I would never use online banking, and I advise all my friends and
colleagues (particularly those who _aren't_ computer-security-geeks)
to avoid it.

Ahh, but how do you know that the transaction actually sent to the
bank is the same as the one you thought you authorized with that OTP?
If your computer (or web browser) has been cracked, you can't trust
_anything_ it displays.  There are already viruses "in the wild"
attacking German online banking this way:

I also don't trust RSAsafe or other such "2-factor authentication"
gadgets, for the same reason.

[I don't particularly trust buying things online with a credit card,
either, but there my liability is limited to 50 Euros or so, and the
credit card companies actually put a modicum of effort into watching
for suspicious transactions, so I'm willing to buy (a few) things online.]

ciao,
