Example CrackMe - Debug Blocker x64
By Teddy Rogers
This is an example for submitting a CrackMe in the Downloads section of the site.
You can download the file and run Debug Blocker x64. Nothing too exciting will happen!
The challenge here would be to patch the debug-blocker function so that it does not spawn a second process.

Python Patchme (Custom VM) (UPDATED v1.2)
By svenskithesource
Hello,
Since the use of vm's is quite popular in .net obfuscation I thought it would be interesting to make one in Python. Hereby I release my first crackme using my VM. It's a very simple VM so it shouldn't be that hard to reverse with the right knowledge.
This is purely experimental to see if it would be useful somehow. I also used my own protector that adds cflow, so expect to see a lot of jumps.
Goal: Patch it (ultimately devirtualize it, but that's not necessary)
EDIT: This is now updated. I tried to make sure it isn't possible to patch with 1 or 2 jumps.

Tricky
By LoLLo90
Goals:
Bronze - Patch the crackme to show the correct message
Silver - Bronze + explain what is happening
I don't know why Windows Defender is giving a false positive. My past here should prove I am not here to harm anyone.
I only used Appfuscator for renaming. I checked the file and I did not see any other obfuscation or anything annoying automatically inserted by Appfuscator (like outline method calls).
Please extract all the files in a folder to make the exe work properly.
Let's fight!

CheckMePlease
By CodeExplorer
This crackme is created with Qt v4.8.4,
The goal of this crackme is to make the CheckBox checked,
not to only pass the check when the Check button is pressed.
There is also the options of creating an program which will change the state of CheckBox.
I don't think is trivial task: I can't even enumerate windows.

A Crackme with Math Problem
By wwh1004
Just run it. It is an interesting math problem. No vm, no obfuscation. You can debug it with dnSpy even Visual Studio. You should use public method inside this crackme to generate a valid hex string and make program output correct string.

Poetic AutoIt (string/integer obfuscation)
By SimplyMercurial
This is a simple CrackMe consisting of an input. The correct input is two stanzas of a particular poem and will reveal a label of the poem title and author upon success. Otherwise, "Try again..." will be displayed.
If I'm allowed to be picky, I'm primarily interested in scripted efforts to RegEx analyze strings/integers. Very little effort (as in none) went into hiding the correct string. The script was merely passed-through a self-made obfuscator.
Full disclosure: It contains rudimentary debugger and compilation checks which, if failed, falls into a while loop with a one second sleep (harmless). But, as stated above, this isn't the focus of what I'm after.

CrackMeBoi
By Ninjego1
I made a custom obfuscator and I haven't made any progress cracking it so please crack the file with my custom .NET obfuscator.
Do not use OllyDbg or any software of that kind, you can use Mega Dumper and other tools similar.
