I've always struggled understanding registers, but as someone with an uncle that's on the same register as yours, I now fully understand them, thanks! #FreeAllUncles
I always wondered how people made cracks and stuff, now that I've learnt some computer science and watched this video, I didn't realise it could be so simple.
@@GamerFigureyes but I think they’re just surprised how easy it is to wrap your head around this stuff. Every system seems so complex until you break it down, step by step and practice until it becomes trivial. Those who don’t practice will never get better and can’t gain the necessary wisdom that comes with time.
See this is the kind of content people need to watch when researching complex topics like this. Literally just needed a small bit of Info from this video and got it In seconds good job!
I've been into reverse engineering since way back in 1998, so I have some experience in this area. I just wanted to say that your video is pretty good, and I appreciate your honesty about your skillset. I have a few suggestions, though. It would have been helpful if you explained the JMP (jump) and why you made changes to that particular code. Additionally, it would have been better if you mentioned the option of using NOP (no operation) as an alternative. In this case, if you NOP the code at 4012BC, it would automatically move on to the next line. Ultimately, you achieved the same outcome by making it jump to 4012BE, but it's worth noting that you could have just NOPed the jump, especially since the "Good Boy" comes first in the code. It would have been beneficial if you also explained what JNE means and what the comparison was. Another suggestion I have is to use a breakpoint at 4012AB, then proceed to the next line and examine the stack. If you did that, you would see your correct serial number pushed onto the stack. Anyway, your tutorial was very easy to follow, especially for beginners. Great job!
if I had a program with different .exe, because each of them are a piece of the whole program 60GB, How do I know which one to crack? programs name is Siemens Tia V17
@chrishultberg4223 Hi, I want to become a reverse engineer by self-studying. Can you please recommend videos that are beginners-friendly to follow? This one was understandable, but like someone in here said, that programs these days are not that simple.
@@liloufdezlaralopez8334 In order to figure that out, you would just follow the code, line-by-line until you end up in the code that needs modification. When debugging applications, they will load the required resources or additional ".exe" files as needed and ultimately, you should end up on a line or routine that you would need to modify in order to meet your needs. Sometimes it's a ".dll" file that the executable has loaded and you would modify that file the same as you would a ".exe". I hope this helps.
@@Ewin501 Do a search for "crack-me" tutorials and videos. These applications are designed specifically to practice on and are a great place to start. If you do not know how to code, it would be wise to educate yourself in the basics of programming before you dive into reverse engineering.
Another simple solution is just changing the opcode relative address to 00 instead of 16 so it becomes "75 00". As 75 is the i386 opcode for JNE("Jump if not equal") instruction it will just jump to the line after the instruction. A different way to think about it is like the following. if(key != correct) { correctKey(); } else { correctKey(); } Both paths lead to the same function in memory.
I’m currently working towards an It degree, and I’m almost done. I straight up learned more from your quick video than I have in any of my classes. Awesome vid man!
Another important thing to mention is that not every registry key system works like this. 99.99% of modern implementations call back to a server that can validate if the key exists, and it's randomly generated per user meaning the only way to crack it is to either remove the key check from the client, or to get the server to generate a key for free.
can people crack modern games by removing the key check from the client, or to getting the server to generate a key for free? is it possible to do either one of these two things at all?
@@Santificated Some games are vulnerable to being cracked and able to go online, but for most games any offline play can be made available just by skipping the online check, yeah.
Clearly you pulled that 99.99% figure out of a certain orifice. Many developers are opposed to their applications having any sort of call home function, not just for privacy reasons, but also because it places limitations on how and where users can use the software. You can also use public/private key encryption to verify a key is legitimate, without calling home. Personally, I don't really mind if people choose not to pay for my software and just use a cracked version. Props to those who crack it themselves.
@@bobbuilder3748 using offline public/private key encryption to verify a key is vulnerable to reverse engineering, and so any application one might seriously want to crack that the creators seriously don't want cracked will use call home DRM as OP describes. Not sure how either of you are getting your data, though.
