Software Update Scam
Caller identified as singtel stating that my internet has been compromised by an overseas IP Address.
She asked several questions about my network which I refused to answer and instead asked for the IP address that compromised my network.
She stated that i need to open a browser on my computer and she will show me. I then asked if she at least can tell me my public ip address. She replied that i need to open a browser as she doesn't have access to a computer right now.
I then said that I'm a system administrator and i know my network very well.
She then hung up.
