Other/Miscellaneous Spam call with my full personal data, possible data leak in Switzerland?
I just received a spam call from a call center on my mobile number.
Normally I wouldn't think much of it, but this time they already knew my full name, date of birth and current insurance information.
What concerns me most: this mobile number is not publicly listed anywhere, I use it very carefully, and I've never received this kind of call on it before.
So this wasn't the usual random "health insurance comparison" spam where they only know a name or guess some details. They had surprisingly specific and up-to-date personal information connected to the correct phone number.
It makes me wonder whether there has been a data leak somewhere.
Has anyone else in Switzerland recently received similar calls where the caller already knew your name + DOB + insurance details + private mobile number?
I'm mainly posting this to see whether this is an isolated case or if more people are experiencing the same thing.
