Protect Yourself From Browser Hijacking: Understanding the Threat and Taking Precautions

Browser hijacking is a type of cyber attack that targets internet browsers, altering their settings without the user’s permission. The hijacker takes control of the browser, forcing it to perform actions that the user does not intend to perform. These actions can include redirecting the user to a different website, displaying unwanted pop-up ads, or even installing malware on the user’s computer.

In this article, we will discuss the types of browser hijacking, the techniques used by hijackers, and how to protect yourself from this type of cyber attack.
