More than 21,000 unencrypted usernames and passwords have been stolen from Australian surfwear company Billabong and posted online to CodePaste.net.
"At this stage, we understand that the customer database contains personal information of certain customers of the website, but no financial data," Billabong told SCMagazine in Australia. "We view this attack as an extremely serious matter and have taken urgent action to contain the incident and prevent further attacks occurring. We are continuing to gather information about the incident and to establish the extent and nature of the data that may have been accessed. We will take further appropriate measures as new information comes to light".
Hacktivists released the credentials under the banner of #WikiBoatWednesday, an operation popular in hacktivist Twitter circles where groups publish stolen data caches online.
Other administrator database tables and information was released, including hashed passwords.
The leak comes a day after news broke that more than 400,000 Yahoo passwords were published online.
