So you have been conned into sending money to the wrong bank account.  

It's easier than you think. You receive an email from your accountant asking for payment. What you don't realise is that your accountants' email has been hacked.  

The Banks, backed up by the FCA, are washing their hands of all liability for this type of fraud.  

But are they right to do so? 

On the face of it, you may think so but this article makes some contrary arguments that are worth noting.  

My point all along is this: banks cannot afford the bad PR that is the truth of it - they need to forget about the technical arguments as to where blame should lie, and look at the bigger picture. Sooner the better.
