The Privacy Blog Podcast – Ep.7: Blacklisted SSL Certificates, Social Media Hacking, and the “Right to be Forgotten” Online

Welcome to episode 7 of The Privacy Blog Podcast. In April’s episode, we’ll be looking at the blacklisting of SSL certificate authorities by Mozilla Firefox - Specifically, what this complex issue means and why Mozilla chose to start doing this.

In more breaking online privacy news, I will be discussing the security implications of relying on social media following the hacking of the Associated Press Twitter account earlier this week.

Next, I’ll chat about the “right to be forgotten” on the Internet, which hinges on the struggle between online privacy and free speech rights. In a closely related topic and following Google’s release of the new “Inactive Account Manager,” I will discuss what happens to our social media presence and cloud data when we die. It’s a topic none of us likes to dwell on, but it’s worth taking the time to think about our digital afterlife.

A new "modest proposal" for the Internet

In the tradition of Jonathan Swift's "A Modest Proposal" is "The Dictator's Practical Guide to Internet Power Retention, Global Edition".

Under the pretext of being a guide on how to crack down on Internet dissent for dictators, it does a nice job of analyzing how the Internet is used by dissidents, and the techniques used by governments to crack down on those practices.

Thanks to boingboing for bringing this to my attention.

My philosophy on privacy and anonymity

I have recently seen chatter suggesting people are confused about my thinking and allegiances on various privacy issues. First, a few core beliefs that form the axioms underlying my actions and positions.

I believe that:

• The basic design of the Internet and the protocols that run on top of it make it the most privacy hostile major communications media ever used.
• Censorship and widespread surveillance are inimical to free speech and free expression.
• Personal privacy is critical to our social, societal, and mental health.
• There are criminals, terrorists, and governments whose activities will undermine the quality of life for myself, friends, and family.
• Law enforcement and intelligence organizations are a necessary part of a functioning society.
• Governments and other organizations are made up of real people with real and diverse opinions and are not monolithic entities and edifices of conformity.
• If data is valuable to someone, and is sitting around in a database or other storage, it is very likely to be compromised at some point, in some way.

So, these basic tenants lead me to take the following opinions:

Individuals need the ability to robustly protect their privacy when engaging on-line. While not all areas of the Internet are appropriate for anonymity (I really want my bank to make sure it is me accessing my accounts), anonymity / pseudonymity should be an option in most social spaces on the Internet.

Not only are most websites not inclined or incentivized to help you be anonymous, but the very structure of the Internet encourages detailed logging such that creating anonymity friendly systems is quite hard.

All providers of privacy services are fundamentally saying “trust me and I will protect you.” Any claims about how a service works rely on the operator to have actually implemented the system as claimed. At the end of the day this is only backed up by the reputation of the operators of those systems. Choose wisely.

Criminals and other “hostiles” are indiscriminate in their use of technologies. They will use the best tool for any job. The Internet is no exception to this rule. While there is a long history and extensive precedent for plain clothes and under cover police and intelligence activities in the meatspace, the same is not true for cyberspace. Yet, the same need applies. If one is trying to engage with a criminal on the Internet, doing so as a law enforcement officer, from known law enforcement IP addresses is going to imperil the investigation at the very least.

What does this mean for me and how I comport myself?

I have chosen to very publicly back the Anonymizer.com privacy services with my personal reputation. I have been active in the personal privacy space since I started running anonymous remailers as a grad student in 1992. I have been creating new privacy services since I wrote Mixmaster in 1993. I created the “Kosovo privacy project” during the Kosovo conflict to enable people in the country to report on atrocities going on. I have provided multiple anonymity and anti-censorship tools for the Chinese and Iranian people, protecting hundreds of thousands of their citizens against their own country. Human rights and free speech are passions of mine. Anonymizer.com itself has protected countless numbers of users of its services. In all that time there has never been a case where we have violated the privacy assurances we have made to our customers. This is not because we have not been tested. Anonymizer is regularly subpoenaed for information on our customers’ activities. Compare this to a relative newcomer “HideMyAss.com.” They, as it turns out, did keep logs and were compelled to compromise the privacy of a member of LulzSec. There are numerous examples of TOR exit nodes monitoring and even altering traffic. With a much longer and weightier track record, you will find no such incidents with Anonymizer. It is logically impossible to prove a negative, but our history speaks volumes. Anonymizer will never provide a back door or violate any of our privacy assurances while my name is attached to it. Reputation is hard to earn and easy to squander. It is my personally most valuable asset.

