Network analysis and why people are so afraid of the Draft Communications Bill

This is going to be a convoluted long post, so I just decided to pick a point and start.

The Draft Communications Bill, what is it?

The Draft Communications Bill is a piece of legislation that builds upon work done by the European Union and the previous Labour administration. It is designed (as the government sees it) to maintain capability of law enforcement to access communications. It builds on a number of different pieces of legislation.

Communications Data Bill 2008 – sought to built a database of connections:

  • Websites visited
  • Telephone numbers dialled
  • Email addresses contacted

This data would be collected by internet service providers. The current government had described these plans at the time as Orwellian.

Directive 2006/24/EC of the European Parliament and of the Council of 15 March 2006 on the retention of data generated or processed in connection with the provision of publicly available electronic communications services or public communications networks and amending Directive 2002/58/EC – requires data retention to identify users and details of phone calls made and emails sent for a period between six months and two years. This information is to be  made available, on request, to law enforcement authorities to investigate and deal serious crime and terrorism.

The UK already has used non-legislative means to force 95 per cent of internet access through a filtered system, predominantly BT’s Cleanfeed which blogs blacklisted sites or pages. It has been used to filter child pornography, there were discussions about using it to block content that was deemed to glorify terrorism and has the potential to block content in a similar way to other more authoritarian nations. In a well-known case Cleanfeed had blocked a Wikipedia page on The Scorpions Virgin Killer album originally issued in 1976.

In addition, the UK government had evaluated (and rejected) internet connections being filtered for pornographic content by default – apparently due to a lack of appetite from parents for content filtering.

The Digital Economy Act of 2010 allowed sites to be blocked and allowed prosecution of consumers based on their IP address which was problematic.

So there is already a complex legal and regulatory environment that the Draft Communications Bill is likely to be part of.

In essence, the Draft Communications Bill gives the capability to build a database of everyone’s social graph. Everyone you have called, been in touch with or been in proximity to.  It requires:

  • A wide range of internet services, not just ISPs to keep a record of user data for 12 months
  • That retained data to be kept in safe and secure way; just like say credit card information or user names and passwords
  • The ability to search, filter and match data from different sources allowing a complex near-complete picture to be built up of our digital lives. Which would be of interest to hackers, criminals, private investigators or over-zealous journalists (a la the recent News International phone hacking scandals)

What the government have been keen to stress is that the process would not look at the content inside the communication. If we use the analogy of the postal service, recording all the external information on an envelope or parcel, but not peaking inside. The reason for this can be found in a successful case taken by Liberty and other organisations against the UK government in 2008. Article eight of the European Convention on Human Rights focuses on respect for private and family life, home and correspondence.

During the 1990s, the UK government had intercepted calls, faxes and electronic communication placed internationally by people in Ireland via a specially built microwave communications tower in Capenhurst. The Electronic Test Facility was uncovered by Richard Lamont in 1999 and was subsequently covered by Channel 4 news and The Independent.

Once the Electronic Test Facility came out into the public domain, the court case followed.

There are concerns about how this information can be used indiscriminately to build up a Stasi-like picture of the UK population. This is more sensitive given the controversial  black list provided to the construction industry by The Consulting Association. Latent public anxiety about commercial services like Facebook and behavioural advertising also contribute to this mindset.

Why all the power?

Modern police work and intelligence work doesn’t look like Spooks, James Bond or Starsky and Hutch. In reality, it looks more like The Wire. Investigations revolve around informants and painstaking investigation work.

A key part in this is network analysis. Understanding the structure of  relationships between participants allows them to be caught. A key part in the film The Battle of Algiers shows how French paratroopers looked to break suspects to find out the structure of their terrorist cells. If they can break them fast enough before conspirators flee, the French could roll up the terrorist infrastructure. The film’s main protagonist who instigates this policy is a portmanteau of numerous counterinsurgency specialists including Jacques Massu, Marcel Bigeard and Roger Trinquier, all of whom had been involved in the French counterinsurgency campaign from 1954 – 57 which had successfully  rolled up Algerian separatist networks in the capital Algiers.

Move forward five decades and the US counterinsurgency work in Afghanistan and Iraq puts a lot of focus on degree centrality and social network analysis as part of its efforts to dismantle al-Qaeda and other fellow travellers.

Secondly, good operational security techniques from the use of stenography or encryption of communications if implemented well can be difficult even for governments to crack. If you know the network structure, this gives you two options to gain information on the communications:

  • Look at the communications metadata: how much is going on, where is it being sent to, is the volume larger or less than normal. These can all be used as indicators that something maybe happening, changes in power within an organisation (who is giving the orders)
  • Focus resources on cracking communications that would be deemed important, for instance those to a particular number

The all-up data picture would be deemed important to provide a better picture of network analysis. When I think about myself for a minute:

I have a range of different online identities, many of which are due to the limitations of the service on which they are held or when I set them up.

