For the second time this year Microsoft has been forced to issue a statement insisting that Xbox Live is safe.
The claims relate to allegations from US gamer Jason Coutee that a workaround exists that allows people to obtain a user ID confirmation from Xbox Live and then an unlimited number of attempts to gain access.
"Microsoft can confirm that there has been no breach to the security of our Xbox Live service,” a statement given to IGN reads. “The online safety of Xbox Live members remains of the utmost importance, which is why we consistently take measures to protect Xbox Live against ever-changing threats.
“Security in the technology industry is an ongoing process, and with each new form of technology designed to deter attacks, the attackers try to find new ways to subvert it. We continue to evolve our security features and processes to ensure Xbox Live customers information is secure.
“Online fraud and identity theft are industry-wide problems, and as such people using any online services should set strong passwords, not share those passwords across multiple services and refrain from sharing any personal details that could leave them vulnerable.”
Last week Microsoft was forced to calm claims that Live accounts were being exploited and then sold online.
