Challenge of Reverse Engineering

Hey all, This is my first and probably my only KeygenMe. I wrote for a friend who's into VB apps (I haven't written VB6 in years). It's an easy algo, I just tried to eliminate sting searches and compares to show there are others ways to get to the routine. For anyone who keygens VB apps this should be pretty simple. It's not protected & compiled in native code. Have fun. Let me know what ya think of it KeygenMe#1.rar

hi,this is Zprotect 1.4.9.0 With key protection I put the project into the documents and registration documents to the unpackme file http://filebeam.com/aff2978f8e698239cbc57af512c42d60 Zprotect__1.4.9.0.rar

hi my friends it's an advanced KeygenMe that written in Adoube director. Try it. Download: />http://hashem20.persiangig.com/Learn/KeygenMe.rar

Hi please unpack it and write tut if it is possible ver :4.2 demo app:vb.net requirement: dotnet framework size:65 kb protection: almost all option thank you UnPackMe_Reactor4.2.rar

After some coding for my team, I got an idea abt a type of protection. I did my best to implement it in here. Its not very hard, but you must understand the math involved in it Best OF LUCK Regards KKR Download the challange from attachment : TERMiNATOR.rar .:Solved By :. 1) Saduff

Hey guys, This is too simple, so plz just make keygen... don't post any serial ! Cheerz KGM5.rar

Rules : No patching. : No Bruting. Keygen is the only soln. This will be a tough nut to crack. Download VoLtAgE_KGM.rar />http://www.multiupload.com/GKJX1MO8AZ If ya r not a crypto geek, dont even bother.

I wonder if the EC HID Protection could be reinforced by noobyprt, well u can check it: Crackme9.zip

Hi This is my last experiment trying to combine VMP Protect i think . not very strong , but for some poeople could be funny CrackME8.zip

Hi Again testing with VMP combinations layers, this time with Execryptor HID Protection Check it and rate it CrackMe7.ECVM.zip

Hi all. Protector option: Level: Maximum protection Virtual machine count: 1 Debugger detection: User mode + Kernel mode Write a tutorial ,If you unpacked it. Good Luck UnPackMe.rar

I hope this time the crackme has integrated the two layers in a better way than my first attempt.. VMP over ZProtect HID have fun CrackMe2.zp.vmp.rar

Well, I been experimenting with writing a little pet VM, just for fun, and I plan on releasing little KeygenMe's as I add new features. Right now it supports quite a few op codes, though not all of them are used in this algo. The EXE is not compressed or protected and it was compiled without optimizations, so it's just straight reversing. I kept the algo simple so that the focus is mainly on actual reversing and figuring out how my VM works. If there's any problems with it, let me know, thanks! Well, have fun! And here's an example key: Name: Hyperlisk Serial: 1C3A-FE0A VM.zip

Hello all, I stumbled upon this antidebug trick on my 64 bit windows 7. I now want to see if it works in 32 bit on any other OS. Can you guys please download and run this exe in and out of a debugger and tell me if it detects your or not? I would like to see if this antidebug trick is platform specific or not Thanks! -rendariAntidebug_Test.zip

This is a keygen me I wrote for my team (RED CReW). Thought of sharing it with every here.. The rules : KEYGEN is the only soln. No patching is allowed. A tut on it would be gr8 Download KGM2.rar http://www.multiupload.com/VPE0JDTC5K For some odd reason I cant attach any files !!! Hope posting a link is not against any rules

here is a crackMe NoobyPrt+Res PCked Execryptor I hope this doesnt have the slow run issue Test it

Hi there! I'm just dropping another keygenme for you. This time, please make a keygen Have fun! jensma.de/keygenme_jensma_2.exe For everyone who encounters difficulties, here are some hints: The program searches for a file called "key.file". The serial isn't hardcoded. keygenme_jensma_2.zip

This maybe too much easy for our very fast unpackers Enigma 1.68 HID Protected and Code Packed with Execryptor. CrackMe5.rar

Hi I hope this CrackMe be a little more intersting: Packed VMP over a Themida KeyFile Protection Objetive: Run Without Key key included in the attach Some issues with AVs, but the file is absolutly clean (Same file used in my others crackmes) CraCkM.rar

Under SEH Team Keygenme 11 LeVeL : 3/10 Rules : dont patch or serial fish it . Just make keygen! Keygenme.v11-UST.rar Mirrors : http://ustpre.zzl.org/kgme/Keygenme.v11-UST.rar http://stashbox.org/881536/Keygenme.v11-UST.rar Have A Good Day GioTiN ^ UST
