Other than sliding content over the top of the IFRAME, there are fun ways to
get exactly the appearance the attacker wants ... keep in mind when
designing a solution:
-- make the IFRAME opacity:0 (or 0.01) and draw whatever you want underneath
-- use SVG <filter> effects (in conjunction with SVG <foreignObject>, or CSS
extensions to apply filters to non-SVG content) to simply replace the
rendering of the IFRAME with something else.

"He was pierced for our transgressions, he was crushed for our iniquities;

own way; and the LORD has laid on him the iniquity of us all." [Isaiah
