- The victim uses a modern browser that supports UI elements like clickable buttons (i.e. not using an old text only browser)
- The victim has an active session with the target system.

Mitigations
- If using the Firefox browser, use the NoScript plug-in that will help forbid iFrames.
- Turn off JavaScript, Flash and disable CSS.
- When maintaining an authenticated session with a privileged target system, do not use the same browser to navigate to unfamiliar sites to perform other activities. Finish working with the target system and logout first before proceeding to other tasks.
