Code injection: the uses

Web
code injection

There is little talk of code injection.
Or rather, it is little talked about among the non-professionals, because this technique is very common and used.
Commonly used by anyone even without knowing it.

The time has therefore come to deepen the discussion and understand what it is.

Code injection: meaning

First of all, let’s analyze the term code injection and let’s see the meaning:

Code injection is used by applications and software of all kinds to “inject” lines of code into another software, in order to influence its operation. Code injection is also called DLL injection (from Dynamic Link Library files, usually used to manage system processes in Windows), since in most cases the code to be injected into a software is in the form of dynamic system libraries.

Let’s focus on safety

One of the most important aspects to keep in mind when talking about code injection is the security issue.

In fact it is one of the most common techniques used by hackers to “enter” computer and software systems and steal sensitive data and / or confidential information.

Other uses

But we must not think that the code injection technique only creates problems: there are many other legitimate and beneficial uses.

For example, we must absolutely name antiviruses that use this method to evaluate whether a website or file is safe or not.
And then we must also mention the drivers of the video cards.
In short, the “good” uses are many.

How to find out if you are using code injection

If you are now wondering whether your softwares are using a code injection technique, well, you can find the answer using a specific tool.

In fact,  Microsoft comes to our aid by providing a free tool called Process explorer whose purpose is to monitor the active processes in the PC and their operation.
