I know this is a whole different can of worms, but it sounds like it might =
be time to explore 2FA for your environment. As others have noted, we've ha=
d great results with focused education campaigns, but if it's becoming a co=
nstant problem for the entire campus it might be worth biting the bullet...

Subject: Phishing victims' turned into spammers


We are dealing with an issue where some of our users who are falling victim=
 to phishing emails are having their email accounts used to send more spam =
and phishing emails, to the point where our Exchange server and Barracuda E=
mail Security Gateway can't keep up, causing very long delays in legitimate=
 outbound email delivery.



The IT department has sent a number of messages out to our campus community=
 about the hazards of unsolicited document sharing emails, but we continue =
to have users entering their credentials online with little regard for secu=
rity. Our current process is to place user accounts in a pseudo-quarantine =
until their password is changed and their devices scanned for malware, but =
this only happens after we notice the mail queues filling up with hundreds =
of messages.



This cat-and-mouse game is wearing on the team, so I'd like some other pers=
pectives and advice on how to keep ahead of this type of attack and how to =
protect users against themselves and their trusting nature.
