Situation guides: what to do about the suspicious
Step-by-step guides from the NoCall team for acting in each suspicious situation.
A call from a relative in trouble with an AI-cloned voice: how to verify
You hear your son, your granddaughter or your partner: they've had an accident or been arrested and need money right now. It may be a voice cloned with artificial intelligence. Here's how to check in a couple of minutes and what to do.
Selling on Wallapop or Vinted and the "buyer" asks for my details or sends me a link
You list something for sale and a so-called buyer sends you a link to "receive the payment" or "arrange shipping", or asks for your card details. It's a scam aimed at sellers. We explain how it works, how to spot it and what to do if you've already fallen for it.
"You've won a prize": the fake raffle by call or SMS that asks you to pay
You get a call or an SMS: you've won a raffle, a phone or a gift card, and all that's left is to pay a small fee or give your card details to receive it. It's a scam. We explain how to spot it and what to do if you've already shared your details.
Job offer on WhatsApp or Telegram: the "task" scam
A stranger offers you easy money from home for liking videos, following accounts or writing reviews. At first they pay you, then they ask for deposits. Here is how it works and what to do.
Fake traffic fine by SMS: what to do and how to check if it's real
You get a text from the traffic authority about an unpaid fine, with a link to pay it at a discount before the deadline. It's smishing. We explain how to spot it, how to check whether you really have a fine and what to do if you already paid.
"I sent you a code by mistake": how your WhatsApp gets stolen
A contact or a stranger asks you to forward a 6-digit code you just received by SMS. It's the WhatsApp and Telegram account takeover scam. We explain how it works, what to do if you already sent it and how to lock down your account.
A foreign number is calling me: what to do and how to block it
You get a call with another country's dialling code and you're not expecting anything from abroad. We explain the real risks, why you should never call back, what to do if you already answered or returned the call, and how to block these calls.
"The police" or "a court" is calling me: the fake officer scam
A voice claiming to be a police officer, prosecutor or court official tells you you are under investigation and demands payment or your details. It's a scam. We explain how to recognise it and what to do.
"Can you hear me?": the call that tries to record you saying "yes"
You pick up, a voice asks "can you hear me?" or "are you the account holder?" and the line goes dead. Can a recorded "yes" be used to sign you up for something? We separate myth from reality and explain how to respond.
"Hi Mum, I've got a new number": what to do if your "child" asks for money on WhatsApp
An unknown number messages you on WhatsApp claiming to be your son or daughter, with a new phone and an urgent transfer to make. Here's how to check it in a minute, what to do if you've already paid, and how to report it.
Fake Microsoft technician: they call because your computer "has a virus"
Someone from "Microsoft", "Apple" or your antivirus calls: your computer is infected and they want you to install AnyDesk or TeamViewer to fix it. It's a scam. We explain how to spot it and what to do if you already gave them access.
Fake debt collectors: threatening calls about a debt you don't owe
Someone calls demanding immediate payment of a debt you don't recognise and threatens a lawsuit, seizure of your assets or even arrest. We explain how the scam works, your rights and how to check whether the debt is real.
