We, too, were scurrying around and called the Denver office for reassurance= before that message arrived from Valerie.
You mean that mail *purporting* to be from Valerie. Just some phishes are more intricate and well-played than others. :) I mean, look at these headers on the way to the listserv box: Received: from [64.18.1.35] by LISTSERV.EDUCAUSE.EDU (SMTPL release 1.0w) with TCP; Tue, 19 Feb 2013 12:16:50 -0700 Received: from mail.educause.edu ([208.42.249.152]) (using TLSv1) by exprod6ob115.postini.com ([64.18.5.12]) with SMTP ID DSNKUSPPog9AED1pIQwc6t0R2TWGyDwEE/iG () postini com; Tue, 19 Feb 2013 11:16:50 PST Received: from MAIL.educause.edu ([::1]) by MAIL.educause.edu ([::1]) with mapi id 14.01.0421.002; Tue, 19 Feb 2013 12:16:05 -0700 Listserv got it from a Postini box 64.18.1.35. Then there's a break, due to either poor header forging or a Postini server failing to add a Received line. And the Postini box says it got it from a machine claiming to be mail.educause.edu in the EHLO. But... % host 208.42.249.152 152.249.42.208.in-addr.arpa domain name pointer 208-42-249-152.static.data393.net. So that EHLO is just a tad suspect, because everybody knows that actual mail servers should have DNS PTR that look like mailservers and not generic addresses. :) Or am I just using waaay too much tinfoil lately? :) (For that matter, what reason do you have to believe this e-mail is actually from me? Your only realistic options are to check and maybe trust the PGP signature, or call our CISO, who'd tell you "Yeah, Val would totally write that mail" :)
