ISPs will attach your ZIP to all web requests

Wednesday, June 23rd, 2010

This Article on Wired.com is about an initiative by Juniper Networks in collaboration with Feeva to sell a new tracking technology to ISPs.

The enhanced router would be sold to ISPs and will automatically insert your ZIP+4 into HTML headers. This will allow marketers to have much more accurate information about the user’s physical location.

They claim that the “consumer is not in any way stripped of their privacy” but fail to actually explain how that is the case. The point is for ISPs to get a piece of the advertising pie. The ZIP will be encoded, not sent in the clear, but will be available to some undefined set of “trusted third parties”. That does not give me much comfort.

I have seen many examples of websites which charge different prices based on where you live, or otherwise restrict access to web pages. This kind of targeting does not help me at all. If I want to be located, I have many ways of explicitly telling the site where I am.

This is another example of why you can’t trust your ISP. Their interests are not the same as yours. They have a strong incentive to track and monetize your activity.

Fortunately it is easy to take back control. If your traffic is encrypted within a VPN, then the ISP will be unable to insert this information. It gives you the absolute ability to enforce your own “opt out” even if the ISP does not want to give you the option. Anonymizer Universal(TM) provides an easy tool to accomplish this.

 

TOR may actually reduce your privacy

Wednesday, June 2nd, 2010

WikiLeaks seeded its database of documents by intercepting traffic through a TOR node they were operating.

This article at Wired highlights an almost buried section of this New Yorker interview with one of the founders of WikiLeaks.

Before the WikiLeaks site went live, the founders noticed that hackers were transferring stolen government documents over the TOR network. They captured over a million of these documents to form the initial core of the WikiLeaks archive.

This shows once again what I have been saying for a long time. Any privacy system that allows any untrusted and unknown person to become part of the infrastructure and have access to cleartext information is fundamentally flawed.

Any person with malicious intent can easily set up a TOR node and begin exactly the same kind of data collection that the WikiLeaks folks practiced.

Reputation is everything in this business. It is not practical for typical individuals to properly vet their providers. Track record, reputation, and respected third party endorsements are your best bet when choosing a privacy or security provider. Look for those for everyone who has access to your information.

Privacy and Corporations at CFP Conference

Wednesday, May 26th, 2010

I am very excited to be organizing a couple of panels at this year’s “Computers Freedom and Privacy” (CFP) Conference in San Jose June 15-18.

Historically the conference has focused on personal privacy / freedom issues, technologies, and policies. That was certainly my focus as well when I started Anonymizer. Over time I have become aware of some other aspects to the privacy issue that I have not seen discussed. In addition to corporations impacting privacy of their customers, users, employees, etc. they also have issues and needs for privacy themselves.

Companies activities are monitored, analyzed, blocked, misinformed, and censored. While these have analogs in the personal privacy world, the details, impacts and scale, and solutions to the problems are often very different.

I am organizing a panel to discuss these issues at the conference and would love to hear from others who may have experienced these kinds of issues and would be willing and able to share them at this conference.

Cypherpunk retrospective at 20th anniversary CFP conference

Wednesday, May 26th, 2010

This year the “Computers Freedom and Privacy” (CFP) conference is taking place in San Jose from June 15-18. This year is the 20th anniversary of the conference which helped shape my thinking about Internet Privacy and introduced me to many of the key players in this space.

Around the same time in 1992 an email mailing list started called “Cypherpunks”. Members were devoted discussions of Internet freedom and to creating and distributing privacy and security tools. Best known of these are the various flavors of Anonymous Remailers following the original anon.penen.fi.

This seems like a good time to stop and take stock of what has been achieved, lost, and abandoned in the evolution of privacy and anonymity on the Internet. I have organized a panel at CFP of some of the key Cypherpunks from the early days to talk about those early days, and share their vision and insight about where we are and where we should / are likely to end up.

I hope I will see many of you there.

IntelFusion - Use a proxy server. Feed an Intel service.

Thursday, April 29th, 2010

Read this post from IntelFusion. It makes a very strong case for why I worry about any privacy system run by operators you can’t really trust, investigate, and verify. In this case it is an investigation of Glype servers. They can be configured to do significant logging, and the author has been able to remotely retrieve the logs from many of the Glype servers. The results show many users from within sensitive US Government organizations and would provide the ability for an attacker to gather all kinds of useful intelligence to find soft targets to exploit.

On the personal privacy side, it is an easy way for attackers to intercept usernames, passwords, travel plans, personal information and more for use in, identity theft, burglary, and hacking among other things.

Lauren Weinstein’s Blog: Saving Internet Anonymity — The Struggle is Joined

I strongly encourage anyone with a commitment to Internet anonymity to read this blog post. An organized opposition to the existence of such anonymity is growing. Of course, like attempt to clamp down on cryptography, it will only impact the law abiding while criminals use bots and other tools to circumvent the restrictions.

Between this and the push to remove the expectation of privacy from all stored emails, I am very concerned.

Pseudonyms: The Natural State of Online Identity | Privacy Digest

This article does a nice job of making a point I have been talking around for some time. The Internet naturally supports pseudonymity, and that is really what we want most of the time. When I talk to someone on-line, I am most interested that I am still talking today with the person I started talking to last month. Whether the name actually corresponds to their birth certificate is not important (and I would not have any idea in a real world encounter either).

Tor partially blocked in China

Tor partially blocked in China | The Tor Blog

That last article lead me to this post on the TOR blog from September 15, 2009 (I am a bit late to this party). China is now blocking about 80% of the public TOR nodes.

This mostly ends a rather baffling situation where for some reason the Chinese were failing to block TOR even though it was being used effectively for censorship circumvention, the list of nodes is publicly available, and they are no more difficult to block than any other server.

Privacy Network Tor Suffers Breach | Privacy Digest

Privacy Network Tor Suffers Breach | Privacy Digest

It has been reported, and the TOR folks have confirmed, that two of their core directory servers were recently compromised along with another server showing usage metrics. While it does not at first appear that the attack was aimed at compromising the TOR network, it would certainly have made some interesting attacks possible. Specifically, it looks like it would have allowed attackers to force users on to chains of all enemy run nodes. This is very concerning.

It also brings us the issue of general security of the TOR nodes. Since they are mostly run my volunteers, the security of the nodes is going to be very inconsistent. It is likely that many of them are vulnerable to attack which would give an adversary the ability to control a much larger fraction of the TOR network.

Once Again, Google is in a tricky spot with censorship, this time in India.

Google and India Test the Limits of Liberty - WSJ.com

In this case, it is not the search engine, but their social networking site “Orkut” which is the issue. Google’s troubles stem less from their actions than the fact that they are the dominant social networking site in India, and so most of those issues happen on that site.

Google has been forced to take down a lot of content, and hand over the identities of many posters. If the examples in the article are to be believed, the threshold for censorship is not high.

At the risk of repeating myself, if you live in India and you want to say something that might push or cross the line, do it with robust anonymity technology. You might still have your post taken down, but they can’t come after you.
