It seems there are some prolific technical support scammers ringing from 02085258899 pretending to be from BT. They had a very heavy Indian accent, and they have made many silent calls to my telephone number before today. They claim that hackers are accessing my router.
I wasted 37 minutes of their time, these are some of the steps to watch out for..
- They get you to open a command prompt and type ASSOC which brings up a big long list of file associations, in particular they seem interested in one that says .ZFSendToTarget=CLSID\{888DCA60-FC0A-11CF-8F0F-00C04FD7D062}
- Then they get you to bring up the Event Viewer by typing EVENTVWR and then clicking "Custom Views" and "Administrative Events". This is a log file that will always show a whole bunch of meaningless errors (such as network faults). It's quite normal for this to look quite bad to the untrained eye.
- Then in order they try to get you to connect to the following services to take remote control of your PC: www.anydesk.com, www.teamviewer.com and www.supremofree.com. All of these are legitimate services,but I have to confess I'd never heard of the last one.. so I will add it to my corporate blacklist.
- When those didn't work they tried directing me to a proxy at hide.me/proxy and www.hide.me/proxy (the same thing I know) which is probably another candidate for blocking.
