HTTP: Malicious JavaScript Appended to Existing JavaScript

This signature detects a malicious JavaScript that has been appended to an existing non-malicious JavaScript. This technique is where an attacker will compromise a normally benign website and adds malicious content without the site's owner being aware of it. A successful attack would result in a complete compromise of the viewing user's browser.
