Caller: Supposedly Telstra

Asked me a question did i know About Hackers trying to get into my computer and laptop through my internet connection? I said Yeah.
She then said she will help me to stop them to do that. I said ok.
(I knew from the start it was a spammer but i wanted to see what they would say. )
When they asked me the same question above for the second time i said you just asked me that and she hung up.
