Microsoft has warned users of its Xbox Live online gaming service of possible attempts to steal sensitive personal information after the Sony PlayStation Network was hacked.

A few days ago, the Playstation Network faced an intrusion by a hacker who stole personal user information such as credit card numbers for nearly 77 million users. The popular game Modern Warfare 2 was used by the hackers to try potential phishing attempts, according to Microsoft.

Though Xbox Live allows Xbox 360 console users to download games and music and play online against other gamers but they have warned users to keep eyes on what's happening.

Now, Sony's Playstation Network and Qriocity streaming music service has been offline for more than a week. Sony said, "We are aware of the problem and are working to resolve the issue. We apologize for any inconvenience this may cause and thank you for your patience."
