Isabella Di Fabio - What Is Javascript Injection And How It Works

Isabella Di Fabio Secret Story: The essence of JS Injection is to inject Javascript code that is executed on the client side. This method is probably the oldest method of Javascript injection, and it is the method we mainly use.

When a user enters a piece of Javascript code on your site, it is usually in the form of Javascript that is entered into the address bar itself. Line of Code Injection is a method used mainly in web applications such as websites, mobile applications and mobile apps.

When a text box or message appears, you can try to interrupt your website with the trickier JS injection method.

The most important thing is to know exactly which part of your site may be affected by Javascript injection and how to check it. To test this, you should have a general knowledge of Javascript and know which parts of the site are more vulnerable. Also, keep in mind that there is an input field in which you store some kind of data.

This is very important: any application that directly evaluates unvalidated input is vulnerable to code injections. Web applications are the main targets of attackers, so you should keep this code - injection techniques - in mind while you develop your web application to make it a more secure application.

Importantly, there are different types of Javascript injection attacks and none of them should be forgotten to test them. The nomenclature of code injection is complemented by the use of techniques based on JavaScript injections. 

You should always remember that JavaScript is one of the most widely used technologies in the world, but it is still a possible attack on your website. Since JavaScript was one of the most widely used technologies in the development of web applications, and since Javascript is the second and most widely used technology for web applications in general, you can be sure that it will be vulnerable to attacks.

Isabella Secret Story: However, if your application also allows you to insert JavaScript code, this would be much more interesting. Of course there are complications with this injection, for example, if JavaScript is disabled in Blink, the DidClearWindowObject event cannot be used to trigger the injection because it has been disabled. This would only disable the default scripts on the page, but it would work.

In principle, script injection is a way to respond to DOM loading in the browser engine by passing a set of JavaScript code to the JavaScript engine. To cope with this scenario, you can add scripts to your application and it acts as if they were part of the application. Injecting scripts must be as simple as a simple method of executing JavaScript code, not as complex and complex as injecting JavaScript.
