There’s one going around right now. I get about 4-5 calls a day.
The caller identifies themselves as representing “Microsoft Technical Department”. They go on, saying they have observed suspicious activity in your account or some such.
If you continue, they have you enter a few strokes and a whole list of items pops up.(about 25) They say that each item represents someone, somewhere, who is currently using your computer for their own purposes without your permission.
They, of course, have a fix. Note, they do not ask for money.
Here’s the scam:
If you continue, they will lead you around Robin Hood’s Barn until they somehow retrieve private information about your finances, banks, credit cards, etc.
They sell this information to others, who eventually use the info to steal from you.
Play the numbers:
There are probably about a billion or more people in the US using a Microsoft Windows operating system.
Microsoft has a big enough “technical department” to monitor all of those people??? Not likely!
