It is more likely to be the likes of you and me that get hit .......... if Fossen is right. As you say - it is just speculation.
How many people keep important details ( bank details for instance ) on their computers?
Millions upon millions I suspect - worldwide.
$50,000 is not a lot if you are guaranteed access to these sensitive details.
Do phishing emails get sent to banks and multi-nationals?
It is joe public they target because they know we are basically stupid ( generalisation :) )
Also - I doubt that banks and multi-nationals would still be using XP. They would have upgraded years ago.
And if they are still with XP then I suspect that they would upgrade before MS support is totally withdrawn.
No, if there is going to be anybody targeted it is going to be the general public.
There is another angle to this too.
Micro$oft would be only too happy to see a "zero day" exploited. They would come back with an offer to XP users to upgrade. :)
Not so stupid are they ?
Watch this space.
