Comcast Domain Helper: Here to hijack, er, I mean, help, you!

Comcast rolls out nationally its "Domain Helper" service, which is nothing more than a thinly veiled traffic hijack scheme.

Not long ago, I started seeing what I thought was a new search provider in my web browser.  But, I was puzzled while reviewing my browser settings—there seemed to be no mention of any Comcast-related search provider.

If you’re a Comcast customer, you, too, may have started noticing screens like this:

As it turns out, Comcast has rolled out nationally a “service” they call, “Domain Helper”.  What Comcast has actually done is to hijack any requests that return an error and redirect them to their own branded search/advertising page.

By slipping this in as the default on their network, with a poorly publicized opt-out mechanism (rather than offering it as an opt-in program), they appear to be banking on the fact that most uses won’t understand that they have been hijack.

Opting Out

If you’re a Comcast customer, you can use the opt-out mechanism to turn off the Domain Helper feature.  You’ll need to know you Comcast login credentials (but if you don’t know them, there is a link where you can find them.)

Spreading the Word

It’s troubling when the network provider is also an advertising/content provider as it creates a real conflict of interest.  In this case, that conflict of interest caused Comcast to silently redefine the way the web works for millions of people.

Please share this information with other Comcast users via your social networks, e-mail, blog, or the various sharing tools on this site.
