Technical Details

Obfuscated JavaScript may be found embedded in HTML pages, or contained in iframes hosted on those pages.

Visitors to these sites may then be subjected to the payload of the obfuscated script, which can range from redirecting to the user to an unsolicited and/or malicious site to silent download and execution of files onto the user's machine.

When delivered via malicious advetisements (typically provided by third-party marketing services in good faith, and displayed on legitimate websites), this is a form of malvertising.
