India asks social network sites to manually screen all posts.

Tuesday, December 6th, 2011

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.

Privacy, logging policies, and trackrecord

Tuesday, September 27th, 2011

There has been a lot of attention recently to the arrest of an alleged LulzSec hacker after his anonymity was compromised by the anonymity service he was using, HideMyAss.com. Some articles on the event are here, here and the provider’s explanation here.

The reason this company was able to compromise the privacy of their user was that they had logs of user activity. They know what IP address is assigned to each user and can use that to attribute any activity back to the real identity of the person behind the account.

The real problem with logs is that they exist or they don’t. You can’t keep logs only for “bad users” but not for responsible “good users” because even if it was possible to identify them as such in advance, you would not find anything like agreement about who should fall in which category.

Many operators of privacy services, including myself, feel very strongly that such tools should be usable in countries like China to circumvent the censorship and surveillance there. Such actions are certainly illegal for the user, and probably for the provider. While being a UK company and only responding to UK court orders, they were “forced” to expose the identity of a person in the US who was then arrested by the FBI.

I don’t know enough about this case to debate whether or not this person is guilty or deserved to be arrested. My concern is that this case has demonstrated that anyone who can cause a UK court order to be severed against this company can expose their users. It also makes them a target for hacking, social engineering, infiltration and other attacks which could gain access to these logs without a UK court order.

As a general rule, if information exists and people want it, there is a very good chance it will escape, if only by accident.

Perhaps we should not be too surprised that this company failed to protect its users, when it has no visible privacy policy on the website, and there are no identifiable people standing behind the product and brand with their personal reputations.

I founded this company, Anonymizer.com, and I personally stand behind our services. We have clear privacy policies, we keep no logs of the surfing activities of our users, we have no way of identifying what user may have visited what website. We have an unblemished record of providing robust privacy since 1995.

As I have said in many previous posts, it all comes down to trust. If you don’t know who is providing the service, and don’t have the ability to research their history and gauge their integrity, you should not use that service.

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

Saturday, August 13th, 2011

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.

Researchers show about a dozen US ISPs redirecting search requests

Friday, August 5th, 2011

Researchers analyzing results from the ICSI Netalyzer project have found ISPs redirecting traffic bound for Yahoo! and Bing to third parties like Paxfire, Barefruit, and Golog. According to this EFF article:

Netalyzr’s measurements show that approximately a dozen US Internet Service Providers (ISPs), including DirecPC, Frontier, Hughes, and Wide Open West, deliberately and with no visible indication route thousands of users’ entire web search traffic via Paxfire’s web proxies.

This appears to be done by returning the IP address of the intercepting server rather than the true IP address when you do a DNS lookup of the server (www.yahoo.com for example). Your browser then connects to Paxfire or one of the other companies, rather than yahoo, allowing them to collect data on your activity and possibly modify the results.

There are some things you can do to protect yourself. If your connection to the website is using SSL, or if you have a VPN, your ISP can not intercept or modify your connection.

If you are running FireFox you can install the “HTTPS Everywhere” extension, which will ensure that your connection uses SSL for most of the most popular sites on the Internet.

Using Anonymizer Universal will ensure 100% of your traffic goes over an encrypted connection which will prevent this kind of interception for all websites.

I encourage all of you to visit the ICSI Netalyzer website to test your connection and your ISP for this kind of interception, and to contribute information for their research to detect this kind of strange and/or nefarious activity.