Law enforcement and other government entities need anonymity and pseudonymity tools too. In their cases the people trying to pierce the veil are often much more motivated, skilled, funded, and resourced, than those tying to identify ordinary individuals. It is not practical, reasonable, or desirable to have these groups simply ignore the Internet in the scope of their responsibilities I have been involved in the creation and operation of numerous tools to enable such organizations to do their jobs on-line as they do off-line. In working with these people I have discovered that they are “people.” They hold diverse opinions about privacy and anonymity. Many are personally closely aligned with my beliefs. They are also tightly constrained by legal limitations on what they can do. Watching my U.S. government customers struggle with their legal departments to do even the simplest and most innocuous activities, while very frustrating, makes me sleep much better at night.

While there have certainly been times when the U.S. Government has overstepped its authorities, they are rare, and we know about these because they came out. The diversity of people in these organizations makes any of the grand conspiracies I see discussed on the Internet absurd on their face. Secrets are either known by very few people and thus limited in scope, are reasonable to just about everyone who all agree they should be kept secret, or will get leaked or blown in some way.

Some users of my personal / consumer privacy services see themselves as in opposition to some or all of my corporate or government users, and vice versa. I think both are important and I protect the anonymity of all of my customers equally. There is no “crossing of the streams.” None of my customers get any special insight into the identities or activities of any of my other customers. As above, there are no secrets like that which would last very long, and it would destroy my reputation.

Honor, reputation, and a man’s word being his bond may be very old fashioned ideas these days, but they carry great weight with me. I hope this clarifies where I stand.

Facebook "Like" not protected speech in Virginia

Courthouse News Service reports that a virginia judge has ruled Facebook "Likes" are not protected speech.

The case was related to employees of the Hampton VA sheriff's office who "Liked" the current sheriff's opponent in the last election. After he was re-elected, he fired many of the people who had supported his opponent.

The judge ruled that posts on Facebook would have been protected, but not simple Likes.

India asks social network sites to manually screen all posts.

The NYTimes.com reports that Kapil Sibal, the acting telecommunications minister for India is pushing Google, Microsoft, Yahoo and Facebook to more actively and effectively screen their content for disparaging, inflammatory and defamatory content.

Specifically Mr. Sibal is telling these companies that automated screening is insufficient and that they should have humans read and approve allmessages before they are posted.

This demand is both absurd and offensive.

• It is obviously impossible for these companies to have a human review the volume of messages they receive, the numbers are staggering.
• The demand for human review is either evidence that Mr. Sibal is completely ignorant of the technical realities involved, or this is an attempt to kill social media and their associated free wheeling exchanges of information and opinion.
• There is no clear objective standard for "disparaging, inflammatory, and defamatory" content, so the companies are assured of getting it wrong in many cases putting them at risk.
• The example of unacceptable content sighted by Mr. Sibal is a Facebook page that maligned Congress Party president Sonia Gandhi suggesting that this is more about preventing criticism than actually protecting maligned citizens.

PM David Cameron on censorship: bad when you do it, OK when I do it.

Back in February, British Prime Minister David Cameron gave a speech where he strongly opposed the censorship and crack down on protesters in Egypt.

For decades, some have argued that stability required highly controlling regimes, and that reform and openness would put that stability at risk. So, the argument went, countries like Britain faced a choice between our interests and our values. And to be honest, we should acknowledge that sometimes we have made such calculations in the past. But I say that is a false choice.
As recent events have confirmed, denying people their basic rights does not preserve stability, rather the reverse. Our interests lie in upholding our values - in insisting on the right to peaceful protest, in freedom of speech and the internet, in freedom of assembly and the rule of law. But these are not just our values, but the entitlement of people everywhere; of people in Tahrir Square as much as Trafalgar Square.

Now, with the riots in England he feels that restricting access to social media, and censoring free speech is necessary to maintain order.

Everyone watching these horrific actions will be struck by how they were organised via social media. Free flow of information can be used for good. But it can also be used for ill. And when people are using social media for violence we need to stop them. So we are working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these websites and services when we know they are plotting violence, disorder and criminality. I have also asked the police if they need any other new powers. Police were facing a new circumstance where rioters were using the BlackBerry Messenger service, a closed network, to organise riots. We've got to examine that and work out how to get ahead of them.

It is easy to condemn censorship in others, but it seems expedient when one is trying to control one's own population. When in power, the difference between justifiable actions and tyranny is largely a matter of "us" vs "them". "We" are good and would not abuse this power while "they" use censorship to keep the boot of oppression on their people.

The trouble is, it is very hard to know when one has moved past the tipping point, and powerful self justification comes easily to intelligent leaders and their advisors. As has been said many times "no man is the villein of his own story".

This is a Rubicon I hope the UK can hold back from crossing.

Debate about activist need for anonymity on Facebook

Amid unrest, a hard new look at online anonymity | The Social - CNET News:

This article takes an interesting look at the issues with Facebook's true name policy and the impact it has on activists and dissidents in repressive countries. It quite rightly talks about the fact that for most of the history of the Internet use of "screen names" was the default.

