How to REVERSE ENGINEER and HACK weak encryption - "SantaGoga" challenge [Capture The Flag Writeup]

The SantaGoga Hackazon CTF challenge writeup explains the difference between symmetric and asymmetric encryption, how to reverse engineer managed and unmanaged code, how to extract unmanaged code from a managed binary, how to create an RSA key using the p and q values, how to decrypt data using the openssl utility and how to use AES in python to decrypt a file!

🔥🙃🔥 Shout-out to the challenge author who changed the description after the audio was recorded 🔥🙃🔥

[@247CTF]

😭 Another shout-out to my video editor software which rendered out the crytpo-hack glitch animation 😭

[@_CryptoCat]

love this! so well explained and clearly presented 😻 video chapters would be a cool addition 😉

[@247CTF]

Noted! Is there an "easy" way to do it? Or you just re-watch your recordings and add timestamps after uploading?

[@_CryptoCat]

@@247CTF i've got into a habit of noting down the timestamps as im recording but that might not be the best option depending on how much post-editing you need to do. you can also rewatch recordings and add the timestamps, i went through my old videos and did that.. just make sure you start the chapters section with "Start - 0:00" for them to register properly 😉

Awesome! "throwing around math and greek letters" hahah

Amazing work!

[@247CTF]

Thanks a lot!

You are the best dude!!

Thanks! Keep coming back!

[@Dtomper]

What difficulty would you personally give to this CTF??

[@247CTF]

The CTF had a number of different challenges, I would say it was beginner-medium difficulty

hey can u make some reverse enginnering videos for beginner seiries your teaching method is crystal clear😍❤🔥

[@247CTF]

What would you like to see in the series?

[@sp3ct3r71]

@@247CTF this is jus my reccomendattion. use these topics to make your reverse engineering beginner to intermediate tutorial series 1 video -> introduction about reverse engineering 2 video -> little tutorial about c programming language(low level) and assembly instructions 3 video -> video about cpu architecture (x86 , x64, arm e.tc...) 4 video -> tools that could use to reverse engineering 5 video -> difference between static and dynamic analysis 6 video -> practical reversing tutorial with ghidra , ida or olly etc.. this is just my criteria use more suggestion from your subscribers and add your critirea to make this tutorial so interactive.. i beg you to start this beginner to intermediate revesing tutorial series cuz there is no proper reversing tutorials in youtube with proper order.. your explanations are clear and presenting method is so good.. i hope u got this chief^_^

[@SniperShadowGhost-mv3qz]

what this program called ? 7:13 i am searching propman and nothing shows up

[@247CTF]

sysinternals procmon

[@DarkAngel-ov2fu]

this is exactly similar to htb cyber apocalypses > alienware challange

[@247CTF]

Cool! Often you will see similar themes for types of problem, but a different implementation.
