The chances of a malware author having a popular website with a high number of visitors are highly unlikely. So what the hackers do is that they place the malware into an existing legitimate site that has a lot of visitors.

Often times these malware injectors are website hackers. If not that they have the means of purchasing exploited websites from various services such as Hacking-as-a-service Service. They then station their malware on those websites.

2. Redirecting people to sites that do drive-by downloads

Drive-by downloads are the malicious activities performed by the downloading code, usually the JavaScript, on your browser without your consent.

The hackers design different malware for different devices. One the hacker identifies the device of the user it works on infecting it.

Examples of browser hijacking

In spite of the preventive measure at times the browser hijacking does occur. Here are some of the cases of browser hijacking:

1. Babylon toolbar

This toolbar came up in 2011. It was a form of adware which displayed ads in the search results and earned money from them. furthermore, it also collected the user’s data and gave it to the advertisers to make more money.

It was created by the CNET websites download.com without the knowledge of developers. The software changed the search engine to Babylon.com and slowly spread onto other browsers on the system.

2. Conduit

Conduit is one of the most abominable browser hijack available. It may seem innocent, but it changes every single of the default browser settings.

It is bundled software as it comes with many other download tools called the Conduit Search Projects. These tools although may seem harmless actually changes the default settings and then further locks out the administrator too.

This hijack works as adware as well as spyware. It displays pop up advertisements as well as collects confidential and personal data of the user.

This malware is particularly scary to deal with as it installs itself within the OS making it difficult for the user to boot it.

3. MyStart.IncrediBar Search

This browser hijack is by far one of the deadliest browser hijacks. Apart from working as adware and spyware it also works like a virus as well as a worm.

It uses the toolbar usually present in Firefox to redirect users towards MyStart websites. Mostly the website mystart.incredibar.com is used. This redirect minimally slows down the system and sucks up all the resources.

This hijacker is particularly nasty as it can’t be uninstalled. Once the user tries to uninstall it embeds itself further into the windows by making registry changes and installing new files.

The only way out is to completely clean the windows.

6 Steps To Prevent Browser Hijacking

If your web browser has ever been hijacked, then you must know the difficulty of dealing with its removal and resetting your browser, back to normal.

2. Google safe browsing

Google crafted this feature in 2006. This tool is continuously on the check of URLs. It primarily works to protect users from opening up a malicious website.

If a user opens up a link that happens to be malicious Google sends out a prompt. This prompt is a warning for the users to not open up the link as it is malicious.

3. Disabling JavaScript

You need to disable JavaScript in your browser. JavaScript can read typed stuff such as passwords, it can also find out relevant information like your IP address and can install other scripts without your consent.

Thus, it’s  better to remove by default JavaScript. Besides, you should use Script Block for Chrome and NoScript extension for Firefox to disable or enable it by the website.

4. Don’t Click that Suspicious Link

The software warns you whenever you are downloading attempts to change your browser settings. It may also offer you a chance to stop the changing of these settings. Adding a Second Opinion Scanner can work as a second line of defense with your anti-malware protection detail.
