How does saying "hello" give scammers your details such as your name?
Pragmatically, even basic words from your voice can be used to estimate your age, gender, and geographic region (local accents).
But also read other comments, people are saying they answer their phone by stating their name, so plenty clearly use it as a greeting.
Even if I am expecting a call from a service provider, insurance, bank, whatever…
They’ll want you to identify yourself, name, dob, address.
Never do this to unverified inbound callers.
And how do you verify an inbound caller is who thru claim they are and not a scammer?
You don’t. You tell them you never give out PII to inbound callers as they are indistinguishable from scammers.
Then call the them on their publicly listed number and deal with the issue from there.
We need to encourage service providers to stop doing that as it is exactly leads to people being more easily scammed.
Not sure what system they're using, or why there's that characteristic BLOOP.
