Read an article about Dark Web written by Doug Schadel and Neil Wertheimer, published in AARP Bulletin September 2018, pages 10 to 18.
I have been paying attention to what is written and said about Cybersecurity and Infosec. I learned best practices from years of doing research work that included keeping integrity, privacy, safety and security of data. I went to DEFCON this year. I enjoyed reading this article. The article clearly explains what things are and how they work. Like TOR, who developed it and that it stands for Onion Router. The authors do a good job of explaining what of your information is being bought and sold ,something called fullz profiles. The article concludes with the advice of freezing your credit, closely monitor all accounts and using a password manager. Follow this good advice.