I have one main UK mobile phone number, but I have had different ancillary ones:

  • Work phones
  • Temporary PAYG numbers to sell things on The Gumtree and Craigslist
  • SIMs that I have used for data only on my iPad and smartphones over the years

Now, let’s do a thought experiment, imagine a gang of drug dealers each with a set of pill boxes like old people have labelled up for each day of the week. In each section of the box would be a SIM card. They would then swap those SIMs in and out of their phones on a regular basis making their communications hard to track if you were just following one number. They could be using regularly changed secondhand mobile phones so that the IMEI number changes as well.

The SIMs could be untraceable, they could be bought and topped up for cash if they were bought outside the UK. I can go into my local convenience store here in Hong Kong and buy and top-up them up for cash or a pre-paid credit card with no one asking to see my ID.

Untraceable UK SIMs could be acquired along with bank accounts from students going home, paid off electronically, perhaps even with the debit cards attached to the accounts and the accounts topped up with ATM deposits.

But if you interrogate a database once you have one or more numbers and look for numbers that appear on a network in the same location immediately after the number you know disappears you are well on the way to tracking down more of the mobile graph of the drug dealers.

Now imagine the similar principles being applied to messaging clients, email addresses or social networking accounts in order to provide the complete network analysis of the gang of drug dealers created in the thought experiment.

How does this fit in with the people?

Under the previous Labour administration councils were given wide-ranging surveillance powers that were used to deal with incidents such as putting the wrong kind of materials in the recycling bins. This annoyed and educated British consumers on privacy. The Draft Communications Bill smacks to many as a similar kind of snoopers charter.

The internet itself, has been political and has become political. If one goes back to the roots of the early public internet, one can see the kind of libertarian themes running through it in a similar way to the back to the land efforts of the hippies which begat the modern environmental movement. This was about freedom in the same way the American pioneers could go west for physical freedom the internet opened up a new virtual frontier where one could make one’s own fate. It was no coincidence that people involved in ‘the hippy movement’ like Stewart Brand and Kevin Kelly were involved in setting the political tone of the internet.  Or that the Grateful Dead have had an online presence since 1995.

When these freedoms have been overly curtailed or threatened, internet users have struck back; sometimes unsuccessfully. The Pirate parties that sprang out of The Pirate Bay | copyright discussion have had limited political success, which has misled many to believe that the internet isn’t a political issue. What they managed to do is highlight the issue and their concerns to a wider range of people, in a similar way to how far right movements put immigration on mainstream political agendas across Europe.

It is also coupled with a decline in trust in authority, partly due to the financial crisis and the cosy relationship with the media which came to light during the phone hacking scandal.

Even The Economist realised that something was going on and called internet activism the new green. It takes mainstream political systems a while to adjust to new realities. It took at least two decades for green issues to become respectable amongst mainstream politicians and it seems to be even harder for them to grasp the abstract concepts behind the digital frontier.

The signs are all there for a change in the public’s attitude; when you have The Mail Online providing critical commentary of the Draft Communications Bill and providing recommendations of encryption software readers can use to keep their communications confidential you know that something has changed.

How does this differ from what companies can derive anyway?

This is probably where I think that things get the most interesting.

Network analysis tools are available off the shelf from the likes of Salesforce.com, IBM or SAS Institute. They have been deployed to look for fraudulent transactions, particularly on telecoms networks, and are also used to improve the quality of customer service. Many of them get inputs directly from social network such as Twitter and Facebook.

Deep packet inspection software and hardware again is available off the shelf from a number of suppliers. Companies like Narus and TopLayer Networks pioneered deep packet inspection for a wide range of reasons from surveillance to prioritising different types of network traffic. The security implications became more important (and lucrative) after 9/11; now the likes of Cisco and Huawei provide deep packet inspection products which are used for everything from securing corporate networks, preventing denial of service attacks and in the case of Phorm – behavioural advertising.

Skyhook Wireless and Google have location data that services can draw down on providing accurate information based on cell tower triangulation and a comprehensive map built-up of wi-fi hotspots.

Credit information can be obtained from numerous services, as can the electoral role. If this data is put together appropriately (which is the hard part), there is very little left of a life that would be private anyway.

