A series of banks may leave customers vulnerable to fraudulent spoofing attemps - including HSBC, Lloyds Banks, Santander, TSB, Nationwide Building Society, and Virgin Money.
An investigation at Which? examined how effective banks were at protecting their customers against fraudsters who impersonate legitimate customers in order to deceive victims. These scammers often forge the name or number that appears on an email, phone call, or text so that it appears to be genuine.
However, companies can sign up to regulator Ofcom's Do Not Originate (DNO) list - a shared resource with telecom providers that help identify and block calls that are likely spoofed - to make it harder for fraudsters to impersonate them, the Liverpool Echo reports.
