For the past few weeks, I have been receiving silent calls every day from the same fake number – 01001246. When I pick up, the other end is either silent, or a dial-tone. I have reported it, but was told nothing could be done because the caller-id was spoofed. Well duh – I wonder if the NSA and GCHQ are equally stumped by fake numbers?
Anyway, today’s call came through during my tea break, and this time there was a person on the other end, telling me that he was calling about the security of my Windows machine. “Oh, that one”, I thought; but didn’t hang up, as I was curious how these guys go about “proving” a machine is infected.
