All,

  I hope ICANN is on top of this.  But somehow I doubt it.

See:
Yahoo!'s acquisition of open source mail client Zimbra has apparently
brought some baggage to the mail team. The new Yahoo! desktop
program
http://blog.holdenkarau.com/2008/09/another-security-devirsion-yahoo-zimbra.html
transmits the authentication information in plain text. The flaw was
discovered during a Yahoo 'hacku' Day at the University of Waterloo
(the only Canadian school part of the trip).  Compared to the recent
news about
http://tech.slashdot.org/article.pl?sid=08/07/16/2220232&tid=217 
Gmail exposing the names associated with accounts, this seems downright
scary. So, if you have friends or relatives who might have installed
Yahoo! desktop and value their e-mail accounts, now would be a good 
time to get them to change the password and switch back to the web 
interface.

  But this isn't the only problem with Yahoo.  Serious security hole
in Yahoo's DNS still remains unfixed.  One can only wonder why..
