Our old monitor seems to be on its last legs, so I've just been to Scan's website (from where, >10 years ago, the now dieing monitor was bought) to replace it. Found one I liked, then tried to pay for it. Unfortunately, like most online merchants, they've been bullied into implementing 3D secure (aka Verified by Visa/MasterCard SecureCode).
Oh how I laughed when NoScript popped up a warning saying that it just blocked a XSS attack from www.securesuite.co.uk (which was trying to POST back to www.scan.co.uk).</sarcasm>
So, not only does the user experience to all intents and purposes look exactly like a phishing attempt, a successful payment gets blocked by security software. Thus, in order for 3D to work (remember this protocol is designed to make the purchasing on the web "more secure"), I have to make my PC less secure?!?
Anyone would think this had been designed by a government.</despair>
