Please create a series of Reverse Engineering Basics! Love this!

Its like the perfect purity of a man page was compiled into a perfect video. Instructions so clear I accidentally cracked the travelling knapsack problem.

4:07 "a small popup will show up." popup occupies most of screen.

Crystal-clear, methodical and systematic walkthrough! Thank you!

Excellent explanation. Clear, concise and a great pace, wasn't confusingly fast or laboriously slow. I hope you continue to make videos on Ghidra.

wow this tutorial is just perfect, the pace the explanations, everything ! Thank you

Brilliant "in a nutshell" tutorial of getting to know the program quickly. Could you please do a follow-up of the very same crack me, but with showing how you "crack" the crackme by patching the binary inside Ghidra so that it always jumps to the success condition regardless of the input given?

I had a quick look at Ghidra a few weeks ago and it seemed rather complex.... It certainly seems a lot less complex now! Thanks.

Thank you Ghidra Ninja. You are a true Ninja!!

wow, nice introduction man. looking forward for more videos from you!

amazing man keep uploading ghidra tutorials

Thank you for a great overview. I'm getting started quite easily because of this 👍

Many thanks for suggesting this software ... I wanted to look into reverse engineering for years, but had not yet come across such an handy tool. AIDA wasn't really affordable for experimenting ... Again thank you very much!

Excelent. We want more!! Really good tutorials

Your videos are awesome! Please keep making content like this!

awesome tutorial - keep them coming man!

Thank you - and pls. continue the work. PS: made me smile.

This helped so much, the main thing I needed was just the fact that you can click on named functions in the decompile window to go to them. Seems obvious but I just didn't know!

Liked your explaination, easy and clear. Keep going please.

Love this. Keep up the great content man

very good video! Im already applying for NSA!

love the “NSA-Mainframe” on your terminal. I let out a good laugh at that!

For future listeners, Ghidra is pronounced, "Gee-druh"; [3] /ˈɡiːdrə/[4]). Source: github.com/NationalSecurityAgency/ghidra/wiki/Frequently-asked-questions#how-do-you-pronounce-ghidra Great video, and well-explained usage. Keep up the great work.

That's a great tutorial man ,thx!

Great content, subbed, keep them coming!

Excellent video! Is there a way to isolate and tag raw binary into separate chunks? For example if you read an EEPROM and load it in Ghidra as raw binary can you then split it up into prgrogram, data, etc so that decompiler can make sense of it?

love it bruh... keep it up

Very good tutorial

Amazing tutorial

Just curious as I just learned that this tool exists, what is difference using this vs ollydbg for cracking? Other than assembly

great !!! Please, more !!!

Thank you for this video!

Great video! You explain things really simply. One question I have: can you use Ghidra to compare two similar .dll written in C++ files to find the differences between them?

THANK YOU FOR DOING GOD'S WORK!

nice intro! of course, there's any number of possible solutions given that the only criterion is an @ in 5th position

Thanks man for the knowledge you are awsm

Great video. But could you make a video comparing Ghidra to IDA or some other RE tools?

Great, really great !

Waiting for more videos from you.

Thank you so much!!!

my terminal doesnt allow me to open the crack me initially, you said you're using a VM, is that a different terminal than mac's default?

Love it.

Great tutorial, kudos! Can you elaborate why is there an issue requiring the usage of a pointer to a pointer for argv ?

Approved for 100k.

Could you please make a tutorial on how to skirt the Mac OX Catalina 10.15.8 and download Ghidra? I really want to start using Ghidra but my mac will not allow the Javascript updates ...

Kind of a dumb question but how did you get your keystrokes to show up on the screen like that?

How are you able to run the Unix binary file. Im getting: ```zsh: exec format error: ./rev50_linux64-bit```

More tutorials please!!!

Nice video, but I have a question. Is it possible to get the flag without putting the password? Since the flags stored somewhere within the file, right?

Because Ghidra unfortunately does not support [] in the function signature - so instead of saying 'this is a pointer to an array' we say 'this is a pointer to a pointer', which gives us the result we want :) (Simplified: Working with an array in C is basically just pointer-arithmetic in the background)

What VM do you use for running Linux code in OSX?

nice

Is there a way to find what part(s) of the program are referencing a data-text string? I've tried doing a global search of the address, but where can I find the functions that use it? I've looked at the tutorial 'Z0FCourse_ReverseEngineering' from stryker2k2/ wolfshirtzlabs but don't see that covered! Very new to this, would OllyDbg or IdaPro be more beginner friendly?

I'm a normie, no govlarp here, IDA is the only one I've heard of, Would be interesting to see how file analysis programs are built from scratch, as well as what language they would have to use to build a file analysis tool like ghidra or IDA Ghidra is kind of esoteric, IDA all the normies like me will recognize I know the govlarp people like using python

Could you do a little tutorial using a MSDOS 16bit binary file? Maybe something that's not packed?
