    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.

    WinLicense v3.2.2 (Window Function Through an External Plugin)

    By lengyue

    This is a WinLicense 3.2.2/sample, set by default, without adding an SDK in the source code, only adding a window function through an external plugin. I don't know if bypass can be cracked, I tested it and it doesn't. Shedding may be more complicated.Please use your own way to crack it. Whether it's molting, bypass, or keygen, they are all the best methods. No need to upload your proposal, posting a picture is the best answer. I will strive to learn towards your achievements.

    BinaryShield (Custom VM)

    By ra1n

    This is my first attempt at a binary protector. Currently, the VM has very little protection, so this should be good for those interested in learning about VM-based obfuscation. I intend on uploading new challenges that feature my protector as I add more features.

    GOAL:

    - You must find the correct key. Simply patching to get a goodboy message is NOT allowed.
    - Bonus points for devirt and explanation of your approach.
    - MOST IMPORTANTLY, have fun!

    :)

    VMProtectDDK v3.84 x64 No.2 2024

    By boot

    If you want to try this challenge, please read the following text descriptions:
    1. Please try to debug the kernel driver in the virtual machine instead of your real machine to avoid causing a blue screen on the physical machine
        a. Why blue screen? For things like Ring0.sys, as I mentioned earlier
        b. Copy the Tuts4you.ini file to the C:\Windows\ directory of the virtual machine
    2. I have added a test signature to the driver, so to load this driver, you need to enable Windows test mode
        a. Press and hold the "WIN+R" key to launch the CMD console as an administrator, enter bcdedit /set testsigning on
        b. Restart your computer
        c. After restarting, there is a prompt similar to "test mode" on the bottom right corner of the computer, indicating that it has entered test mode
    3. If you give up this challenge, you can choose to turn off the testing mode at any time
        a. Press and hold the "WIN+R" key to launch the CMD console as an administrator, enter bcdedit /set testsigning off
        b. Restart your computer
        c. After restarting, there is no prompt similar to "test mode" on the bottom right corner of the computer, indicating that the test mode has been turned off and entered normal mode
    4. How to load this driver?
        a. Use DriverMonitor to load this driver
            i) Download DriverMonitor from here
        b. Run Ring3.exe and click on "Open Device"
        c. Use Dbgview to view the corresponding debugging information and whether to output Flags
            i) Download Dbgview from here
    5. Please note:
    Due to *.sys being protected by VMP, unlike *.exe or *.DLL files:
        a. This means that you cannot directly debug it using x32/x64Dbg or OllyDbg
        b. This means that there is no ready-made script/unpacker or one click cracking tool
        c. This means that you need to manually use windbg for debugging
    The ideas you can try are:
        1. Use Windbg to debug Virtual Machine
        2. Patch HWID -> Allowed! You can try to do this
        3. Unpack this kernel driver ->  Allowed! You can try to do this
    Verify if this challenge has been resolved:
        1. Provide me with the content of Flag1 and Flag2
        2. After patch HWID or Unpack, ensure that the driver's image or dump file can be loaded, and remove VMP protections, which can directly output Flags
    If you have already solved this challenge, please create tutorial(s).
    boot @ Tuts4you
    -------------------------------------------------------------------------------------------------------
    Reminder:
    1. Please do not try on the physical machine, please be sure to try on the virtual machine.
    2. Turn on testing mode and restart the virtual machine.
    3. Copy Tuts4you.ini to the "C:\Windows\" folder.
    4. Operate according to my video.

    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.
