In a recent advisary notice, Ofcom has warned the general public not to trust Caller ID as a way of knowing or identifing who is calling you.
Caller ID is like a global contacts list. You probably have a parent or sibling saved in your phone so that when they call you don't just see the phone number, but thier name shows on the screen. Caller ID does this for many major companies that register the number as a way of the end caller knowing who is calling them.
Recently however, this has been abused by scammers to make the end caller think someone such as there bank is trying to contact them when in reality its a scammer.
Number Spoofing is becoming more and more of a problem as telecoms companies deal with older infrastucter and the inability to differentiate between the real companies calling customers and someone pretending to be that company.
DNDW will be doing a deep dive into how spoofing numbers is possible, and why it's so hard to stop in the future.
It's estimated that in the UK alone, 40,000 people last year where unfortunately tricked into losing some amount of money from calls related to Caller ID fraud being used to convience them it was a legitiate call.
If your bank calls you asking you to pay a fee or transfer money, or just in general if your bank is calling you seemingly out of no where. DO NOT provide any infomation or payment over the phone!
You can always hang up and call them yourself.