@@sly-shot Correct. Public/private keys will not prevent reverse engineering. It's still possible to bypass the key checks, but it prevents key generators from being distributed that will work against unmodified releases. I'm not supplying hard data, just observations from my 20+ years working in the industry. I live in a country with strict privacy laws (although about 8 years was working for multi-national companies), so perhaps it's different elsewhere, but any time a call home feature is suggested, there has always push back from developers.
The tools are way better some 24 years later! I used to do this with a hex editor for fun... Because the games usually aren't as fun! The shock of seeing what they did to create a more difficult keying code was fun. Some were NASTY the more money you had to sink into what it was back then... I'm trying to fix old GTA 2 to stop checking for the darn disc and spinning it like crazy! My vintage PC rig is vintage enough that I don't want to see it lose the DVD drive... Unreal 4 at 560 fps on older hardware is to crazy!
so this is how normal ppl start learning reverse engineering. I just jumped straight into the difficult stuff, didn't get anything since the program was rather complex and used multiple system libraries and i just dropped the shit even knowing a little more about computers than this vid explains
I did this exact "exercise", although with no UI in Linux and a really primitive debugger, in my Assembly Language course in my fifth semester. I remember looking for the password for five days while searching through thousands of registers and trying different subroutins until I realized that I could just change JNE to JMP and be done with it 😂.
In the crackme community you are expected not to simply change the binary file (also called patching), but to write an external program that provides you with valid keys. Only then have you really solved the task. The reason is simply because patching is far too easy.
i have nitifications on but i never got notifs for the last 2 videos lmao -- only reason I checked the channel again was cuz of some bot in ur comments .. but I remember this being a good video so .. good reupload :D
Thank you so much for sharing your amazing video with us! Plz consider start a playlist solving all the challenges in the website you mentions, like once a week. Thanks in advance!
so you basically convert a program into assembly code, find an error message that gets sent when you put in the wrong code, look for that in the assembly code using memory spots instead of variables/strings, then attempt to understand how jump if not equal statements work, and then find the conditionals for that statement. and that's how you hack into ubisoft :)
this video is explaining something that look very f#cking overwhelming and yet it does in a hillarious way and it do teach how to no get intimidated by assembly, good job dude
I mean...that's not what they mean when they say write a keygen. The whole point is to reverse engineer the algorithm to find out how the password is created for the given username. While this is technically a "key generator", you're still just patching the program.
this video led me to take the computer architecture course at my school. thank you for opening my eyes man. i might have graduated with cs without ever touching assembly
Cool. I remember downloading cracks and keygens back in the day. There was always that moment of hesitation. Do I want to keep using this software or do I risk getting a virus? The best keygens were the ones with that kickass midi music.
Just downloaded x64dbg and gave all this a shot, it was piss easy! Just going off memory (no pun intended) and clicking through the video a couple times I got it done in less than 30 minutes, and the second time I did it, while screenshotting each step to my mate, took me around 6 minutes. Super educational video!
Great video! Super clear and entertaining :) Question tho... What if you can't find the string with the dialogue from the registration box? I've tried searching for every bit of text in there, but I can't find anything as cut and dried as the "bad boy..." example. How do I find the right code if I can't search something that specific?
Same issue with a program called "My Recover". Presumably not a rare issue to encounter. So it would be surely worth to address instead of leaving it unanswered.
I used to be mind blown that people could make this type of stuff. and i wouldn't have known where to start even now, but i've been working on my bachelors in compsci and just took computer architecture & assembly language maybe 2 quarters ago and could actually understand the assembly stuff which felt pretty cool!
I think of it as basic instead of outdated. Cracking programs with modern means of defence would probably be too hard and boring for the target audience
NK. Hahhaha. One of my targets, NK. XD 💀😅😂 Great video, bro bro! Entertaining, indeed. Hehe. I found you in my feed, liked, subbed, and shared. Fellow ethical hacker.
Yeah that was pretty straight forward, as long as you're able to read assembly. That explains why almost every login or password system I've ever came across uses servers.
Great video, though a bit over my head. I came here because I want to debug/decompile a databin unpacker--the one tool that's out there seemingly doesn't extract everything and I have no idea the compression method used to try and get into it myself. I have my own tutorials on hex editing save files and messing around with a game's active memory to make instant changes, but this would be a leap for me. If you check your comments, would you be willing to give me some direction? Thanks.
