Comcast Xfinity Wi-Fi Discloses Customer Names and Addresses

itwbennett writes: Despite assurances that only business listings and not customer names and home addresses would appear in the public search results when someone searches for an Xfinity Wi-Fi hotspot, that is exactly what's happened when the service was initiated 2 years ago — and is still happening now, writes CSO's Steve Ragan. And that isn't the only security issue with the service. Another level of exposure centers on accountability. Ken Smith, senior security architect with K Logix in Brookline, Ma., discovered that Comcast is relying on the device’s MAC address as a key component of authentication.
