I read your comment before watching that part and I totally got the wrong idea lol Thought you meant that no-code "hackers" should not be looked down upon. To which I disagree. But by "tool" you were referring to the choice of language, to which I agree, hacking is a mess either way, the choice of language should not matter as long as it does the job.

I just assumed it's a running joke within the LLL community (especially since he's known for being a C shill, for obvious reasons)

Looks like a lot of fun once you understand what's going on and know ways you could tackle the proble

I've never commented on a video before, but I had to for this one. It's that good!

bro I could watch this every day that was awesome

Great video! Very informative and well explained.

Thank you, LLL, the font size saved me :)

How is it only now I find this gem of a channel? Dang youtube

Nicely done, Mr LLL.

I got into it back in the day because I bought a amiga game, it didn't run and the shop refused to refund. Got in touch with the local computer hobbies group, they knew about the problem with the game but still took the time to introduced me to 68k debugging and disassembly. Got the game running. Group introduced me to sas/c compiler. The rest is history. Also did step through every software I had to be fascinated and also to understand how it worked. 68k simpler times ... It is a valuable skill to have.

I love your merch, I have the mousepad and the t-shirt, do you have any other plans for more reverse engineering or low level related merch? I would totally buy more

Awesome work !

Thanks for zooming in!

I love this channel.

I have some experience with coding. The further this went on my head started spinning though. This is on another level, quite interesting ^^

Hey , very nice intro to angr, i have a bit that i didn’t get is why the first try with the 32.8 bit key space reached in the simulator the last address ? That for me doesn’t yet click

Terminal looks neat, what are you using?

Ngl I am pretty new to low level stuff but I recommend running it a bit first before even running strings

Do you have any recommendations on books that are useful desk references for this stuff?

Cool, next do Denuvo. Let's see how good you are!

So *why* does angr have issues with stdin and how were you able to work out the fix?

@Eugensson

3 ай бұрын

Why - just speculating here, because cpp streams are weird. How - he has emulated the result of the text input himself, he put the string pointer on the stack (this is exactly what that cpp function does after fetching the text), and he has skipped the stdin function.

Great video, I'm new to this stuff. couple of doubts, when giving the address of the good and avoid case, why is only 4byte address is provided instead of entire address from memory map? secondly, how the hell do you learn all there stuff? since there are multiple libraries/tools.concepts used just for one problem. Impressive btw!

yes, yes.. of course i understand all this

Great!

Thanks for the Font LLL!!!!

Thanks LLL.

we finally got ghidra in dark mode

Can you make a video on how this would work when an application also has a DLL etc? ive tried this once on an application with a DLL and it got very confusing, really couldnt figure any of it out.

you are the best

Angr looks really neat. I suppose in some cases one runs into formal undecidability. How does it "cheat'"?

what if the binary was built in something else like Rust for example? whould then Ghidra reverse engineer it to C or to Rust?

this is some dark art shit- only able to follow a little of it, but interesting

Dark mode, let's go!

For anyone here new to Python, if __ name __ == "__main__": main() prevents the main function from running when you import the file/script somewhere else. If you call a function after defining it without this check, it will run even if the file is imported, which you usually don't want Edit: had to insert spaces between the underscores and name because YT thought I wanted it italic. In actual code, it would be 2 underscores, name, 2 underscores (no spaces between); sometimes read as "dunder name" (concatenating/abbreviating "double underscore" to "dunder")

I am looking forward, when we can take a binary and automatically turn it with AI in beautiful source code with comments etc.

Thx lll for zooming in

When running with correct permissions you can choose to disable ASLR for a spawned process which is likely what angr does. GDB uses the "personality" syscall to do this with the flag ADDR_NO_RANDOMIZE.

There's a piece of abandoned niche commercial software which I'd love to crack for archival purposes. Will this work on it? It's written in Delphi and it can be activated offline even though there was an internet activation option (which obviously doesn't work anymore). There is version 3.x which is still being sold even though there were no updates for 8 years or any activity from the dev whatsoever. Thing is, version 3.x is a joke. Well, 2.x was an actual joke, not worth a penny, and 1.x is the legendary version which I'd like to crack. I believe it would still be used today if the dev released a 64bit version like he promised :( The released version crashes way too often because of the ram limitation.

LFG!!!! LLG GANG GANG!

Now crackmes are cool but whos gonna actually have good info on compiling osx/xnu kernel, modifying kernel/writing a kernel driver to disable debugging detection, bypass address randomization. What for? Oh yeah, just to bypass debug detection and also have a way to dump consistent traces. And just to begin on actually getting progress with 20mb+ binaries
