Web browsers are used primarily for surfing the web; however, an outdated web browser can lead to the entire system being compromised. Clients may never use the preinstalled web browsers and instead choose one based on their preference; however, the default preinstalled web browser can still lead to various attacks on the system. Exploiting a browser by finding vulnerabilities in the browser components is known as browser-based exploitation.
