I received a call from +65 97112189. An Indian lady was on the line claiming that she’s calling from singtel as they observed that there has been more than 20 users connected to my WIFI. She confirmed if she was speaking to the account holder, if we have been facing WIFI issues (which we indeed Have), if we have good password practices, the number of devices we have connected to our wifi. The first time i questioned her identity, she responded that she has been authorised by singtel to follow up with customers with this issue. She then requested for me to use a laptop and follow her instructions to reveal the ip addresses of the unauthorised users. that is when i questioned her identity a second time, given that there was no call from singtel prior to this call and that she was calling from a private mobile number.
She then hung up immediately.
