[Chapter-delegates] Canadian ISP Rogers violates net neutralityby hijacking failed DNS lookups

FYI:

Phorm and its counterparts, NebuAd and others, have made and are continuing to attempt to make agreements with ISPs, including British Telecom and Virgin Media in the United Kingdom and Charter and WOW! in the United States, among several other ISPs.

These companies engage in "behavioral ad targeting", a practice that compiles "anonymized" profiles of network users' behaviors and serves "targeted" advertisements to those users via websites that agree to include Phorm/NebuAd code in their pages for this purpose.

In order to accomplish this, Phorm and NebuAd (among others) perform "deep packet inspection" of all network traffic in order to develop their profiles. This includes intercepting and modifying all packets, redirecting them through Phorm/NebuAd analysis programs hosted by the participating ISPs, and then releasing outbound packets to their original destination.

All inbound packets are inspected for (a) profile-matching identifiers and (b) participant destination identifiers. If a sequence of inbound packets matches both parameters (i.e. the profile is enabled for targeted ad receipt and the website is enabled for targeted ad injection), then the packets are modified to satisfy the goals of the ad server (Phorm/NebuAd) and the delivery mechanism provider (website).

These are so-called "opt-out" "services", as described by Phorm and NebuAd, where a cookie is placed on the user's machine when they make the effort to visit Phorm/NebuAd websites and follow the instructions to "opt-out" of the program. NOTE: This does not halt the "deep packet inspection" or analysis of the user's network activity, rather is simply informs Phorm/NebuAd of the user's preference not to receive any targeted advertisements. ALL packets continue to be inspected and routed through the analysis programs regardless of the user's "opt-out" status.

As you may surmise, once these systems are in place at the ISP, the ISP may then use the packet inspection processes for other purposes, including message delivery and service denial. The description in this thread of the activity related to observed rerouting could easily be the result of the use of these systems without any intrusion into the user's personal computing space.

Phorm and NebuAd, among others, are both in the process of being challenged by various governmental agencies, including the United States Congress in the U.S.A. and the European Commission, through its pressure on the British government to begin a serious investigation of Phorm's technology.

Please contact your country's authority in these matters and express your opposition to these seriously invasive systems.
