Tell your older relatives, don't share ANY information with people who call their phones.
Since all our SSNs are available to criminals, financial institutions are going to need other information to confirm who we are. Utility bill amounts/account numbers are a likely candidate, and the callers claiming to be offering solar energy installations lead by asking that.
I don’t even answer the phone.
And if the other person says “hello? Hello? Can you hear me?” Hang up!
@AlphaCentauri
Yup! Don’t say yes!
(Just hang up.)
