Over the past few weeks we've seen a slow increase in SPAM messages related to stock market advice. We're starting to see regular reports from our users of this new ( for us ) activity. The messages are composed: 1) entirely of images --or-- 2) Images prepended with gibberish Messages have been received from computers around the world and sources don't seem to repeat. Our email system is assigning them junkmail scores too low to keep them out of regular mailboxes. Anyone else seeing these? If not, do you know what is keeping you from seeing them? Anti-spam device or product? ORB list? SPF? Custom filter? How would any SPAM filter be able to deal with a message made up entirely of an image and sent from varying computers? Is it safe to assume there are no filters that have OCR capabilities :) What actions do you take and/or what recommendations do you offer to users when faced with an increase in unfilterable messages? thanks, -- Gary Flynn Security Engineer James Madison University www.jmu.edu/computing/security
