videos are such great quality, I’m so glad I found this channel! Cheers from a Spaniard.
Great job man. What hardware/software do you use to make your illustrations. Looks amazing!
Thanks!
Hardware: A cheap Wacom drawing tablet.
Software: Adobe animate cc for drawing. Camtasia for recording, and Video editing in Adobe Premiere pro, Audacity/Auditions for audio.
Good one lil Endian!
Love it! Your channel is simple, clean, and well made!
So underrated, it should be around 1 Mil subs + by now
You nailed it. Just with this introductory video I GOT HOOKED and interested to learn and advance more in binary exploitation... Keep it like that. waiting to see and learn more together
Damn, I guess you can read my mind. First SSTI, then deserialization attacks and lately I'm interested in binary exploitation and now you upload a video about it! Great :D
Everyone's gangsta until the instruction pointer starts pointing at malicious code
Addicted to the sound when it starts 😹
Your intro is in one of my favourite list, it's a list of hundreds items, yet a list of items less than 10, as of now...
thanks god there's people like you and like liveoverflow
There were more then 10+ channels in the liveover flows vid but when I see the PwnFunction name! I was like this channel looks interesting by looking at its name and it is awesome channel, great vid btw!!!!
Going to need your terminal theme please :D
I really love your way of teaching
I really enjoyed this video. Thank you!
my pleasure
Haven‘t heard of bat before. Seems like a great addition to my tool collection! Always hated the missing syntax-highlighting with cat...
the tool is called batcat
Dude, this is top tier educational content, thanks for sharing!
We're going to talk about cars for now, maybe bicycles and Toyota in the future...
This is the best video i have seen about Introduction to Binary Exploitation.........Thanks : )
Thanks for the bat one! I didn't knew it, although I have to call it as "batcat", I'm running Mint and it seems like "bat" itself causes conflict on the distro, but who cares, really worth it for such amazing prints!
I love how 1337 this channel is from the name and avatar to the music :))
"it's important to overshoot while learning"
I'm going to bring this with me for the rest of my life
I'm really looking forward to more on this topic. your videos are amazingly awesome. definitely one of my favorites. up there with ippsec and liveoverflow ✌
Absolutely love this initiative! Great video brother!
I love the 0xa word
Great explanation and experimentation on binary exploitation PwnFunction! I actually didn't know about the readelf linux command! Thank you for sharing!
Last command was top notch
That's amazing man!
I'm so excited to watch em all!
This is perfect! I have a big test in two weeks over this exact topic!
Learned about your channel from liveoverflow's video and i gotta say this is damn good.
the most awaited series...please do post on regular basis ...
Dude .. the Dogs are barking in my head ... I am dying
2:08 ARM isn’t an operating system it’s an architecture
I think he knows, he just phrased it weird by not mention x86
Just found your channel! Liked and Subbed. :)
Man, your videos are awesome, thank you for your work
hey, looks like it'll be a cool and well made series, subscribed, waiting for more:)
The best ethical hacking content creator, explains complex things in a very basic way 👍
LiveOverflow: Am I a joke to you?
😂😂🤣
No excuse my bad English, i wanted to say that you explain very complex things in basic low level way that even beginners like me can understand :)
No worries, glad I could help :)
The drawings look soo goood
yo lil man
noice start hope you can do many videos about it
Yeeeeey I really love your videos
Nice and clear, thank you!
You'll definitely reach 1M subscribers very soon. I can feel it! Also +1sub from my side. Keep it up.
I don't think a like is enough to thank you for this, so... thank you :) you make really great content and I love it each time :)
Love your vids
great thanks for that! Very clear and articulate!
Yes, finaly PwnFunction going to super saiyan at pwn
I love this I’m new to programming and yea huge video nice animations I just like your style of explaining things in a simple way 👍🏻
That's pretty cool. Congratulations !
Did not know about the strings utility... neat!
Excited for this series. Keep it up
Nice Video Man! Atleast Learnt Something !!
I would be glad if you tell how you make videos & these cool animations, what softwares you use
most waited content from best tutor in youtube
I love the esthetics of your videos! :) What color pallet do you use?
Really good content! Keep on!
Great video man!
This series is going to be awesome!
4:05 so you're telling me that ELF files have essentially the same structure as eukaryotic mRNA?
Introns and exons 😁
He is making these things interesting to me thanks dude 💚
More! More! More!
DUDE WTF actual dogs were barking on my streets when he said that. I thought it was coming from the video.
U made me sub in 2 mins
Very cool video, it deserves more views
Is this series based on ELF only or you're going to include Exe/DLL ?
Windows executables are called PE btw
I think gcc actually does the linking as well. So I don't think what you generated was pure elf64. Elf64 contains segments of just that program and leaving the extern parts as extern for the linker to link. So I think you need to use -c option to get the elf64 and link it with ld later.
Thanks a lot bro keep sharing 😊
Great video as always 💕
I also loved your terminal font and source code highlighting in the terminal, wondering how to get them 🥺
Literally dogs barking around when he said about dogs barking... xD
YAS! PwnFunction is back!!
Btw, there is nothing special about those names such as ".text" or ".data", you can rename them to anything else. what's special tho is their permissions, like the execute bit on the .text section, and the fact that the elf entry point is always located inside the segment that contain that section
So if i was to look for a hidden key would you recommend analyzing more of the .text section more?
very nice let's say very good explaning thank you
Youre awesome dude , love you
aesthetics
Can't wait for the next part
GREAT bro I am with you
How tf can this guy have so few subs, he definetly deserves more
UA-cam supresses actual knowledge
"Right! its all in ur head! including dog barking sounds!"
Thats what i tell my neighbours when they file a complain against us
U deserve more subscribers ❤️
❤️Pwnfunction( ) = lovefunction ()

Lil' Endian is the best rap name possible.
great video!
Liveoverflow having very good videos in this topic
but it goes to fast and most of the things go above head too fast learning track
@@mr_ehmed I love the way he explain. Recently he talk about serenityos which was awesome and learn something new from it.
@@xormagic5190 indeed he had good content but way too advance and fast

i just realized... machine code is an interpreted language where the cpu is the interpreter
good vid
at 1:22 you wrote the letter 'p' in 'concepts' like the letter 'thorn' ie: 'þ'
