What is problematic is that TWC(NYNJ) subscribers may be put at risk unwittingly as a result of the lockdown policy on leased eMTAs.
Specfically, the ARRIS TG862G which can be leased with wifi enabled, (marketed as Home WiFi - with a monthly surcharge of $5.95) is configured by default with publicly known PSKs. If the subscriber cannot change those defaults, their internal network can be easily compromised, an intruder can steal their bandwidth, and crimes may be committed using the subscibers broadband connection, for which the subscriber will be initially blamed. This is a major exploit and needs to addressed ASAP. It's also "out in the wild" as a result of an Forbes article that was published this past July (2012), detailing the default PSKs, the components of which are being broadcast in the clear.
This is why it is critically important to either allow the subscriber to change the default PSK or for TWC to provision the eMTA with default PSKs that can't be sniffed or hacked.
