Malicious Browser Extensions: The Hidden Threat to Your Online Security

In recent years, the world of cybersecurity has witnessed a significant rise in malicious browser extensions that have infected millions of devices worldwide. These extensions, which are designed to enhance our browsing experience, have been exploited by hackers to steal sensitive information and compromise our online security. In this article, we will delve into the world of malicious browser extensions, exploring how they work, how to identify them, and most importantly, how to protect ourselves from these threats.

The Rise of Malicious Browser Extensions

According to a report by cybersecurity company ReasonLabs, over 300,000 users of Google Chrome and Microsoft Edge have fallen victim to malicious browser extensions since 2021. These extensions, which are often disguised as legitimate tools, can steal sensitive data, including passwords, financial information, and browsing history. What makes these extensions even more dangerous is that even if users delete them, the malware stays on the computer and will activate every time the system is turned on.

How to Know if Your PC is Infected with Malware

If you are infected, you will be frequently redirected to the hacker’s search portal irrespective of the fact that you have Bing or Google as your search engine. Furthermore, you can check the files in the system folder to check whether you are infected with malware.

How Hackers are Attacking Computers

Just like other malware campaigns, this also uses malvertising (malware + advertising) to trick unsuspecting users into downloading and installing risky software. For example, when you search for any tool – let’s say convert word files into pdf – there may be an advertisement of a browser extension that says users can convert as many files as they can with the extension.
