| Very hard antidebug +10 antisystem | As ilkiNUR stated, the correct password is in plaintext which made trying to circumvent the anti-debugging checks unnecessary. Here's my writeup: https://bobbyhillreverseengineering.blogspot.com/2025/11/crackme-bobxs-very-hard-antidebug-10.html Thank you for the challenge. | 2025-11-08 16:15 |
| Hacker's Edge Book CrackMe v3 | On 10/16/2025, I tweeted at him on X and he added the section to redeem the book with the promo code. I was able to place the order but I have yet to receive the book or any updates regarding it. I sent him a DM on 11/02/2025 to ask about the book but he has not responded. As of today, the link to redeem the book via promo code now responds with an error message. I have sent him a follow-up DM today(11/07/2025) to let him know about the error page. If I ever receive the book or a response, I'll add another comment but as of now, it isn't looking too good. | 2025-11-07 23:20 |
| Assembler Crackme | Thank you for the challenge. If you want to make it more challenging, obfuscate your function/variable names or strip symbols completely. Other than that, I appreciate you taking the time to write this, especially in assembly! Kudos.

| Hacker's Edge Book CrackMe v3 | Woot woot, I think I got it! I normally write blog posts but as there is a reward involved, I obviously won't be doing that this time around! Thank you for the challenge Ryan! | 2025-10-14 21:57 |

| Very easy disassembly execise | Glad I wasn't the only one who thought the way arguments were being passed was strange. @iwannabecoder, open a command prompt and navigate to the directory you're storing the crackme in. Then execute the program using the command prompt. cd /Downloads crackme.exe When your password is incorrect, you will not see any output.

| Patch protect lite | Dang, everyone has done a fantastic job of breaking down the key generation algorithm. I was thinking of working on a keygen today but it looks like it's already been taken care of. Any who, I took a similar approach to patching the program.
