Challenge of Reverse Engineering

Hello This is my 5th keygenme, that protected with crypto Rules: No patching, only keygen Some serials Name: Test Serials: B425B85539F77DD6CDC9A3C9A6F1058185C0EDA3A129F9B5131905FB609E51AF E064EA167E6891E84DCC7F7C3942EA3FB86AAC84B3DCA3CF6C1686FE24122681 3D90A4C48CF09B897A92EA7AEC1B5CA2115806F468CA2B1277D620CF78CC36B9 keygenme.rar

Hello This series started for the ones trying to learn crypto cracking. Please solve #1 first and then try this one and the following series. Notice: this is crypto 4 newbies and is growing in difficulty as you walk into higher series. Enjoy this crypto 4 newbies #2, and notice: -No patch -No serial fish -Stand alone keygen only! Hint: Differently from #1 this crackme contains also standard ****. 456.zip

The best solutions will win free entrance to "Malware Analysis: Methods and Techniques" training, which will take place during Ekoparty 2011 (http://www.ekoparty.org/) Requirements for the solution: Explain how the crackme itself works, not the validation algorithm [5 points] Find the serial for the username "ekoparty" [1 point] Make a keygen, preferrably in a high-level language like Python [3 points] Make a loader or patch to accept any serial [1 points] - Optional More information and download: http://blogs.eset-la...-ekoparty-2011/ Disclaimer - I am in no way affiliated with ESET.

I tried to make an application Crack me, and I insert the Serial Original. is there any other series, besides that? ... and if you can give me sourcecodenya with Delphi, BCB I'm still learning ... Asssembly I do not understand at all. Thx B4 ... Note: I'm not a cracker, I Just Want to Learn More than I can today!. CracKMe.zip

Hi mate, try this UnpackMe Enigma v2.70.20110629 Hope you enjoy this one LCF-AT waiting for this Enigma.Protector.v2.70.20110629 UnpackMe.rar

Here's another KeygenMe for you. Not hard, but not that easy either. Hope you'll like it. KeygenMe15.zip

A KeygenMe in C. My second keygenMe written in C. I've tested for bugs & fixed the ones that I found. If you find any others, please report them. Standalone Keygen is the ONLY soln. A Tutorial (in the form of text) or video can be posted as a BONUS. Level : You Decide! Solved By : --- --- --- --- --- --- Download KeygenMe.rar br KKR

Hey friends, Here is a new KeygenMe with GUI and no frustrating music, coded for newbies. Implemented some basic crypto, so they can learn something. Rules are common and yet simple : 1. No fishing 2. No patching 3. Only a valid keygen with tutorial and source are welcomed Hope, to see a good solution with a tutorial.

IntelliProtect v2.15 without trial and key. tested on all systems IntelliProtect v2.15.rar

I've written this one long time ago, just found it in my archive. Worth to give a try! BTW NO BRUTE FORCE! Keygenme.zip

VProtect is a new Protector by cooolie. This is the unpackme for you to test. />http://fs.unpack.cn/?fs=0&u=80 test_VP If you are interested, here is the download address of DEMO version. http://www.vmprotect.net'>/>http://www.vmprotect.net/demo/VProtectDemo.rar'>/>http://www.vmprotect.net/demo/VProtectDemo.rar And here is the official website />http://www.vmprotect.net

Well, it's been a while since I've been in the crackmes.de scene, so I decided to come back with yet another crackme. This one is just a tad bit harder (besides, everyone loves games). I decided not to enable any outsourced protections (obfuscation, etc...) because I want people to focus on the encryption routines and learn what to look for. Rules: (*) No Brute-Forcing (*) No Patching (*) When solved, please submit a tutorial and valid keygen For tutorials, tools, and help on ALL RCE topics, please visit BlackStorm Reverse Engineering team at: http://portal.b-at-s.info Greetings to Kurapica, revert, Apakekdah, SRC, lena151, obnoxious and everyone else contributing to Bla…

KeyGenMe #5. It's coded in VB.NET. Features : (*) NOT Packed (*) NOT Encrypted (*) Kool GFX 'n' SFX The Rules : (*) NO Patching (*) NO Brute-forcing The Tasks : 1. Find the algorithm for the computations involved. 2. Try to get Status as ":-)". 3. Make keygen to VALID Key for ANY name. Please note that VALID KEYS EXIST FOR ALL NAMES. Keygens able to generate multiple keys for each name will be preferred. KeygenMe #5.zip KeygenMe #6.zip

KeygenMe written in .net Crack the algorithm and write a keygen for it. Download link: />http://www.mediafire.com/?rk3zoctej3az99a The only rule is : - No Patching!

Hello This is a simple unpackme just for testing some features. Please try to unpack and rate its difficulty with a number between 1 to 10. in this unpackme we have : [+] Advanced Anti-Debugger [+] Advanced Anti-Attach [+] Stolen OEP [+] Nanomits Protection [+] IAT Protection [+] So simple Code Obfuscation ( Will be better in the future ) [+] Code Section Protection [+] Basic Anti BP [+] Memory Protection [+] Very Basic VM ( Will be better in the future) [+] Resource Protection Please Unpack it and write a little tut. Thanks.

Hello, This is my second keygenme and it might be harder then my first one. --- Information --- Protection: MD4 + MD5 Difficulty: Easy / Medium / Hard (Depends on your experience) Valid Solution: Keygen Only. (You can't provide any valid serial here, you will find out once your checking the keygenme) --- Other --- - Yes, this uses some loops again. - Yes, it has some pointers to the name. --- Download --- You can download the file here just in case something goes wrong with the attachment.
