Ping!
As computer costs keep dropping, would it not make sense for ‘whales’ to have two completely separate machines, one for e-mail/internet and one for other business functions. I know that would make some operations awkward, but it would be far more secure...
This stuff is coming for everyone, eventually. In the old days, you needed a good fence, a sturdy door, and a solid lock - and a shotgun, too, for those extreme emergencies. I suspect that this kind of software will be waiting to target anyone for anything - employee vs employee, with one looking for info to the other fired; employer vs employee, looking for violations, either real or planted by the software itself; employee vs employer, ditto.
For me, it starts with what I post at sites like this. Sure, I have a psuedonym, which I believe to be totally insecure. Anyone can find out who I am if they try hard enough. So I make sure what I write can’t be used against me. I’m also very circumspect about what I do online, too - which isn’t hard if you lead a life which is based on Christian values, although I’ve fallen off the wagon a few times. In any case, that doesn’t prevent fraud or deciet with my name on it. I have firewalls with firewalls; backed up data outside the grid; and I can see where someday we’ll have to have our own software watchdogs looking for trouble. *sigh*
