A hacker group has released a cache of 13,000 passwords, usernames, and credit cards purporting to belong to users of popular web services including Amazon, Xbox Live and PlayStation Network.
The group says it is affiliated to the Anonymous internet movement, which has no central leadership, structure, or official membership.
The information was uploaded in a text file to a filesharing site called Ghostbin; it is no longer accessible.
Users of Amazon, Walmart, PlayStation Network and Xbox Live, as well as a number of pornography websites, are among those who could be affected.
In a message posted on Twitter, the group said it “did it for the lulzâ€, an online slang expression implying something which was done for general amusement.
The Independent approached Microsoft, Sony, and Amazon for comment but did not receive an immediate response from any of the companies.
Anyone who believes they are at risk should change their password on the suspect service and contact their credit card issuer.
The incident comes hours after the resolution of outages caused by cyber attacks on PlayStation Network Xbox Live system.
The systems had been down since Christmas Eve when a group known as Lizard Squad began a DDOS (distributed denial of service) attack on the gaming platforms.
Film company Sony Pictures was also targeted by hackers suspected of having links to the North Korean government.
Internet connections across North Korea itself have also been having major problems, which the country’s government has blamed on the US government
