Correct, I don't believe that any of the providers noted are actually hijacking HTTP sessions instead all of these are DNS based tricks. Since the service providers are also providing DNS (via Paxfire and others) users don't have a lot of choice. You can switch to using a known public name server (Google's 8.8.8.8 for example) but I hesitate to recommend that to most end users because in non-evil networks its better to have local name resolution (because of GSLB other reasons).

Re: US internet providers hijacking users' search queries
I can confirm the report is about DNS providers that are doing hijacking by sending the traffic through dedicated proxies, either in the ISP's network or in the DNS provider's network. If you didn't see this happening, it might be because you were testing on www.google.com rather than on Yahoo or Bing traffic. While the hijacking *used* to affect Google also, we took a fairly aggressive stance and got it stopped a while ago. The fact that there are no currently-known cases where it affects Google was unfortunately not made clear in the Netalyzer/EFF reports. If any of you find evidence of hijacking of Google, please shoot me an email with details (DNS server, destination IP, etc) and I'll do what I can to get it stopped.

You're new here, aren't you? ;) Anybody who was around when a certain DNS provider started providing a wildcard for *.com and *.net so they could funnel the web page hits to their redirector shouldn't be surprised. Unless they're surprised it took this long to make the news again. pgpBqMOgLCy2z.pgp Description: PGP signature

You know what's going to happen. The regulators are going to get involved in response to things like this, with sufficient outcry from the public.Once ISPs show the industry can't be trusted to moderate itself, a new government body is likely to be formed for the sole purpose of passing as many arbitrary, arcane, bureaucratic, and otherwise burdensome rules ISPs will have to follow as possible. ISP's 'redirection' of certain search terms is proof that they have the full capability to block search terms, if it becomes widespread it would show that it's not unreasonable to demand ISPs intercept or block certain search queries. So eventually, there could be a government body saying what any ISP may do to search engine queries, and even mandating that ISPs do examine searches and block certain keywords or phrases -- -JH

The user behavior of searching in the address bar has become more common place, and browser behavior to try and resolve first, fallback to search for the same input field has both trained the humans to keep doing this and made it possible for DNS query interlopers to appear to be generic-search interlopers. -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE / NewNOG

Re: US internet providers hijacking users' search queries
Search engines are the ones that are paying for this redirection. Most of the companies that approached us about this technology partner with Yahoo for their error monetization. They want the eyeballs that come from redirecting these mistyped URIs. -Bradford Chatterjee On Fri, Aug 5, 2011 at 6:10 PM, Jimmy Hess mysi...@gmail.com wrote: I'd rather someone start making a blacklist of ISPs that inspect and modify packets in transit through their network in any way ( other than TTL decrementing ), so search engines could collectively identify these ISPs and choose to require _all_ connections from them be over SSL.
