Part of the Malware glossary: An IFrame (Inline Frame) is an HTML document embedded inside another HTML document on a website. The IFrame HTML element is often used to insert content from another source, such as an advertisement, into a Web page. Although an IFrame behaves like an inline image, it can be configured with its own scrollbar independent of the surrounding page's scrollbar.
The document sending a message begins by obtaining a reference to the window it wants to send a message to. If sending a message to a document in an iframe, first get a reference to the iframe and then its contentWindow property as shown below. If sending a message from the iframed document to the containing document, the parent keyword provides a reference.
