Below is a copy of a post I made on face book earlier today, this actually happened to me:-
I've just had a rather interesting telephone conversation. The call was from someone calling themselves "Martin" and was calling on behalf of the "Technical Department of Windows". Anyone smell a scam here?
Anyway, being the kind person I am I thought I'd waste his time. According to him they had discovered that my computer had be compromised and was being used as a botnet. Playing at being gullible and stupid I asked him what a botnet was?
After he explained what one was I fed him the line "How do I fix it?". To fix would cost me £200 and he needed My email address, password, name and address. So I gave him a load fake info. Then he asked what my occupation was. My reply?
"I'm an IT Security Consultant"
Funnily enough at this point he put the down. I wonder why?
