Batchography: Batch files and Unicode

Recently, I had to update my popular utility that resets NTFS files permission to support Unicode paths. I had to investigate how to add Unicode support in Batch scripts. It seems that this was a topic I forgot to add into my comprehensive Batch files programming book.

This article is the result of my investigation, in which I am going to show you how to add Unicode support to your Batch file scripts in 3 easy steps.

Batchography: Embedding Python scripts in your Batch file script

I keep writing about Batch programming, so it is obvious by now that Batch files programming has become one of my favorite activities. Every time I have to write a quick script to automate a task, I go first for the Batch files programming language. If that does not do the job, I use the Python programming language and if that fails, I go for C/C++ before deciding to writing using the assembly language.

Now, what about combining the two languages to achieve what you want?

That’s today’s topic. It is an excerpt from Chapter 4 in the Batchography book. Continue reading

7 DLL injection techniques in Microsoft Windows

In this article, I am going to list half a dozen DLL injection techniques that can be used by a user mode process running on MS Windows. There could be more techniques but I am sharing with you the techniques that I had first hand experience with.

1. AppInit_DLLs

People used to rely on the AppInit_DLLs registry key. The OS loader queries this value and loads the DLLs specified there when a process is created. I have not used this technique in a long while (last time I used it was on Windows XP) and I heard it is now restricted or discontinued because it was widely used by malware.

2. SetWindowsHookEx API

The SetWindowsHookEx API installs an application-defined hook procedure into a given hook chain. There are various supported hook chains (CBT, Journal, Window messages, keyboard, mouse, etc).

When using the SetWindowsHookEx API, you are instructing the operating system to inject your custom hook DLL into other process where it is relevant. The Windows hooks work when the other processes import / use functionality from USER32.dll.
