Independent developer Kevin Burke warned Virgin Mobile USA customers about a glaring security hole in the phone company’s account login protocol. Burke: “If you are one of the six million Virgin subscribers, you are at the whim of anyone who doesn’t like you” Virgin Mobile users manage their account by logging in through an online portal, which requires a mobile number and a 6-digit pin.
