Troy Hunt, the renowned Australian information protection specialist and creator of Have I Been Pwned (HIBP), an internet resource to help you understand if you have been the victim of stealing one of your online registrations, alerts you to the huge amount of data on the web For an entry that is located on an open web server.
And while your email may not be present in the huge HIBP base, never forget a few simple tips on using your email. Avoid signing up for postal services that do not provide a secure connection between you and the server that stores your data. Use a complicated, hard to guess password or a secret phrase that you can remember (such as k0Lk0p0zleM0zed @ sTane ?!) or password manager. Do not use the password or secret phrase on other sign-up sites. Do not use your official email to sign up where you drop, but rather make a special sign up for it. If available, include an additional authorization feature. And, of course, show good sense and healthy suspicion in your online quests.