The odd thing about this debate is that there is basically no authentication of the names used. Many people assume that since most users are under true name that all of them are. It is trivial to set up a new account with a plausible name which can not be traced back to the real user.

I would hope that dissidents, activists and others at risk would take advantage of this simple capability to protect themselves. Yes, this is in violation of the terms of service, but I think it is for a much greater good.

If you choose to do this, take care with who you friend under this alias. If the social network you create matches your real one, or that of another account, it may be very easy to unmask your identity.

Eric Schmidt against Anonymity

In this interview with Eric Schmidt, CEO of Google, comes out very strongly against anonymity starting at about 5:10 in the video. His argument is that: "If you are trying to commit a terrible evil crime it is not obvious that you should be able to do so with complete anonymity." The problem is that absolute and complete anonymity is easy for criminals. There is a robust economy in stolen account, botnets, stolen credit cards, open networks and other capabilities that enable absolute anonymity for anyone willing to violate the law. It is only anonymity for the law abiding that is difficult, and the reason Anonymizer exists. Arguing against anonymity is, for all practical purposes, only arguing against anonymity for legitimate purposes while it thrives for illegitimate purposes.

I will spare you the lecture on the history of anonymity and anonymous speech dating back to the founders of the United States.

BTW, this was delayed for a while while I struggled with getting embedding working within WordPress. It seems to be working now on FireFox, but not when I view in Safari. Please comment with how I am being stupid if you know what is going wrong.

Cypherpunk retrospective at 20th anniversary CFP conference

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.

Saving Internet Anonymity -- The Struggle is Joined

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.

Google Stops Censoring in China

From the Official Google Blog (follow link for the whole post):

So earlier today we stopped censoring our search services—Google Search, Google News, and Google Images—on Google.cn. Users visiting Google.cn are now being redirected to Google.com.hk, where we are offering uncensored search in simplified Chinese, specifically designed for users in mainland China and delivered via our servers in Hong Kong. Users in Hong Kong will continue to receive their existing uncensored, traditional Chinese service, also from Google.com.hk. Due to the increased load on our Hong Kong servers and the complicated nature of these changes, users may see some slowdown in service or find some products temporarily inaccessible as we switch everything over.

I would expect to see China censor Google.cn very quickly (which would prevent the re-direct to Google.hk). It will be interesting to see if China will then take the next step of censoring Google.hk and possibly other Google properties around the world. It would be easy for Google to set up any or all of them to return results in chinese if the browser is detected to be configured in that language.

Google human rights accounts attacked from China

Official Google Blog: A new approach to China Google is officially stating that a number of email accounts hosted by Google were attacked from within China. The accounts seem to be mostly connected to Chinese human rights activists. They also state that this is part of a larger pattern extending over a number of other companies.

The most amazing thing about this is the very aggressive pro-privacy stance Google is taking in response to this. They are saying that they will stop censoring search results at Google.cn. That they will talk with the Chinese about how to do this, but are willing to completely pull out of operations in China if they can't provide un-censored content from within.

The post is worth reading in full. Here are the concluding paragraphs:

These attacks and the surveillance they have uncovered--combined with the attempts over the past year to further limit free speech on the web--have led us to conclude that we should review the feasibility of our business operations in China. We have decided we are no longer willing to continue censoring our results on Google.cn, and so over the next few weeks we will be discussing with the Chinese government the basis on which we could operate an unfiltered search engine within the law, if at all. We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China.

The decision to review our business operations in China has been incredibly hard, and we know that it will have potentially far-reaching consequences. We want to make clear that this move was driven by our executives in the United States, without the knowledge or involvement of our employees in China who have worked incredibly hard to make Google.cn the success it is today. We are committed to working responsibly to resolve the very difficult issues raised.

Wow. We shall see.

Question from a long time customer

A long time customer recently sent in the following question. Since it should be of broad interest, I asked his permission to anonymous post and answer it here.

How do you know that subscribing to an anonymizer does not simply mark you for observation? We all know the NSA is capable of intercepting any electronic communication, and with gajillions of electronic communications happening every second, how would the NSA (or the FBI or the CIA or whoever it is who watches us) know which of those communications to watch? Seems like the people wanting anonymity would be the first on the list. Surely they COULD, couldn't they? That is, get the subscriber lists, which would enable them to intercept communications this side of the proxy - i.e., intercept on the way out, on the way TO the proxy, BEFORE it gets securely tunneled? And no, that would not be possible with the web, but it would with email. Supposedly. This is what has been proposed to me. What do you think? Does it have any validity?

