I'm not sure if it's considered a breach. I read somewhere about this last night, it seems the guy was crawling leaked usernames/password combinations and adding them to a list. But he may have gotten into something, too. If he hacked all of Yahoo Gmail Mail.ru, and gotten that many email/pass combos out of it, that's pretty awesome actually.

Must have been doing it for a while, too, to have gotten so many of them.

Agreed. Microsoft and Google would alert users.