If the key on this crackme is always the same then it is not that much of a challenge. A crackme in which you HAVE to understand the algorithm that generates a different key for each user and you have to do it without bytepatching would be way harder than this. Even then, compared to the amount of obfuscation, anti debug measures that software has nowadays, makes cracking a bitch to deal with.
Exactly, you will have to regenerate (Pseudo) Code for the algorithm that takes String as an input and generates an Int by passing it through the function call of the algorithm.
I like to make these more challenging- You could make it autofill the password field with the correct code, or even just bypass the entire login on start up.

Hello, can I ask you something, maybe you will find it interesting. A ransomware called x101 encrypted my . 500 gb in one minute. The files now have the extension .x101 . After researching the vrus seems very new, it's about half a year old and from what I've read about OTHER ransomware I think my files were partially encrypted, just the beginning and maybe the end. The files are TS video files from 700mb - 4GB each. Fortunately, I had saved some files on an external SSD. It appears that the encrypted files are exactly the same size as the original unencrypted files on the external SSD. I already tried to snap the extension back in place, it didn't work :)))) why did I think it would work? Is there any possibility to find the encryption mode by comparing an infected file with the uninfected one (identical file) or to delete the encrypted part and leave the code unencrypted and the video will go, possibly missing the beginning and the end? With what program could I open them to see the binary code consisting of 0 and 1? Which is better according to you, free and open source if possible. I know there is always a pensource / free variant.
Love that in 2023 youtube hacking videos are like this. Many years ago I was attempting this for my first time, if I had your video it would have been so much easier.
didn't even know that this was known as reverse software engineering. we did a lot of this back in the day when we wanted something (like flashfxp for xbox modding). me and my buddy used hexeditor and learned by fkn around and screwing everything up. just had to identify where to do changes. was way easier back in the day though.
I used to do cracking and keygening in my high school and university time too (learn mostly from Lena’s tuts. Miss her.. 😢). Now I don’t have time and energy to do that anymore. So instead I watch people do it for the nostagic feeling. You may do the same later at my age 😂

After researching the vrus seems very new, it's about half a year old and from what I've read about OTHER ransomware I think my files were partially encrypted, just the beginning and maybe the end.
The files are TS video files from 700mb - 4GB each.
Fortunately, I had saved some files on an external SSD. It appears that the encrypted files are exactly the same size as the original unencrypted files on the external SSD. I already tried to snap the extension back in place, it didn't work :)))) why did I think it would work?
Is there any possibility to find the encryption mode by comparing an infected file with the uninfected one (identical file) or to delete the encrypted part and leave the code unencrypted and the video will go, possibly missing the beginning and the end?
With what program could I open them to see the binary code consisting of 0 and 1? Which is better according to you, free and open source if possible. I know there is always a pensource / free variant.
it could work if you know what exactly changed when you compare the 2 files
solid intro to reversing
Cool, always learn from you. Impressive
nice vid man
Rich Brian do be teaching us Reverse Engineering fr
Now I can't wait to see why DENUVO is so hard to crack.
Exactly, and it's worse when the only person able to crack it is crazy and former a cult.
Love that in 2023 youtube hacking videos are like this.
Many years ago I was attempting this for my first time, if I had your video it would have been so much easier.
Ayy its back, f youtube
didn't even know that this was known as reverse software engineering. we did a lot of this back in the day when we wanted something (like flashfxp for xbox modding). me and my buddy used hexeditor and learned by fkn around and screwing everything up. just had to identify where to do changes. was way easier back in the day though.
how with online activation programs...??
Free Kenny bro he ain't do nun wrong 🕊🕊
can we crack idm with this??
yeah :)
I used to do cracking and keygening in my high school and university time too (learn mostly from Lena’s tuts. Miss her.. 😢). Now I don’t have time and energy to do that anymore. So instead I watch people do it for the nostagic feeling. You may do the same later at my age 😂
When did you start this at what age?
3:30 song? xd

love your dynamic approach to creating engaging content!
Is this applicable to software license managers where they provide you with a request key, and then you need to get a activation key from their webpage? Or how do you crack those softwares?
This.
I think that is a crime
