Are you aware of what ‘spoofing’ is?
‘Number spoofing’, works by fraudsters cloning the telephone number of the organisation they want to impersonate and then make it appear on the victim’s caller ID display when they telephone them on a landline. Spoofed messages can even appear in the same message stream as previous legitimate messages!
