EBay has asked users to change their passwords following a cyberattack that compromised one of its databases.
The US firm said the database was hacked between late February and early March, and had contained encrypted passwords and other non-financial data.
The auction site added that it had no evidence of there being unauthorised activity on its members’ accounts.
However, it said that changing the passwords was “best practice and will help enhance security for eBay users”.
EBay’s shares fell after the company disclosed the attack.
“For the time being, we cannot comment on the specific number of accounts impacted,” eBay spokeswoman Kari Ramirez said. “However, we believe there may be a large number of accounts involved.”
Below is the eBay announcement posted on its website:
eBay Inc. (Nasdaq: EBAY) said beginning later today it will be asking eBay users to change their passwords because of a cyberattack that compromised a database containing encrypted passwords and other non-financial data. After conducting extensive tests on its networks, the company said it has no evidence of the compromise resulting in unauthorized activity for eBay users, and no evidence of any unauthorized access to financial or credit card information, which is stored separately in encrypted formats. However, changing passwords is a best practice and will help enhance security for eBay users.
Information security and customer data protection are of paramount importance to eBay Inc., and eBay regrets any inconvenience or concern that this password reset may cause our customers. We know our customers trust us with their information, and we take seriously our commitment to maintaining a safe, secure and trusted global marketplace.
Cyberattackers compromised a small number of employee log-in credentials, allowing unauthorized access to eBay’s corporate network, the company said. Working with law enforcement and leading security experts, the company is aggressively investigating the matter and applying the best forensics tools and practices to protect customers.
The database, which was compromised between late February and early March, included eBay customers’ name, encrypted password, email address, physical address, phone number and date of birth. However, the database did not contain financial information or other confidential personal information. The company said that the compromised employee log-in credentials were first detected about two weeks ago. Extensive forensics subsequently identified the compromised eBay database, resulting in the company’s announcement today.
The company said it has seen no indication of increased fraudulent account activity on eBay. The company also said it has no evidence of unauthorized access or compromises to personal or financial information for PayPal users. PayPal data is stored separately on a secure network, and all PayPal financial information is encrypted.
Beginning later today, eBay users will be notified via email, site communications and other marketing channels to change their password. In addition to asking users to change their eBay password, the company said it also is encouraging any eBay user who utilized the same password on other sites to change those passwords, too. The same password should never be used across multiple sites or accounts.
