E-commerce giant eBay is urging customers to change their passwords after hackers broke into a database containing encrypted passwords in late February and early March.
The company said Wednesday that customers' passwords, emails, birth dates, and other identifying information emails were compromised after hackers gained access to the database using stolen employee login credentials.
It said that it has not found evidence of suspicious financial activity on customers' eBay or PayPal accounts, because that information is stored in separate databases.
EBay said the number of people affected by the data breach is unknown. EBay reported 145 million active buyers last week, while its subsidiary PayPal reported 148 million active accounts.
The company said it became aware of the cyberattack two weeks ago, and has since brought in a team of security experts to investigate the incident and secure customer information.
