The Xbox Live service was not compromised ; Microsoft’s Major Nelson has been insisting following on from rumors that user data had been compromised by hackers.
"There have been a few isolated incidents where malicious users have been attempting to draw personal information from unsuspecting users and use it to gain access to their LIVE account", he said. "This is a good time to remind our members that they should never give out any of their personal information."
"Hope that clears things up", Major Nelson concluded.
