What to do if Your Email is Hacked

  1. Change your email password (using something like 1Password to generate a random and unique password).
  2. Enable Two-Factor Authentication (2FA), also known as multi-Factor Authentication (MFA). See instructions further down on this page.
  3. Login to your webmail account and check for unusual settings...
    1. Email Rules (Inbox and sweep rules)
    2. Block or allow (Safe Sender and Recipients and Blocked Senders)
    3. Forwarding
  4. Notify the following people and explain what happened. This will help build security awareness and may prevent them from becoming the next target.
    • Co-workers.
    • Everyone in your address book. You must assume your address book has been stolen, even if no email appears to have been sent from your account. If you don't use an address book then consider your Recent (or Previous) addresses as stolen.
    • Client and vendors, if appropriate.