It is certainly the case that the government could, in principle, monitor your access to privacy services. As long as that access is over a strongly encrypted connection, the contents of your communication, what sites you are visiting or who you are communicating with would be protected. The strength of your anonymity is then largely determined by the number of other users of the same service with which your traffic is being mixed.

In the United States, the use of privacy tools is not restricted. Strict separation of intelligence from law enforcement functions should prevent drift net monitoring of your use of Anonymizer from leading to any kind of legal investigation. The huge number of Anonymizer subscribers would also make this difficult and highly visible.

Outside of the US it is another story. Many countries exercise much greater control over the Internet. Even if it were not blocked by the Iranian government, accessing the Anonymizer website from within Iran would be a risky activity. Once again, the key here is safety in numbers. We have run anti-censorship tools in Iran that supported over 100,000 users. With those numbers, it is awkward for the government to go after people simply for using the service. This is not to say that if you are already under observation for some other reason that it would not give them added ammunition. Privacy tools are generally very effective at keeping you below the radar, but can be much less effective once you are on the radar for whatever reason.

The reality is that there is no evidence of widespread Internet surveillance being used in the US to track users of privacy services. As long as the connection to the service is well encrypted, you should be fine.

Argentine judge: Google, Yahoo must censor searches | Latest News in Politics and Law - CNET News

Argentine judge: Google, Yahoo must censor searches | Latest News in Politics and Law - CNET News There is a disturbing trend towards increasing regulation of the Internet. In this case, Argintine judges have ordered Google and Yahoo to remove certain search results related to various individuals. This appears to be a back door way of removing the content without actually having to go after all the sites hosting the objectionable content. The concept is that information that can't be found is almost the same as information that does not exist at all.

Because a few search engines dominate the market, they become an easy leverage point for achieving broad objectives. Countries like China and Iran have long understood the power of censoring the search engines to block access to information they don't have easy reach to censor directly.

Surveillance of Skype Messages Found in China - NYTimes.com

Surveillance of Skype Messages Found in China - NYTimes.com Activists at Citizen Lab, a research group at the University of Toronto, have discovered a massive program of surveillance against Skype in China. Specifically the Chinese are monitoring instant message traffic on Tom-Skype, a joint venture between eBay (the owner of Skype) and a Chinese wireless operator.

It looks like all of the text messages passing through the service are scanned for key words of interest to the Chinese government. This program captures both messages within the Tom-Skype network and between that network and the rest of the Skype network.

This is yet another compelling argument for using strong encryption to prevent interception of message content. People in China can avoid this surveillance by using the non-chinese version of Skype, and using a VPN to get the communications safely out past the Chinese scanners.

Chinese Bloggers Scale The Great Firewall In Riots Aftermath - WSJ.com

Chinese Bloggers Scale The Great Firewall In Riots Aftermath - WSJ.com In a triumph of low tech, Chinese bloggers are evading the Chinese national censorship system by simply converting their posts to read right to left rather than left to right.Clearly this is only a short term solution, and the government will adapt quickly, but it shows again how brittle these censorship systems are. 

China Net Censorship during the Olympics

China won't guarantee Web freedom over OlympicsHere is an interesting article on Internet censorship during the Olympics. Fortunately for visitors, it is easy to set up secure communication links back to the US before going over. VPN links back to a corporate headquarters outside of China can be a very effective conduit around the censorship. While Anonymizer's commercial solutions are blocked in China, our censorship circumvention technologies are very effective within the country.  

Chinese DOS Attack on CNN called off

CNN to go dark 19 April 2008 1200 GMT according to Chinese Hackers | IntelFusionIn case anyone thinks cyber warfare is a myth, this is more evidence of its reality. It appears that a non-governmental group of Chinese hackers were planning to take down CNN as a protest against their perceived western bias in coverage of Chinese issues. Evidently news of the plans spread too far, and it was called off.

Swiss bank in Wikileaks case abruptly abandons lawsuit | The Iconoclast - politics, law, and technology - CNET News.comIn a follow up to the earlier story, it seems that the judge finally realized the implications of his actions to free speech, and the fact that his injunction was almost completely ineffective. This is a really good thing. If the ruling had stood under appeal and become precedent, it would have significantly changed the Internet landscape.

Finnish government blacklists 'free speech' site.

Finnish government blacklists 'free speech' site | The Iconoclast - politics, law, and technology - CNET News.comHere is another Declan article that deserves more attention. In this case the Finnish government is censoring a website for publishing a list of websites he discovered to be on a secret censorship black list compiled by the Finnish government. Censoring someone for trying to speak out about censorship is almost always a bad idea. As one might expect, free speech advocates around the world have mirrored the black list so many times and in so many places, it will be just about impossible for the Finnish government to contain the spread.
