Definition[edit | edit source]

Content injection attack refers to inserting malicious content into a legitimate site.

Overview[edit | edit source]

In addition to deceptive actions such as redirecting to other sites, malicious content can install crimeware on a user’s computer through a web browser vulnerability or by social engineering, such as asking a user to download and install anti-virus software that actually contains crimeware.

There are three primary classes of content injection attacks, each of which has many possible variations:

Cross-site scripting and SQL injection are propagated through two different primary vectors. In one vector, malicious content is injected into data stored on a legitimate web server, which a victim is exposed to. In the other vector, malicious content is embedded into a URL that the user visits when he or she clicks on a link. This is commonly a URL that includes components that will be displayed on screen or used as part of a database query, such as an argument to a search function.
