http://sophos.com/adobe doesn't resolve...

But this seems like a likely candidate for the article Brian referenced:

There's an excellent description at sophos.com/adobe and on this week's Security Now podcast.

FYI

Per http://xkcd.com/1286/ and others, hackers have leaked 130 million user records from Adobe, containing email 
address, 3DES encrypted password, and hint, with lines like:

63498551-|--|-mxxxxxxx () wisc edu-|-eYxxxxxxxxxxxxx==-|-kunsan cutie|--

2 million of these are .edu addresses

From what I have read, the passwords are encrypted using a symmetric key but the key is unknown. For now. As a mailing 
list for spam, it needs washing, badly.

All that user education is having some effect, at least.
The most popular password is now "123456", an improvement over "12345" a couple of years ago and "1234" before that.
Per http://stricture-group.com/files/adobe-top100.txt

I'm not sure it's really a big cause for concern, though I guess a lot of people use the same password for everything 
and there's their password hint "dog's name" sitting out there. The etymology of user names on Hotmail should we worth 
a sociology paper or two.
