iFrame Overlay

Description

In an iFrame overlay attack the victim is tricked into unknowingly initiating some action in one system while interacting with the UI from seemingly completely different system.

Prerequisites

The victim is communicating with the target application via a web based UI and not a thick client. The victim's browser security policies allow iFrames. 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.

Mitigations

Configuration: Disable iFrames in the Web browser.

Operation: 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.

Operation: If using the Firefox browser, use the NoScript plug-in that will help forbid iFrames.

Skills Required

[High] Crafting the proper malicious site and luring the victim to this site is not a trivial task.
