Cyber criminals come out with new attacks all the time and the best defense against them is education and vigilance. Please pay close attention when you see emails that refer to account upgrades, webmail, help desk mandates, or the like. These are SPAM and a form of email phishing that targets specific user communities. Spammers use public information to lure unsuspecting recipients to sites requesting NetIDs and passwords, or to sites that install malware on computers that may in turn steal local information from the computer.
