I've spoken often before about the dangers of surrendering our privacy to pervasive monitoring and intrusive advertising by companies such as Facebook, Twitter, Google, and so on. I've also mentioned the risks posed by smartphone apps that demand to know your location, often for no discernible reason. Of course, they're selling your personal information to advertisers and other interested parties. However, most people appear not to care about that - something I still find inexplicable.
Karl Denninger warns that such lack of privacy may play into the hands of more than just predatory advertisers.
It wouldn't be hard at all to pervert "ad targeting" to collect a database of people who are extremely likely to be, say, military members.
Or their families.
Or virtually any other tightly-correlated group of people.
You can get very precise given the volume of data and tools today.
So you set up a company that allegedly wants to "advertise" to said people, you buy ads with that targeting and those who "click" or otherwise "interact" you now have pinpointed. In a short while you can correlate them through other sources and now you know who they are in real life, not just as numbers in a machine.
You know exactly where they work, where they live (down to the actual street address), where they worship (if they worship), where their children go to school and where they shop.
That little device in your teen's pocket, never mind yours, delivers your location on an exact basis, within tens of feet, 24x7 every single day.
The problem is that the bad guy isn't a company trying to sell laundry detergent or timeshares.
They're jihadists. Or Antifas. Or any other group -- or individual -- with motive and money -- and these days, not all that much money either. A few million is more than enough.
Still think all this tracking is no big deal, eh?
There's more at the link.
He's right, folks. This threat is real. My readers in law enforcement and the military, as well as other sensitive occupations, may want to take note, and make adjustments accordingly.
