NanoButton
By Bang1338
A follow up of TinyCrackMe
Challenge:
- Press the button "Hi"
- If correctly bypass, a MessageBox with `:3` show up.
Rules:
1. Patch? Here's a deal:
- No patching if you're unpacked UPX, as final result!
- Allowed patching if you're not unpacked UPX, as final result!
- only patch-fix the flaw like missing stdc dll, or temporary byte patch to making loader or hook
2. Spoiling? Yes! (originally in crackmes.one is "no")
3. Keygen? useless. Because the goal is bypass it!
4. Hooking? Allowed! It's not a patch!
5. Loader? Allowed! It's just a mem patch, not file patch...
6. Any these above, do not use any tool to create stuff like Baymax or dUP2, but you can create your own one with coding.
Happy Reversing :3

CrackMe with Anti Patch
By Nisy
The program uses VMP protection, and calls the relevant checksum SDK, even if the violent crack may also be slightly more complex, here provides a baymax patch tool to achieve the crack program, interested friends can read the pdf tutorial.
The function of the program to determine whether the input is correct or not does not use the SDK for protection, and verify the error dialog box strings are searchable, but these do not mean that it is easy to crack, because the code also calls the memory checksum, determine whether the debugging and other SDK interfaces. So how to realize the cracking of this crackme?
Baymax Patch App Protected by VMP is a PDF file, The detailed cracking process is explained above and can be consulted if you encounter difficulties while analyzing it. The PDF is divided into two volumes, the lower part can be downloaded from the Authors Solution section.
Attached is the source code of crackMe, the bpt file is the corresponding crack project of baymax64, you can use baymax tool to generate the corresponding patch file to test and verify the effect.

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.
