Re: [WEB SECURITY] SSL does not = a secure website

If you look carefully about how it's implemented, it cannot help if a Trojan is onboard gathering the requisite login information, such as a BHO, DOM snooping, or a simple HTTPS proxy. If you enter "xyz123", the value submitted to the website is the same every time. This virtual keyboard implementation is not robust against anything but keylogging trojans. Therefore it's security theatre. As a Westpac customer, I find this frustrating as I have to use this "feature" in public places frequently, and I'm more concerned about shoulder surfing in those places.

An example Trojan which is close to breaking the new virtual keyboard:
http://www.symantec.com/avcenter/venc/data/pwsteal.bancos.q.html

These virtual keyboards violate accessibility requirements (which are required to be accessible by law here), and do not fix the primary issue - phishing.

There's little value in getting into any particular user's Internet Banking session. The value to the phisher is to conduct transactions, particularly to move funds out of the country. The only way to reduce the risk of that today is transaction signing. There are many different ways of doing this. As a Westpac customer, I'd prefer it they didn't spend good money on useless toys, but on real ways to reduce fraud and risk to me.
