I'd dispute whether 'reported' figures are massaged significantly by the banking industry to be honest, if only because I fail to see how they would benefit by doing so. They appear, after all, to be happy to make it clear that they consider most of the liability to fall with the customer.
If phishing does make up a significant proportion of bank fraud, I suspect that the answer is rather more simple - customers have simply become more wary of phishing attacks. Contrary to the sort of opinions often posted on here, non-technical users of facilities like internet banking are not thick. They are however often not aware of the risks.
Non-targetted phishing was bound to suffer from the law of diminishing returns and even the dimmest of internet banking customers will become more wary if:
- They receive repeated emails claiming to be from banks that they dont
even bank with
- These emails are often written in poor and ungrammatical English
- They receive periodic reminders when they logon to their (legitimate)
bank's online service reinforcing the fact that your bank will never ask for
certain details. My own bank, Smile, have been very dilligent.
You genuinely cant fool all the people all the time. At least not for very long......