Companies are trying to get to this understanding, or pretend that they are on the way there. Google’s Dashboard shows the consumer how much it infers about them and information that consumers freely give Facebook makes it an ideal platform for identity theft.

One of the most high-profile organisations to get close to this 360 view of the consumer is Delta Airlines who recently faced a backlash about it.

So what does this all mean?

We should operate on the basis that none of our electronic information is confidential. Technology that makes communication easier also diminishes privacy.  The problem isn’t the platforms per se but our behavioural adjustment to them.

CoverItLive hacked | CoverItLive 安全破

One of the digital tools that I have encouraged use of at work is CoverItLive. It consists of two elements: a dashboard and an embeddable module which is compatible with many media company content management systems to share content and engage in conversations. So live blogging of an event (we’ve used it for the UK budget announcement and social media conferences we’ve attended) or live interaction like a question-and-answer session. It looks like they have been hacked looking at this announcement this morning:

CoveritLive recently discovered that certain proprietary data files were accessed without authorization starting on or about January 7, 2012. We have not yet determined if, or to what extent, CoveritLive account information (i.e., user names, email addresses and/or passwords) was accessed. We do know, however, that no financial account information has been compromised.

Our investigation is ongoing, and, as a precautionary measure, we will implement required password resets for all active CoveritLive accounts. We plan for this process to begin Saturday January 14, 2012 at 12 AM EDT (5 AM GMT). The next time you log in after the process has begun, you will be asked to change your password before you will be allowed into your account. NOTE: we do not anticipate that you will experience a disruption in your event if you are using CoveritLive while the change is invoked.

Your password and all account passwords are encrypted as a standard CoveritLive information security practice, and we have no evidence that an unauthorized individual has actually retrieved, or is using such data. However, out of an abundance of caution we recommend that if you registered for CoveritLive using an email address and password combination that you use for other online accounts, you should immediately create unique passwords or new login credentials for those other sites and accounts.

We take this matter very seriously and will continue to work to ensure that all appropriate measures are taken to protect your personal information from unauthorized access. We also would like to take this moment to remind you of a couple of tips that should always be followed:
Do not open emails from senders you do not know. Be especially cautious of “phishing” emails, where the sender tries to trick the recipient into disclosing confidential or personal information.
Do not share personal or sensitive information via email. Legitimate companies will not attempt to collect personal information outside of a secure website.
We regret any inconvenience that this password change process may cause you. Please do not hesitate to contact us at passwords@coveritlive.com if you have any questions.

Sincerely,
CoveritLive Team

Blog spam marketing trends | 博客垃圾邮件营销的发展趋势

I was doing an upgrade on the on the WordPress software and thankfully everything went ok. Whilst I was poking around the new interface, I checked in the Akismet spam blocker statistics for the first time in ages.
akismet blog spam stats 2008 - 2011
Now this isn’t scientific, but it looks like blog spam was most prolific in 2009 and has declined since (who knows it may get a renaissance in 2012, but I hope not). Is this because there are easier pickings on social platforms like Twitter now? Has anybody else found a similar pattern?

STRATFOR breach

I got an email about 40 minutes ago announcing that STRATFOR were looking into a breach of their servers and email. I’ve always found their analysis on international issues informative and insightful which has helped in my work thinking about international projects with NGOs and in my writing here on this blog. It is one of a a number of media outlets that I pay a subscription to.

Dear Stratfor Member,

We have learned that Stratfor’s web site was hacked by an unauthorized party. As a result of this incident the operation of Stratfor’s servers and email have been suspended.

We have reason to believe that the names of our corporate subscribers have been posted on other web sites. We are diligently investigating the extent to which subscriber information may have been obtained.

Stratfor and I take this incident very seriously. Stratfor’s relationship with its members and, in particular, the confidentiality of their subscriber information, are very important to Stratfor and me. We are working closely with law enforcement in their investigation and will assist them with the identification of the individual(s) who are responsible.

Although we are still learning more and the law enforcement investigation is active and ongoing, we wanted to provide you with notice of this incident as quickly as possible. We will keep you updated regarding these matters.

Sincerely,

George Friedman

Cryptonome have more details here: complete with the obligatory Pastebin links. Twitter currently has a lively discussion on the hack.

Jargon Watch: Metz Threshold | 行话 Metz Threshold

I was listening to David Kilcullen on the C-SPAN After Words podcast, where he was interviewed about his book Counterinsurgency. One interesting concept struck me from the interview which Kilcullen called the Metz Threshold.  Kilcullen described it as the amount of time that a country’s population will tolerate their government prosecuting a war. It is based on research conducted by Dr. Steven Metz; hence the name Metz Threshold. Apparently the Metz Threshold for the US is about three years.

