What Is A DLL Injector?
You have probably heard the term DLL injector mentioned before. Ultimately, you are talking about something that is commonly utilized by two different camps. If you are a gamer, or if you have a vested interest in malware-based security, you may want to study the concept of a DLL injection in greater detail.
Furthermore, in order to appreciate a true DLL injector definition, you will certainly want to take a look at some examples of DLL injection.
Defining DLL Injector
You will find this injector being used by external programs in computer programming. DLL injections are going to involve inserting code into running processes. The aim of these external programs is going to be to influence the behavior of other programs. The ideal end game is to influence the program to do something that the designers of that program never intended or accounted for.
These techniques are going to run code within the address spaces of other processes. The injector will now force the process to work with what is known as a Dynamic Link Library. This is where the whole concept of DLL injector becomes clear.
The code that is usually being inserted will come in the form of a DLL. This is because DLLs are designed to be loaded as needed during run time. Even so, this doesn’t translate to being able to inject assembly into any other forms. Furthermore, you should keep in mind that in order to mess around with the memory of a program, you are going to need certain privileges within the system.
A good example would be a scenario in which injected code can be used to hook any system function call you can possibly imagine. Another good example would involve someone using this code to peruse the contents the contents of a password textbox. Remember that these cannot be undone in the standard fashion.
More often than not, when we talk about a DLL injector, we are talking about something that was created by a third-party developer for malicious purposes. Since these injectors are designed to force a program to do something it doesn’t want to do, there is a considerable risk factor that is extended towards your computer or other device. While we do not know where DLL injectors originally came from, we do know they come in a variety of forms. Beginning with Windows Vista, Microsoft tried to address the problem by introducing what is known as the protected process.
