Spoofing is a deceptive practice where an attacker disguises their identity or the source of a communication to appear as a trusted entity, often to gain access to sensitive information, steal money, or spread malware. It involves impersonating someone or something else to mislead victims and gain their trust. This can happen through various channels like email, phone calls, and even network protocols.
The most common is calls from someone pretending to be your bank. Thanks to Martin Lewis, I found out about the 159 service. If you suspect that you are the victim of spoofing and you want to call your bank to check, you can use the 159 service. Simply dial 159 from a handset when you’re in the UK and the service asks which bank you want to speak to. You can read more here: https://stopscamsuk.org.uk/our-work/159-phone-number/
Crucially, 159 will never call you, so if you receive a call from 159, it won’t be someone from your bank.
