Is there a specific universal sms exploit I am unaware of? Do you need to know the OS running on the phone or the specific version for a given exploit?

Is this only affecting smartphones?

You see where I am going with this.

Also, It’s getting pretty hard to buy an analogue cordless phone these days. You’d need a lot more than a VHF scanner to monitor the conversation on any modern digital cordless phone.

There is a lot of mixed in with some valid information here along with a laughable we must license and control the internet conclusion from your ‘expert’.

I’d prefer a bit more research and analysis and a bit less advertising for some blokes detective agency.
