At the risk of essentially slashdotting myself or making my web host very angry at me, I have stripped out the passwords so that the only component remaining is the email addresses, in case you want to check whether you were part of the breach. (I was not! hooray!)
I think these accounts were prior to Yahoo! Acquisition of associatedcontent. There is NO WAY for a "native" yahoo property to store plain text passwords. Of course this is a yahoo fault to buy a company with such a weak security...
If this was a leak in yahoo, the number of users with a yahoo e-mail would be much, much higher.
I presume that means also that the passwords could be different from the actual yahoo account passwords? Of course people might have kept them the same...
Could be blackmail gone unanswered (e.g pay us or we publish), could be hatred of Yahoo (either a competitioner, an employee, or just someone who feels wronged).
Or it could be a need to prove onself -- see what I can do, now fear my wrath.
Or it could simply be hatred of humanity, you embarrass people enough and they may lass out on you -- in this case by putting your password online, in other cases by bringing a gun to school.
Anyone know exactly what it means to be a yahoo voice user? I use yahoo chat, and I think I've used voice chat in the past, but I don't see my username in the dump drostie posted.
I guess its surprising that it does not cite a official press release from the company, (which is what you would normally expect), but to another news site. Also if one of your products faces such a crisis situation, would you want your users to read the company's reaction in such dispassionate, unapologetic language?
