Browser Hijackers – All You Need to Know

Have you ever opened your browser with the intentions of scrolling through your Facebook feed or checking out some videos on YouTube only to discover that your homepage is something entirely different from your new tab page and it seems to lead to all sorts of misclicks? Well, if you have, you’ve been a victim to a cyber malpractice known as “browser hijacking”.

It is more common than you think and believe it or not, effects more computers than you think. Sometimes, you may not even realize that the malware is installed – simply because you may not realize that your browser settings have been compromised.

Browser Hijacking is one of the most common form of malicious software. It gets access to your browser’s settings and modifies them without your consent and knowledge. There are several methods of doing this and the perpetrator is often motivated by monetary gain. It is extremely easy for a hacker to install a browser hijacking software on someone’s computer. They usually infiltrate your computer by sending spam mail or in some cases, include them as part of installation processes of other software that a user is trying to install.

There are times when all the hijacker does is change your homepage or browser opening page in order to direct traffic towards their website and earn money out of it, but this isn’t always the case.

For example, the browser hijacker CoolWebSearch changes your default search engine to theirs and a hacker using this hijacker can alter search results to direct your clicks to websites and information they want you to see. They can also track your searches and information and sell them to other websites for marketing purposes and monetary gain.

How do you know that you have been infected with a browser hijacker?

While it might be difficult at times to know whether your machine has been compromised, you need to look out for any abnormal behavior to determine if you have been a victim. Here are some of the things that you need to look out for.

– You might see that your searches are getting redirected to different websites that aren’t what you entered.

– Your homepage or search engine changed without you deliberately making any changes, and you are directed to a new page each time you open the browser.
– Webpages load slower than usual. (This could also be due to slow connection speeds, so if that’s the only issue check your speed first).
– You see multiple toolbars on your web browser at the top or the side – which you did not install. In fact, most of these toolbars may be malware that you do not need.

– You get multiple pop-up alerts for advertisements regardless of which web page you open up. Do note that some pages offer pop ups inherently and it would open through any browser so you need to know if it was happening before as well – perhaps login to a site you frequently visit.
