Once that happens, you could use something that is somewhat CPU
intensive, but might be effective: steganography. Embed digital
watermarks in a few, select corporate image files (logos and such,
especially those in login screens) for each session (standard
cookie-based sessions can let you create the watermarked images and
cache them for the duration of the session or a timeout).

Then, when you find a copied image in a phishing kit, you get the
watermark, track down when/where it was downloaded (from your
watermarked files access log), and use that in your investigation of the
perp.

Just an idea, someone might be interested in working out its
feasibility.
