As a mail system administrator for several domains, I witness the never-ending onslaught of spam, scams, and phishing attempts. It is absolutely relentless. Scammers are constantly coming up with new social engineering techniques to illicit a response, or new topics that they know many people will fall for. They often target specific individuals, and can exhibit considerable insight with regard to staff members' roles and even their current projects. I suppose this should be no surprise given the extent to which devices like computers, smartphones, and the Internet itself have evolved into a vast network of surveillance tools, vacuuming up data on everything we do. One thing is for sure - it must be effective, because the scams never diminish, they just keep coming and coming. Right now I'm seeing about 25% of all emails are scams. And that's only the ones that are getting blocked.
