Re: EDUCAUSE Statement on Server Breach

I actually just ignored all reset links in the email and went directly to the Educause site. Only to then still be 
prompted via email to follow a link to reset my password since you could not use your old password or get a 
verification code via phone. *grumble*

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

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" 
:)
