This brought me to some thoughts about online banking security and secure authentication in general.
Today, most online banking goes through web interfaces. That's really horrible in the sense of security. I remember when I asked my local bank for an online banking account, they told me "hey, you just need a web browser to do this". They have better alternatives (HBCI), but they don't promote them to their normal customers.
With a web-interface, you only have a one-way-authentication (the user authentificates itself to the bank, but the bank doesn't) and that's the whole thing why phishing works. If there would be any mechanism that verifies the authenticy of the bank for the user (or, to be exact, his applications, because we all now that average users don't manage to do so), the whole phishing-stuff would be senseless.
Even the less secure variant of HBCI with keyfiles is much more secure than web-interfaces. For a successfull phishing-attack, a user would have to upload his keyfile - which he usually won't do, because he doesn't know where it is. But the most obvious way: Smartcards.
Smartcards can be a fine solution for various security problems - and it's not much more complex. Everyone knows that he has to put his bank card into a cash terminal, so why shouldn't the average user be able to put it in a computer slot? But hey, it's even hard to get smartcard-drives - I once asked in the Saturn (big german technology market), they don't sell them at all.
The right thing would be having smartcard-drives in computers by default - and having chipcards for various security-applications.
HBCI, for the ones who don't know, is a german standard for online banking - I wonder why there is no word-wide online-banking-standard yet - with a secure, open design and based on two-way-authentication, together with some easy-to-use standard applications for online banking installed on every PC. That would really help a lot.
