Challenge of Reverse Engineering

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

here is a link to my latest crackme, again written in Visual Basic 6 using a custom protector i've written specialized for any VB6 application. Protected.rar The goal is simple... get the good boy message by entering the correct serial... A note of warning, if u manage to find a valid serial do NOT post or share it anywhere as it will stop working if a share is detected. Simply PM me here or at ARTeam with the serial you've found/made and i will verify A couple things to note: Avira detects it but it's not a virus... contains simply 3 calls to a msgbox and the call to the verification routine and must be allowed thru your firewall for the server check To further sh…
