Quick definition: Browser hijacking is a type of cyberattack where malicious software modifies a web browser’s settings without a user’s permission. It typically redirects users to unwanted websites, changes their homepage, or displays intrusive advertisements.
Explanation
Browser Hijacking is a form of malicious software or unwanted program that alters a web browser’s settings without a user’s permission. It typically works by injecting code or installing extensions that change the default homepage, search engine, or error pages to those controlled by the hijacker. This is often done to generate advertising revenue through forced clicks or to redirect traffic to specific websites, which may contain further malware or phishing scams.
A common misconception is that browser hijacking is merely an annoyance or a side effect of a slow computer. In reality, it is a significant security risk that can lead to data theft, as hijackers may track browsing habits or capture sensitive login information. Another myth is that simply closing the browser or restarting the computer will resolve the issue. Because the hijacking often involves persistent software installed on the system, it usually requires specialized security tools or a manual reset of browser configurations to fully eliminate the threat and restore privacy.
