Because of this, most Auction House transactions completed are buyouts. Bidding on almost-expired items happens, but most people (especially under max level) are only buying items.
My buyout on Sunday still hasn't posted today.
Although how was I to know that?
I'm not convinced there's any actual security breach, but Blizzard has been doing a pretty terrible job of explaining the authenticators to their players.
"While no security method is 100% fool-proof (even Authenticators), please note that it is possible that players reporting to have been compromised while an Authenticator was attached to their Battle.net account may have been using the Dial-in Authenticator. The Dial-in Authenticator does not provide the same level of protection as the Battle.net Authenticator or Battle.net Mobile Authenticator app, and -- more importantly -- is not currently supported for Diablo III."

C'est la vie, I guess.
