Information Leakage

So I was recently pointed to Meng's blog (by both Rourke and Meng), and noted this recent entry. Now, okay, you gotta subtract out the whole creepy-stalking-girls premise and replace the guaranteed-everyone-blogs assumption with something more probabilistic. (I was somehow in the mood to ponder this stuff after randomly watching the last episode of this BBC spy-reality-tv show that was actually quite engrossing.) What's left is a pretty interesting almost-anonymous information leakage attack that can be executed against live people in a non-electronic context with some probability of success.

I guess I find it interesting because, as someone who blogs fairly often, I can see myself falling for this kind of attack without realizing it. If I were a a diary type blogger, I could probably fall for such an attack even more easily. This tagging attack strikes me as one of those things that's ingeniously devious from one perspective, while completely invisible from another. But now, I shall be on my guard...
