As if you needed yet another reason to loathe your ISP, Comcast has dropped the ball when it comes to properly securing its own wireless products. A pair of security researchers have uncovered a bug on Comcast's website that allowed unauthorized disclosure of Xfinity customers' personal data, according to a report from ZDNet. All you needed to ruin someone's day (or gain unauthorized access to their home network) was an account number and a partial address. Terrible timing, considering Comcast is in the process of launching its own line of mesh network routers.
