CUIT apologizes for any inconvenience this may cause, but this action is necessary to ensure a more reliable service. If clients continue to experience issues after the service-interruption hours, please contact the CUIT Helpdesk at:
UPDATE 3/11/2015: The spam activity continues to a lesser degree (497 sent here on 3/10), but since the columbia.edu filters are successfully stopping the mail there is no further problem on CUIT systems.
UPDATE 3/9/2105: The spam activity from CUMC stopped dead over the weekend but resumed Monday morning. 3,400 were sent to columbia.edu in the first 45 minutes, and rejected. As before CUMC is successfully removing the bad zip file attachment, but sending out the altered message.
UPDATE 3/6/2015: 15,000 similar spam messages from cumc.columbia.edu to columbia.edu were rejected today.
Yesterday, many compromised PCs at the Medical Center sent thousands of spam messages to addresses @columbia.edu with the subject "Invoice". Filtering at CUMC removed the bad zip file but allowed the altered message to be sent. Ironically because the bad zip file was gone the columbia.edu filter could not detect that the message was spam. The messages were harmless but annoying.
This morning, more of the same started coming in with the subject "new form". The columbia.edu filter is now detecting CUMC's modification and will block further messages of this type.
