Nusuni Frame Buster is a quick’n'dirty plugin that will make your WordPress site either break out of all frames, or only specified ones. The plugin is released as opened source under the Modified BSD license.
I have tested the plugin under the latest WordPress release, but it should work fine on any WP 3.0 and above releases. If you encounter any bugs, feel free to let me know.
