An Open Response to NebuAd  
Dear NebuAd,

In your statement regarding my recent report, “NebuAd and Partner ISPs: Wiretapping, Forgery and Browser Hijacking” you state the following:
"Transparency and consumer-privacy protection are core to our business. Reasonable review of materials that have been made available online would have educated the organization that NebuAd requires its ISP partners to provide robust notice to their subscribers prior to deployment of the service."
For the record, I would like to make it clear that:
"All ad networks use a small piece of code that is temporary and operates only within the security framework of the browser to invoke the placement of ad network cookies. The code NebuAd uses is no different, and is clearly demarcated outside of and does not modify any publisher code."

This, too, requires a response.
  • As mentioned in my report, NebuAd injects its cookies by forging TCP packets using a hardware device in the middle of the network.  This is not something that all ad networks do.
  • As detailed in my report, NebuAd's code is appended to the web page code, in an extra packet that appears to come from servers owned by Google or Yahoo (not NebuAd).  This is why you can claim any demarcation. However, there is no demarcation between the publishers code and your injected code that indicates that the code is not from the publisher and that NebuAd is the source of the injected script.  The packet is a forgery and the reason is obvious -- if the injected packet would properly identify its source in the IP header, the customer's computer would properly ignore it. This is by intentional design, and is why I characterize NebuAd's programming as usurping the intentions of the application and operating system designers.
Having read this response, I expect that you will stop misinforming the public about my report.  This matter deserves debate, not disinformation.

Sincerely,

/s/

transparency is a 2 way street
Does Google reveal their customer names? How bout MicroHoo? Those guys own EVERYTHING you ever searched for -- EVER. and they sell it off and leverage it to deliver ads based on reading your email and web searches.

Re: transparency is a 2 way street
If I use Google, it is by my choice. I could use Ask, MSN, or Yahoo, instead.

And since you mention Google, I know that any record that they keep on me is kept for 18 months before being purged. I know that because I can read their privacy policy that appears on any Google-owned web site. This is not true when the system is spying from the middle of the network. Google is avoidable, NebuAd is not.

As for NebuAd, most of the ISPs won't reveal that they use NebuAd and NebuAd doesn't reveal which ISPs are their partners. While they make statements as to how they handle data, it does not answer the question as to under what authority they should even see the data in the first place! The ISP has no right selling every byte users send and receive to NebuAd.

This would be like Comcast monitoring my Internet traffic or phone calls so they can decide what ads to show me on television. That would be DUMB -- talk about a triple-play breaker!
