Either end, or at any point in between.  For instance, if I were bored
working the late shift on the service desk at your ISP, I might be tempted
to put a packet sniffer on the network backbone, just to satisfy my natural
curiosity :-)

Well, if I were bored and I did have a packet sniffer, the first thing I'd
do is to tell it to capture 10k blocks of data around the characters "user",
"pass", "login", "phone", "card", "id" - things of that nature.  I'd let the
computer do the really boring stuff whilst I read the juicy parts it found
for me.  Remember, I don't need to be on either end of this communication -
if your packets go from London to Brussels to Paris to Frankfurt, I can put
my sniffer at any of the nodes and see them.

Yours in thoughtful speculation,

Buck Calabro
