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

Subject: [SECURITY] FYI -  Adobe account compromise

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.
