LinkedIn: 'No customer accounts affected' 14 years ago
I don't buy it. My wife's yahoo email account, which shared a password with her linkedin account (yes, yes...), was accessed from abroad and used to send spam emails with a link, presumably to some exploit. While the password wasn't that great, it wasn't likely to be guessable or brute-forceable via login attempts.
Sounds like at least one affected customer to me...
