Telstra gave me a cold call, from (+61379800654 ; Australian number) and stated that hackers are accessing my computer. So then I was passed onto a Supervisor who called himself “Daniel Boyd” from the Anti-Hacker Department of Telstra. I basically needed to renew my gateway for $5.99 (AUD). He asked what I did on my computer and I said Internet Banking and YouTube. Where he got so excited and won the lottery (type of emotion) when I stated that. He wanted me to log into the following:
www.netbank.com.au
www.telstra.com.au
He told me to go too:
www.validator.w3.org
(or something similar to this)
His Teamviewer account number is 757081823 and password 123456.
I then disconnected him from my internet connection and he went crazy. He claimed to have put a "syskey" on my computer and he didn't remember the random number. Unfortunately, by that stage I was in the middle of a reboot and he didn't add a syskey.
