Concept
XSS worms exploit a security vulnerability known as cross site scripting (or XSS for short) within a website, infecting users in a variety of ways depending on the vulnerability. Such site features as profiles and chat systems can be affected by XSS worms when implemented improperly or without regard to security. Often, these worms are specific to a single web site, spreading quickly by exploiting specific vulnerabilities.
Cross-site scripting vulnerabilities are commonly exploited in the form of worms on popular social or commercial websites, such as MySpace, Yahoo!, Orkut, Justin.tv, Facebook and Twitter. These worms can be used for malicious intent, giving an attacker the basis to steal personal information provided to the web site, such as passwords or credit card numbers.

“To find the length of an object, we have to perform certain
physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.”
—Percy W. Bridgman (1882–1961)
