Via the Telegraph:
Online auction site eBay is telling all 233M of its users to change their passwords following a “cyber attack” which compromised a database of account information. It is thought that hackers managed to access some eBay employee log-ins which gave access to the company’s corporate network. From there the attackers were able to access the database containing users’ information and steal the data. The company will be sending an email to each user today to notify them of the data breach and ask them to change their password. They will also be advised to change their log-in on any other websites if they used the same password there.
