What is Privilege Escalation

Browser attacks over the years have stormed the Internet world with so many malicious activities. They provide unauthorized access and damage or disrupt user information within or outside the browser. This chapter focuses on the complete attack actions adopted by an attacker while crafting an attack on Web browser. The knowledge gained from the attacker's actions can be framed into a suitable taxonomy, which can then be used as a framework for examining the browser attack footprints, vulnerability in browser design, and helps one to understand the characteristics and nature of an attacker. This chapter presents a browser attack taxonomy that helps in combating new browser attacks and improving browser security.
