Leak of the week: 711m email addresses

Written by: Lisa Forte

A French malware researcher has found an online database of 711 million email addresses, in some cases with the associated passwords for that account. The list was apparently for email spamming and is potentially the largest of its kind.


  1. You can check whether your email address is in this (or earlier) data leaks on at https://haveibeenpwned.com. If you find your account is on a list, log in and update the account to avoid it being compromised and potentially use for spamming activities or worse.
  2. Set up Two Factor Authentication (2FA) on your email accounts so that you need to give additional proof if you want to login to an email address.
  3. Consider deleting old email addresses that you no longer need them –especially if they don’t have an option for 2FA. Gmail, Outlook and Yahoo all support Two Factor Authentication.
