Your goal is to Crack the File and make a Tutorial or Write Instructions about the Steps done by you.
 
What is Xamarin?

Xamarin is an open-source platform for building modern and performant applications for iOS, Android, and Windows with .NET. Xamarin is an abstraction layer that manages communication of shared code with underlying platform code. Xamarin runs in a managed environment that provides conveniences such as memory allocation and garbage collection.

 

This is my first crackme, so I may have screwed up some things, but overall it should be a fun challenge. The file is protected with my own packer/obfuscator, Titanium, and compiled with pyinstaller. Read the readme before reversing.

It is written in FASM, anti-debugging methods are used.
You need to get the keys that were used to encrypt the hash being checked
(Enter the necessary values in the input field to get "Success", and throw these values here)

Vmprotect 3.4 & Custom OB
Vmprotect anti debug and VM protect is disabled
Find the way & explain how 

Provide a key and send a cleaned executable.

Language: C#(.Net)
Goal: to get the key of obfuscated file
Key on the screenshot is wrong, you have to crack this CrackMe and send key with tutorial on how did you do that.

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!

This is my clumsy virtual machine 😃
Goals:
Bronze - Patch the crackme to show the correct message
Silver - Bronze + explain how the virtualized code works
Gold - Silver + write a totally different virtualized code to pass the check

Brand new obfuscator on the market.
I've already completed this crackme but wanted to see what you guys come up with.
Good luck!

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.
 

This has an anti-debugger which will constantly look for strings that'll contain the name of debuggers such as De4dot and more..

Hi guys , i write a very simple crack me , i really do not know how i should secure my code just write a very basic one . anyway i know it's very easy but still wanted to know other peoples opinion. if it did not run please let me know , i did not use any packer , or protector , just my own code , and it's written in C++ with visual studio 2019 on windows 10.

Try to find the key. Hint, the key contains:
Specials Caps Non caps Numbers Enter the key and you will see the results. Good luck.

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.

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.
 
 

This file is protected by my custom C++ virtualizer and C# protector.
The correct solution is to find the correct key and unpacked target.
Enjoy it!

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.
