There has apparently been discovered a vulnerability in the TCP protocol. (SlashDot readers will know this fairly soon if they don't already. ;) )

This could get ugly. (Could this get ugly?)

I thought guessing sequence numbers was an old thing?

If that's the same thing I recently read, it can be done without guessing sequence numbers. All you need to know is the source/dest port/ip.

I don't think so, from what I've seen you rarely know the necessary ports, and even if you do most connections could be remade anyway. I don't see this being much of a problem.

Ah well. It's newsworthy, anyways. =)
