[eOutage] Proofpoint did not scan email attachments with Attachment Defense

[UW Information Technology's email notification service regarding widespread outages]

    UW-IT engineers identified that our Email Security vendor, Proofpoint,
   experienced issues with the security feature called Attachment Defense.
   This allowed some emails to be delivered without scanning attachments.
   .
   This incident has been resolved by Proofpoint.
   .
   Extra caution should be taken when opening attachments that were
   received on 1/17/24 between 6:30 am and 11:00 am. Please be careful
   opening any attachments to emails from unknown sources and extra
   caution should always be used when opening attachments in email at all
   times. For more information about this visit:
