When passwords are stored in secure databases they are encrypted.
That means that anyone that has gotten hold of that database still has to de-crypt them to be able to use them. That is very difficult to do unless you also have the encryption keys/algorithms used to encrypt them in the first place.
So IMHO its of little concern that someone has obtained the passwords database. Its unlikely they can make any real use of them. It has been a number of months now since this break-in took place and there are no related reports of use of stolen passwords.
What is more concerning is that they might have also obtained your personal details stored on file that are not encrypted.
Things like: email addy, home address, phone numbers and the like.
So you may get bombarded with phishing attempts using these email addresses etc. But the usual rules apply:
NEVER click on links in embedded emails unless you are 110% sure of who the sender is and even then be careful. And hang up on phone calls if they are suspicious. Junk mail throw it out.
IMO its a big media beatup designed by ebay to get some free air time and advertising. People who may have not used their account in a long might log in to change their password and while they are at it, have a browse and buy.
