Using OllyDbg to log dynamically loaded functions (the easy way)
Written by Ksbunker | There are 0 comments! What is the easy way? Read on.
For there to be an easy way, surely there's a hard way? Yes, hooks. They're redundant in this case... why complicate the process!?!
What's the easy way? Conditional log breakpoints.
Example.

Zone Cryption (Final)
Written by RANCID | There are 0 comments!Out of bordom, I decided perhaps this may interest someone. I have no use for this knowlegde any longer as their is no Zone left, just a pathetic mess of a flash gaming site.
Bypassing HOOK's
Written by Ksbunker | There are 0 comments!This article is written in follow-up to Specific's "Hook process functions via dll injection Cpp". His article detailed how to hook functions using an injected DLL. Expanding on this concept, i'll detail how you can trampoline over the CALL or JMP instruction which forwards flow to the hook function; effectively rendering the HOOK void/useless. This method works well with any application that attempts to spy on or intercept specific functions, e.g. WPE, TrainerSpy, etc. The code is in ASM but generic enough to be ported to any other language with minimal fuss.
[ASM] Training DLL's
Written by Ksbunker | There are 0 comments!Unlike exe's, dll's do not always get loaded into the same address space (i.e. 00400000). This address is called the 'Base Address' and is a pointer to the "M" in the "MZ" signature (which is if you dont know, is the first two bytes in any portable executable [i.e. exe's and dll's, any some other files]).
[ASM] Simple yet effective parity/integrity protection
Written by Ksbunker | There are 0 comments!I post this here because, lets face it, zonehacks is all about doing things we wern't meant to be able to do, exploiting, etc... it all comes to security. The following code is written in asm, however, it can with very little work be ported to any language, at least that's the intention.

Injecting a DLL Using the Registry
Written by Specific | There is 1 comment.If you've been using Windows for any length of time, you should be familiar with the registry. The configuration for the entire system and most software is maintained in the registry, and you can alter the behavior of the system by tweaking its settings. In this tutorial of how to inject a DLL using the registry, the entry I'll discuss is in the following key:
*Note* Windows 98
Windows 98 ingores this registry key, so you cannot use this technique to inject a DLL under Windows 98.

Hook process functions via dll injection Cpp
Written by Specific | There is 1 comment.This tutorial on how to hook process functions via dll injection is not for the beginning programmer. I assume that you have knowledge of creating DLL (Dynamic Link Libraries) files in C++, as I do not cover this. If you do not know how to inject a dll into a process, please read my tutorial "Inject DLL into running process with CPP."

Inject DLL into running process with CPP
Written by Specific | There is 1 comment.What is the purpose of injecting a DLL into a process?
Injecting a Dynamic link library (Dll) into a process can be used for many things - that is, it's up to the programmer what they want to do. Dll injection is most normally used to hook API in the process, however, it's often used in game hacking to redirect method calls within the game or application to the programmer's custom functions.

Usermode tricks for calling WriteProcessMemory
Written by Ksbunker | There are 0 comments!This information is nothing new, but I think it's very interesting none-the-less. Given the prevalence of hooks (detours, hotpatches, IAT hooks) in todays scene, it is becoming more important to understand how to circumvent these rudimentary attempts at slowing us down.
Hooks have been spoken about ad nauseum here at zonehacks so I won't explain what they are or how to use them... this is all assumed knowledge (and if you're still uncertain, just browse over Specific's articles). Besides this article is not about hooks per se, but rather how to call function without executing the modified (hooked) line(s) of code.

The Trojan DLL Injection
Written by Specific | There are 0 comments!The title may have caught a few readers thinking, "What the hell is this Trojan DLL?" Trojan DLL injection is another way to inject a DLL by replacing a DLL that is known a process will load. For example, if the programmer knows that a process will load customapi.dll, he can create his own dll and give it that same filename. Of course, the programmer must rename the original customapi.dll to something else.
Posting Messages to a Thread's Message Queue
Written by Specific | There are 0 comments!Once a thread has a THREADINFO structure associated with it, the threrad also has its very own set of message queues. If a single process creates three threads and all these threads call CreateWindow, there will be three message queue sets. Messages are placed in a thread's posted-message queue by calling the PostMessage function:

A Process's Virtual Address Space
Written by Specific | There are 0 comments!Every process is given its very own virtual address space. For 32-bit processes, this address space is 4 GB - that is, a 32-bit pointer can have any value from 0x0000000 through 0xFFFFFFFF, allowing a pointer to have 4,294,967,296 values. For 64-bit processes, this address space is 16EB (exabytes). A 64-bit pointer can have any value from 0x0000000'00000000 through 0xFFFFFFFF'FFFFFFFF, allowing a pointer to have one of 18,446,744,073,709,551,616 values.

Your First Java Program
Written by Specific | There are 0 comments!The objective of this tutorial is to introduce object-oriented programming and how to apply object-oriented thinking in program development. our first Java application displays a window on the screen. The size of the window is set to 300 pixels wide and 200 pixels high. A pixel is a shorthand for picture element, and it is the standard unit of measurement for the screen resolution. A common resolution for a 17-in monitor, for example, is 1024 pixels wide and 768 pixels high. The title of the window is My First Java Program.

Making a back button with Javascript
Written by Specific | There is 1 comment.When creating a website the creator must remember the user and their need to know where they are in the site. Users can easily get lost within the site's navigation and not remember how they got where they are. A simple way to fix this without adding a full breadcrumb system like we have here at zonehacks is to simply add a way for the user to travel backwards through the pages with Javascript.

Using Heredoc in PHP Strings
Written by Specific | There are 0 comments!Strings can get really complicated the bigger they get in PHP. In order to allow people to easily write large amounts of text from within PHP, but without the need to constantly escape charactors, heredoc was developed. Heredoc might be a little tricky to understand at first, however, it will help in the end. It allows you to define your own string limiter so that you can make it something other than a double or single quote.

XSS Holes
Written by Carb0n | There are 0 comments!In this article I will give you a general idea on what an XSS Hole is and how it can be exploited.
First off, XSS stands for Cross Site Scripting. Basically, that means one site loads a script onto another site that it is not affiliated with (a site that has a different domain). Normally, cross site scripting is not intentionally allowed by the host site because this allows a 3rd-party site to potentially access a user's session information and other important user variables on the host site.

Search Engine Friendly URLS for Dynamic Pages
Written by Specific | There are 0 comments!Introduction
When creating a dynamic website, URLs can become messy and very complicated. This creates two problems - that is, the URL is not user friendly or search engine optimized. The URL will not be user-friendly because it is full of variables, strings, and ids that can be hard to remember. Search engines do a pretty good job with urls, however, they can get confused. One of the most frequent questions web developers ask is "How can I change my dynamic URLs to static URLs?" The procedure to implement search engine-friendly static URLs for a dynamic site is pretty simple. After reading this tutorial you should be able to take a URL like the following: www.yoursite.com/?page=5 and make it something like www.yoursite.com/search-engine-friendly-url.

So how do you center a layout?
Very easy actually. . . .
Create a layout using CSS
Written by Specific | There are 2 comments!In this how-to article I will cover the basics in how to create a layout using CSS. Cascading Style Sheets is a language that manipulates markup languages like xHTML, or XML. I believe you will be suprised how simple CSS makes designing a layout that looks good and is also accessible compared to table-based layouts.
