We run our outbound mail through Symantec, which helps reduce the spam from compromised accounts...sometimes. If a message arrives with a URL from a web hosting site, and it has certain key words, we prepend a warning about phishing to the message body. We also block the URL's of identified phishing sites. The thing that really helps is we automatically monitor our outbound mail. When a user sends messages that exceed certain criteria, we get notified. We still have the occasional spam run that goes on, but, we usually have the user suspended within an hour. FWIW, we have relatively low numbers of victims say 10-20 a month. A targeted phish, might push those numbers up.

We've tried everything we can think of to educate faculty and staff to the fact that ITS never, ever asked them to revalidate their account by entering their username and password. But it still continues to happen and it looks like what folks are after is an account they can send SPAM through. If it's in the middle of a week-day we catch it pretty early , but evenings and especially week-ends, thousands of email messages with between 40 and 50 recipients each are sent out before we can kill it. So, we are constantly getting on blacklists. I can't imagine that Linfield College is alone in this situation. What are others doing to mitigate the consequences or better yet, prevent from occurring in the first place. Thanks. Rob Tanner UNIX Services Manager Linfield College, McMinnville Oregon ITS will never ask you for your password. Please don't share yours with anyone!