RIM and the UAE

Back when I was growing up in Liverpool my Dad used to tell me that ‘if something was too good to be true, it’s because it was‘. Its one of those fantastic Irish logical conundrums but it hid a basic truth: it is a lot harder to be conned if you have few expectations of anybody.

There are something about the whole RIM problems in the Middle East that don’t pass the sniff test, that it is too good to be true:

  • Look at the timing. You have a coalescence of pressure on Research In Motion from multiple countries. The United Arab Emirates is the stalking horse but there is also Saudi Arabia and India. All of which are partners with the US in the war on terror
  • Why were RIM customers in the United Arab Emirates put on such a long notice? The service is going to be turned off on October 11, 2010. That indicates that its a negotiating ploy to get leverage, or its a warning for people to get their house in order and stop doing naughty things like looking at decadent western pornography
  • RIM makes claims about its security system to its customers that experts say are doubtful. Every wireless device being sold in Russia has to be certified by the FSB, which is why the iPad 3G is currently illegal. China makes similar strong requirements to protect the security and integrity of their country. RIM sells its Blackberry devices and service in both countries. Then you have the US and the war on terror, do you honestly think that the US government would allow Blackberry devices on the market if they could be used for uncrackable terrorist-to-terrorist communication?
  • Why is RIM such a special security risk? Surely a web email connection through an SSL encrypted tunnel represents just as much of a security challenge as RIM’s secure email?

What is security anyway? Skype is considered to be one of the best most secure consumer products out there, yet its security is in question. However, if you are going to surveil someone it is much easier to get decent material if they don’t think that you are keeping an eye on them.

Its hard to know what to think. The question I am trying to think of an answer to is this: If all this was a distraction, like a street theatre act which distracts tourists so pickpockets can work them over; or a shell game where betters are deceived into following a cup with a marble hidden under it (that isn’t really there). Then what’s the real action, what are we missing that is happening before our eyes?

The life through another’s lens

In my kitchen hangs a calendar from Swift Abrasives Limited, courtesy of my Dad who works in the plant hire industry. It features nice photography and inspirational quotes from the likes of Helen Keller and Henry Ford.

The National Counterterrorism Center Calendar 2009

So what does a calendar look like for say someone involved in the war on terror. Well we don’t need to speculate about Taliban hotties any more because we can now download for free a copy of The National Counterterrorism Center’s calendar for 2009 courtesy of Wired Magazine’s Threat Level blog.

Honey, I think I’ve caught something…

If you’ve seen the recent Mac vs PC adverts you’ll have probably noticed the spot about viruses (or should that be viri?). Basically due to its popularity and fundemental flaws in the design of the Windows platform, it is under threat from thousands of different malware applications. McAfee and Symantec have issued warnings about the risk that unprotected Macs present (info here). Saying that McAfee make it nigh on impossible for a responsible consumer to purchase its Virex software and have been slow to keep up with developments in the Mac platform.

With all this in mind I came across Mark Allan’s implementation of open source anti-virus software ClamAV. Mark has put a user-friendly GUI on the software, instead of users having to hit the command line. It also monitors the users email, something that Virex failed to do. Mark does ask for donations to help him keep going (particularly for hosting and bandwidth which I think is only right and fair given the quality of the product that he’s put together).

Grabbing a Tiger by its tail

Corsaire have published a downloadable white paper on making Mac OS X 10.4 (Tiger) more secure. Whilst Tiger is the most secure OS that you can get on default settings, there is more scope to prevent less risk.

Corsaire’s white paper covers everything from setting password policies to securing the firmware and is a valuable resource for Mac users in a relatively easy-to-follow format with lots of screen grabs. After reading this there is no excuse for your Mac to be one hardcore mofo.

Kudos to Slashdot.org for pointing this one out

Do not pass go



The Economist has an interesting article about the pitfalls of modern ‘smart passports’ filled with biometric data.

They highlighted a number of deficiencies:

  • The data on the passports is unencrypted
  • Passports can be read remotely with cheap easy to acquire equipment, making it easier for terrorists to target Americans
  • Tests have shown that a significant number of passports do not work with readers
  • Biometric data creates a significant amount of false negative tests, creating a larger requirement for further screening

Clash Lyrics Unmask Big Brother State Apparatus

Interesting article on The Register. Apparently some Clash lyrics sent to a tribute band singer who had forgot his lines triggered the state security apparatus into action. Experts claim that it is proof that GCHQ monitor all SMS and voice traffic in the UK (and perhaps further afield as well).

A case of “I fought the law and the law won”?
