Microsoft has confirmed that it is investigating potential fraud on its Xbox Live service after a string of complaints from users who claim that their credit card details have been used to purchase Microsoft Points online.

CVG reports that a Microsoft spokesperson admitted: “Recently, there have been reports of fraudulent activity and account theft taking place on the Xbox Live network. Security is a top priority for Xbox Live, and we are actively investigating all reports of fraudulent behaviour and theft.”

However, Microsoft did add that the breach of security may not necessarily be linked to the Live Arcade infrastructure, and could instead stem from an email phishing scam.
