Hi all, this is the second issue on symbian I release. This time thanks to argv I will concentrate on 4 crackme he developed. I will solve them and detail a lot of things that was left out of my previous tutorial on symbian. The result of this tutorial is a symphony of patches, crackmes and

Should you want to try out challenges other than those found within this forum you may be interested to know a number of other challenges can be found on Tuts 4 You: />http://www.tuts4you.com/download.php?list.49 If you are interested in unpacking specific protectors and packers (and their respective versions) you may want to check out the site archive: />http://www.tuts4you.com/download.php?list.60 Feel free to post your solutions to any of those challenges here in this forum. All successful solutions with an explanation or paper will then be moved to the Completed forum. Happy reversing... Ted.

Here are some papers about the still rarely commented .NET file structure. They'll surely come in handy, when u're dealing with .net reversing... .NET PE file structure + .NET Resources + Code for a .NET-Resources-Viewer: tKC.rar(All by tKC - big thx for it !!!) The .NET File Format: http://www.ntcore.com/Files/dotnetformat.htm (by Daniel Pistelli) .NET Manifest Resources http://www.pmode.net/USERS/116/Files/manifestres.htm (by Daniel Pistelli) Physical Layout of a .NET Assembly http://www.samspublishing.com/articles/art...=25350&rl=1 (by Kevin Burton) Greets

I couple of interesting papers going over a few topics which, are actually quite an interesting read. Articles are written by Daniel Pistelli and Ashkbiz Danehkar. The NTkrnl Journal, Vol 1, Issue 1 http://www.ntkrnl.com/company/pressroom/jo...krnlj_01_01.pdf The NTkrnl Journal, Vol 1, Issue 2 http://www.ntkrnl.com/company/pressroom/jo...krnlj_01_02.pdf Ted.

Hi, I dont know is this the right area for this, if not please replace it. Comptuter security & cryptography Cheers, SSlEvIN

Introduction In the next part of our serial we will focus on one of the most important parts of protection of every shareware program - secure generation and verifying registration numbers. On the proposal of this algorithm stands or fails a possibility of creation of crackers registration numbers generator to a program. Example algorithms in this article are written in Pascal. We think that almost every programmer should be familiar with this language or at least to some extent. A lot of programmers are not very careful when programming algorithm verifying and use algorithms like: function CheckKey(UserName, UserKey: string): boolean; var i: integer; Key: integer; begi…

Introduction This new serial will point out traditional mistakes when designing anti-cracking protections and will introduce methods on how to improve protection. In the introductory part we will focus on presentation of programs and techniques commonly used among crackers. Revenue loses of software companies, caused by illegal copying of their products are not trivial and most of the time exceed earnings. Insufficient or frequently absent software protection against illegal use is therefore startling. Many people I talked to regarding anti-cracking protection advocated this absence of anti-cracking algorithms by saying that it is useless, since „even though, someone wil…
