Block [email protected] phishing attempt in Office 365

A phishing attempt is spreading very quickly online. It is an email that looks very legit sharing a google doc. It usually comes from a trusted source since it is spreading via Gmail’s contact list. I even got hit with one at work. I wasn’t expecting any shared google docs so it raised my eyebrows and I did some quick searching online.

  1. Login to https://portal.office.com
  2. Admin Centers –> Exchange
  3. Mail Flow —> Rules
  4. + –> Create New Rule
  5. Apply the rule if the recipient is [email protected]
  6. Do the following: delete the message

I went a little further and add some more rules for extra insurance. I’m deleting anything from or to mailinator.com. My users have no need for that service. I also searched message trace for any other messages that came in so I could warn those users directly. Fortunately we only received one.
