800M Email Addresses Leaked Online by Email Verification Service
I strongly believe that we should be keeping our email addresses as secure as our passwords. It’s a really important attack vector as it’s often the starting point for any targeted attack, and although it’s not usually considered as a factor, it is the 2nd factor required for most logins (email and password). Triggering important security processes (eg reset password, social engineering attacks) are trivial once you know someone’s email address.It’s clear from this hack that the owners of the hacked site didn’t see emails as something worth securing (stored in plain text on a wide open mongo server)If you want to keep your email address private (you should), generate a new, random email address whenever you give yours out (the same way you use a password manager). If you have your own domain you can use a catch all/wildcard address, eg. *@mydomain.com, if you use gmail you can use their plus support, e.g. John+uniqueidentifier@gmail.com, if you use neither or want more security I’ve recently launched https://idbloc.co which aims to help deal with this.
