The group behind the latest threat is said to have posted several details on an IRC channel, claiming the attack may include customer information and credit card numbers, according to a CNET report. The individuals claim to have already gained access to Sony's servers.
The previous security issues included a distributed denial-of-service (DDoS) attack, which was organized by the vigilante group Anonymous. DDoS attacks merely cause problems for users attempting to access the company's websites, however the second attack, presumed to be spearheaded by a separate group, may have compromised credit card information from millions of subscribers.
The PSN breach has brought the attention of the US Congress and NY Attorney General, among other regulators. The company has been asked to provide detailed information regarding its security practices and any other details relevant to the PSN hack.
