Scammer called to say he is from Singtel technical dept., and my home internet was hacked. Then wanted me to get in front of computer to "rectify and block" the supposed hacker. He would talk me through the sequence on how to proceed. Of course I didn't do this. When I start asking questions he couldn't answer and after asking him to identify my IP address and details of my internet subscription etc. he hung up.

No damage done. Just wanted to alert you.
