The smell test
A million victims a day?
Okay, there are, give or take, 7 billion people in the world. Let's suppose half of these have Internet access. Then your chance of being scammed online, per year, is (365/3500 = about 10.5%).
So in the past five years, almost 50% of the people around you should have been victims of "cybercrime". Does that sound plausible?
Well, maybe if you stretch the definition a bit. If marginally misrepresenting something on eBay counts as "cybercrime", or if visiting a website that's been defaced by vandals makes you a "victim", then I could maybe believe that statistic. So what will Norton sell me to protect me from these outrages?
Yeah, right.
