ebay has confirmed that a large database containing encrypted passwords was hacked earlier in the year from one of their data centres! There is a possibility that the hackers will (or have already) decipher
the jumbled passwords and could use this to compromise the security of your account. Be especially aware if the username and password combo you use is the same over multiple sites (especially PayPal) and change all your relevant passwords as a matter of urgency. eBay has confirmed other unencrypted information was given away such as postal addresses and dates of birth, these could be used in identity fraud so keep a close on your bank statements etc. from in the near past and near future!
