Introduction to Reverse Engineering

[@goonchik]

As someone who is just beginning their journey that was extremely informative!

[@mettek88]

Absolutely ... we want another video like this! :D

been working as a developer and recently have developed a huge desire for exploitation and reverse engineering stuff.. this is good stuff.. thanks!

[@RokRoka25]

This video was super helpful! As someone slightly interested in game modding / hacking, this was the first step I've been looking for, so thanks :D

Nice, finally I can learn nerdy informations without going to physical classes, I extend to you my greetings!

[@pcsecuritychannel]

That’s all good but get some sleep though.

[@remasteredretropcgames3312]

My training begins soon. We need you Batman, or i will be forced to handle Gotham all alone.

[@remasteredretropcgames3312]

First step. Get certain filter effects to do their pass AFTER reshade so injections limitations are erased.

[@elviraeloramilosic9813]

Completely and absolutely YES. Great one Leo! Right topic & right tools. 🏆

For Linux users : they can use inbuilt tools as in strings ,file ,diff for various analysis . Debugger tools - GDB. Reverse engineering - Radare an alternative of ollydbg. Lastly great help friend .

[@airwaybill2000]

Please do the class 2, good to learn!! You are great teacher

[@TheawesomeMCB]

Oh so that’s how you get the first key! Tbh I never actually figured out how to get the key when we did the first challenge xD Wow this is intense to do! Edit: Nice video by the way Leo!

[@colin9481]

Very interesting for a lay person often wondered how it was done, Great video.

[@theguyfromtech4090]

So it's basically looking at how the application interacts with the computer processor at a low level, and executing blocks of those code to see the output of the program and understand it better? Nice, I definitely would need C or C++ to perhaps introduce binary and some basic memory concepts to me, and Assembly in order to understand the low level interactions of an application with the computer processor. Overall, I believe this is one of the many techniques I'll be introduced to, and I enjoyed eating while watching this video as it was very educational and interesting to watch, thank you.

[@kenb.1212]

Leo, Thank you for all you do on the PC Security Channel! Very helpful!

[@liorgeva9001]

Best video I saw this year so far. Thank you =]

[@markarthur1083]

I created a similar program in C and tried this and it worked. Key points that were left out in the video that initially caused me some trouble - set a breakpoint in OllyDbg, OllyDbg only works with 32 bit binaries.

[@Henk717]

Those challenges where really fun to both solve and make. I'd love to see more video's on them so the viewers can see how they where solved and what techniques where involved.

[@AK-up9vv]

I was waiting for someone to make tutorials on reverse engineering for so long. Thank you

[@chrisburn2117]

Been watch your channel for years on anti-virus reviews and alerts. I found this very informative and look forward to more. Keep up the good work

[@danbromberg]

Being new to reverse engineering, I'd enjoy seeing more content like this!

[@HazyJ28]

Very intuitive and I would LOVE too see more like this. Like with AES for example

[@hamadalkhalifah3003]

Ironically , i do study Computer organization now in my college and i always wonder why should we learn old language like assembly , well i guess i get the answer now . Thank you for sharing ..

[@AdobeAirpods]

Great vid, trying to expand my skill set with HTB

[@manhattan_9503]

something I'd love to see is bypassing antitamper/antidebug, there are a few plugins for olli which do this but a breakdown of how would be awesome

[@sjcambal1120]

Wow that video was so nice. Hoping for more content like that.

[@usta4070]

I'd like to see some RCE tutorials that would bring us old timers from the 1990's back up to speed and get us reversing again in a x64 environment Ie. 64 bit debuggers, dissasemblers and Packer identifiers. There's a big gap between the Lena151 stuff and how RE is done now and there's many of us out there that want to update our skill set with modern day tools. Thanks for the video.

Hey, Leo, can you do a video on the quote-unquote 'dangers' of HTTPS Scanning preformed by antivirus software? An encrypted connection ensures that the connection cannot be modified by anyone else, but it does not guarantee that the actual content being downloaded is safe. Just as with plain HTTP, if a legitimate website is hacked, malware scripts and binaries can be placed into the HTTPS page that appears to be safe.

hi, how do we find the right string if it's kinda coded? like when it doesn't say ,,locked" but something else instead?

How do you know if the password is internal to the program or if it needs to communicate over the Internet?
