Worried about your Xbox Live personal data? Don't be. Microsoft has moved to reassure its customers concerned about the protection of their data following the PlayStation Network hack that has seen personal details tied to some 77 million accounts stolen.

Microsoft told Eurogamer that "the security around our Xbox Live service and member information is our highest priority," but refused to comment further on the crisis that has afflicted Sony PlayStation. There are over 30 million registered Xbox Live accounts around the world.

Yesterday concerns were raised after Microsoft warned Xbox Live users of "phishing" attempts on secure data while gamers played smash-hit Call of Duty: Modern Warfare 2.

"Users may receive potential phishing attempts via title specific messaging while playing Modern Warfare 2," the Xbox Live Status page warned.

"We are aware of the problem and are working to resolve the issue.

"We apologise for any inconvenience this may cause and thank you for your patience."

The warning, which is still live, followed an apparent temporary lifting of Xbox Live bans on people who own a modified Xbox 360.

Applicable gamers were, for a short time, able to log back into Xbox Live, although the privilege was quickly revoked.

Some speculated that it was a result of Microsoft testing its own security in the wake of the entire PlayStation Network being compromised.
