This story in today's FT magazine is interesting in its own right, but it makes a good security story as well:

1. Don't despise paper. Everyone quoted in the fake memos is dead, the empire they served is one with Nineveh and Tyre, and the record-keeping system was obviously not designed to detect this fraud, but the fakes can still be totally discredited. There is no shadow of a doubt that those notes are inauthentic, and the rest of the bundles they came from are real. What's the IT angle?
