46. Do be aware...their are aggregators that get personal data from all your connections and build a profile of YOU.

While entities like banks and a few others may be fairly secure, most retail, hospitality and open source systems are just a 10 minute hack away from letting all the info go to whoever. Most have been hacked and are so ignorant or just focused on profit that they don't pay attention. My wife works in cybersecurity and a few years ago did a study of a major utility district in the Western US. They controlled several hydroelectric dams and the concern was could a bad actor get in and get control of the dams to extort money or as a terrorist act release all the water to flood downstream and stop power generation. The answer was yes and there were already fingerprints from the likes of Iran, North Korea and others that they found ways in. While the focus was on control of the dams, the study noted that personal data around employees and utility customers was also accessed. The study could not tell if data was copied but if you are right there, even if your intent was other, why not vacuum up the low hanging data fruit that maybe you could sell to someone to help fund your ongoing nefarious operations? As a result of this my wife and I stay off most social media and use false names and burner phone numbers and dead end emails wherever possible for other on line tasks so that aggregators get noting but unlinkable dead info.
