pavler on 2024-05-27 14:39: "lockcmpxchg8beax" - think it would be a bit harder, solved in 10min literally

justAuser on 2024-05-27 17:10: lockcmpxchg8beax Though got bsod when I went in too deep (went verz deep) :"D

justAuser on 2024-05-27 17:15: Btw is this you? https://github.com/cutemastermind?tab=repositories "What can I say..." :D

imeow256 on 2024-05-28 10:50: congrats guys didn't expect you to crack it with such rapid! yeah @justAuser thats my github profile lol :D

Kache0 on 2024-05-30 19:37: yeah lockcmpxchg8beax its just there in plain text

imeow256 on 2024-06-01 09:49: @Kache0 what are you talking about, what tool did you use to find it in plain text?

Barimor on 2024-06-01 15:47: It was awesome, but I thought lockcmpxchg8beax☺ it isn't a password.

cnathansmith on 2024-06-04 07:16: @imeow256 It just directly compares the input to the deobfuscated password .text:0000000140018F95 mov rdx, [rbp+230h+Str2] ; Str2 .text:0000000140018F9C mov rcx, rax ; Str1 .text:0000000140018F9F call j_strcmp You just break there and check the arguments and there isn't really anything to solve

imeow256 on 2024-06-04 11:17: @cnathansmith ohh shit i fucced it up then

survivalizeed on 2024-06-06 13:26: [Click to reveal]

imeow256 on 2024-06-08 17:56: @survivalizeed could you give me some advice or a better way to check for correction?

MouadDS on 2024-06-09 15:57: solved in less than a minute (im a starter)

Hapten on 2024-06-25 22:49: @imeow256, is it possible you could make a video, or just somehow explain how am i supposed to deobfuscate everything after "Enter password" and overall get the password.

survivalizeed on 2024-06-26 13:12: @imeow256 there is not the ONE way of doing a good obfuscated compare. I highly encourage you to take a look on virtualization tools and how they work. Tigress/VM Protect have some nice devirtualization blogs you can learn a lot from :)

imeow256 on 2024-06-27 12:54: @survivalizeed thank you i will definitely take a look!

Keep on 2024-07-23 21:49: cant find the password with ida, dbg, or dnspy this program is objectively horrible

newport on 2024-08-15 16:41: string references isnt there, i dont think theres obfuscation i tried x64dbg and ghidra and neither could figure out where it is. patching did NOT work sadly (im a patching man)

Ja4V8s28Ck on 2024-09-16 07:36: I'm typing my doubt here because no one seemed have to noticed it yet,this program requires internet to work, I wonder why. I use a sandbox with restricted network access to do these crackme's and when I tried to run the program it always puts an error. This error is only seen in this program so far. ``` [ERROR] Failed due to error: 823L [ERROR] Failed due to error: 356 ``` Can @imeow256 please clarify why I'm getting this error And to the imbeciles who are posting answers on the comment section, please flex your knowledge by writing a good writeup to help the forthcoming people. Your answers are not helping anyone, not even yourself because it only proves that you are unworthy showoff.

Ja4V8s28Ck on 2024-09-16 08:39: after a deep dive, I realized the program downloads "Project1.DLL" from your personal repo and saves it in the `%userprofile%/Documents` and cleans it up after the program exits. Can you please add the project files inside the zip file rather than downloading via the internet in your future projects?
