The administration officials had been using a private Internet domain, called gwb43.com, owned by and hosted on an email server run by the Republican National Committee, for various communications of unknown content or purpose. The domain name is an acronym standing for "George W. Bush, 43rd" President of the United States. The server came public when it was discovered that J. Scott Jennings, the White House's deputy director of political affairs, was using a gwb43.com email address to discuss the firing of the U.S. attorney for Arkansas. Communications by federal employees were also found on georgewbush.com (registered to "Bush-Cheney '04, Inc.") and rnchq.org (registered to "Republican National Committee"), but, unlike these two servers, gwb43.com has no Web server connected to it — it is used only for email.
That would have been a hell of a spear phishing target. Imagine if you or I had sent emails to a million potential email addresses consisting of permutations of Bush's and his subordinates' names. We're talking about a bunch of middle aged guys who grew up without email. You'd think the chances of gaining access to a super high value computer system would be rather high. This should be a big deal whether it is done by GWB, Hillary, or anyone else.
