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.
The target system's interaction window is open in the victim's browser and supports the ability for initiating sensitive actions on behalf of the user in the target system

Competenze richieste

Crafting the proper malicious site and luring the victim to this site are not trivial tasks.

Risorse richieste

None: No specialized resources are required to execute this type of attack.

Mitigazioni

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.
