I made a simple anticheat, extending my crackme project.

This uses no mutation whatsoever, and is only a game of logic and reverse engineering skills.

Edit: I should mention that if you do get detected, it'll print why you got detected in the console. Use this to your advantage!

GOAL:

call the function printing "hi!!!" under your own thread, or redirect it to your own function

or just reverse the checks, I'll also count properly reversing it as a bypass.

RULES:
all anti cheat initialization's are in the main function, you can use these to reverse however you CANNOT patch the calls in main.

That's it, anything else is allowed as if it were an actual game.

piss easy, already reversed it using my AI made application and patched all of your checks, switched out every function and patched every silent checker you have created.

Get good, 0x90.

-dynamic_cast.

[EDIT] Before you ask how, I just hooked RtlpCallVectoredHandlers and made sure LdrSetDllManifestProber didn't also redirect, too easy lol try harder

@0x90 you simply seem to not understand how f*****g brilliant I am, I prove you wrong and you start to create some junk code and throw it out in the wild for skids to think that's actually how you start it? Pahaha! You're pathetic.

@Bones He is so smart yet is really respectful and gives tips and suggestions on code and would never insult anyone. He is also modest and does not attempt to tell everyone how good he is.

We should all be like dynamic_cast.

This is satire and is not legal advice. Please consult your lawyer if you wish to be like dynamic_cast. Also probably your doctor, cause why would you wish to be like dynamic_cast.
