Caller: Telstra scammers

Claimed they were from Telstra home internet (which we have never had) and that someone was using our connection illegally. They wanted to find out what devices are connected to our network. I told her that this was a really obvious scam and she hung up immediately. No doubt if she'd been allowed to continue, she would've wanted me to allow her remote access to my computer, she'd "discover" "Trojans" that hackers are using to access my computer (either legitimate running processes in task manager or innocuous entries in event viewer) and then sell me a fake antivirus to stop "hackers" illegally using the Telstra internet I don't actually have.
