Last week the complete unredacted diplomatic cables obtained by WikiLeaks last year were revealed to the world following a series of events involving WikiLeaks, the Guardian and possibly others. There has been much finger pointing regarding who is to ultimately blame for this, which is essentially pointless. The deed is done and the information is out. A couple of days later WikiLeaks, under the direction of Julian Assange, elected to update their Cablegate site with the unredacted data and provide a full mirror archive [torrent] and PostgreSQL database copy [torrent].

Already there are interesting revelations being brought to international attention by the latest data releases. There are also very valid concerns regarding the safety of intelligence sources, victims of crime and political dissidents who are identified in the cables. Amongst these have been the revelation that one or more cables identify current Australian intelligence officers, as reported in The Age and The Sydney Morning Herald.

Last Friday a statement [PDF] was made by Robert McClelland, the Australian Attorney-General, regarding this fact and confirming that the Australian Security Intelligence Organisation (ASIO), along with other agencies, were reviewing the material. Mr. McLelland reiterated that Section 92 of the Australian Security Intelligence Organisation Act 1979 (ASIO Act) makes it a crime to “publish or cause to be published in a newspaper or other publication, or by radio broadcast or television, or otherwise make public, any matter stating, or from which it could reasonably be inferred, that a person having a particular name or otherwise identified, or a person residing at a particular address, is an officer (not including the Director-General), employee or agent of the Organisation or is in any way connected with such an officer, employee or agent or, subject to subsection (1B), is a former officer (not including a former Director-General), employee or agent of the Organisation or is in any way connected with such a former officer, employee or agent.” That second part is obviously aimed at protecting the families of ASIO employees, while subsection 1B deals with exceptions where former officers have consented to their previous employment being made public.

This has led to speculation that Julian Assange could face prosecution under Section 92 of the ASIO Act. There may be the possibility of additional charges relating to officers of other Australian agencies, such as the Office of National Assessments (ONA) or the Australian Secret Intelligence Service (ASIS). In adition to the cable referred to by The Age and The Sydney Morning Herald there is at least one cable which lists the names of a number of senior ONA analysts and there may be more buried amongst the quarter of a million cables.

One of the problems facing any Australian prosecution in this matter will be whether or not charges can be laid based on the sequence of events. The initial revelations of the complete data came from a GPG encrypted file which had been available online via BitTorrent for several months and which was decrypted using a passphrase published by the Guardian. Each on its own could not reveal the information, they had to be used together to obtain the data. If charges were to be laid related to that, who would be charged? Julian Assange for creating the encrypted file? Another WikiLeaks staffer for putting it on BitTorrent? David Leigh and Luke Harding at the Guardian for publishing the decryption passphrase in WikiLeaks: Inside Jullian Assange’s War on Secrecy? John Young at Cryptome for providing the decrypted CSV file? Raymond Hill at Cablegate Search for using that data in his online database? Others?

That’s just dealing with the initial release of the data. The next question is whether or not Julian Assange or others involved with WikiLeaks can be charged for effectively republishing the data after it has already been decrypted by others? No doubt this is something which Australian Commonwealth prosecuters will consider following the reviews of the diplomatic cables being conducted by ASIO and others.

On Sunday the Attorney-General followed the national security theme with a statement [PDF] announcing a new national security awareness campaign promoting the National Security Hotline (NSH). The NSH was introduced in 2002 by the Howard Government and the initial advertising campaign in 2003 featured much derided fridge magnets for every household.

What is unclear about the latest NSH advertising campaign is whether it was already planned, whether or not it is in response to or accelerated due to the release of the unredacted cables or whether it is part of a push to turn public opinion against WikiLeaks. When the cables were being dribbled out with effort taken to redact information that could identify people at risk of violence or retaliation it was difficult for many people to take the government’s objection too seriously. The complete release last week changes that scenario completely and the publication has been condemned by the traditional media organisations, which had previously worked with WikiLeaks to redact and publish the cables. It is possible that the Attorney-General’s department views an elevation of national security in the public consciousness will make it easier for people to draw the conclusion that the cable publication and, by extension, WikiLeaks is to be condemned.

Regardless of one’s opinions of Julian Assange and WikiLeaks, either for or against, the fact is that the facility to provide a platform for the global release of sensitive material has been a major change for both national and international politics. It has shifted the concentration of power in ways which governments are not used to. They are beginning to learn a similar lesson to that of the media: that the people formerly known as the audience are able to actively engage to a greater extent than previously possible. Not only are people able to do this, but they actually do it.

As I type this there are people around the globe pouring through the released cables looking for interesting information. Some of the results are published by traditional media outlets, some are blogged about and some are included in the running commentary on Twitter or other social media networks. Most people refer to the latter as crowd-sourcing, but governments and intelligence agencies refer to it as open source intelligence. It is another example of ordinary citizens being able to level a playing field which has previously been restricted to governments, intelligence agencies, law enforcement and corporations with the budgets necessary to obtain and mine vast amounts of data. This shift is, unsurprisingly, of real concern to those organisations which have traditionally maintained a monopoly on information.

As a consequence, moves by governments around the world to attempt to limit or discourage this power shift are to be expected. Where that coincides with existing national security legislation, such as that protecting intelligence officers here in Australia, a link is able to be drawn between the power shift and a subtext of potential sedition. It’s not quite accusing anyone engaged in any aspect of the shift in power and sharing (versus control) of information of treason, but it is a manner of presenting opposition to people doing so as in the interests of national security. It is a subtle and dangerous approach to the changing nature of politics and intelligence, which could backfire. Yet it is one which will be pursued by any government seeking to maintain a concentration of power; that being, all of them.

It also won’t work, not completely, that genie is well and truly out of the bottle. The governments, intelligence agencies, law enforcement and corporations already know this; their game is now to limit anything which they see as potentially damaging. The extent of their success or failure in this will only become apparent over time; not just in relation to the various releases from WikiLeaks, but also information which will be released by other sources and organisations in the future.

There are new players in the Great Game of international politics, players who were previously viewed almost entirely as pawns. It will be very interesting to see how it plays out as the power and the rules shift.

Recent reports in The Guardian and The Independent, largely overshadowed by current events in Egypt, return to the phone hacking scandal and a renewal of the investigation into illegal activities performed by or on behalf of Rupert Murdoch’s News of the World. It is important to note that, with the exception of what apparently happened to Nick Brown’s landline, what we are talking about is not wiretapping, rather it is cracking the (poor) security of voicemail systems to access recorded messages without authorisation.

In spite of years of denials of involvement, Andy Coulson has resigned as Director of Communications for Prime Minister David Cameron. News International has fired assistant editor Ian Edmondson. While the London Metropolitan Police have finally been spurred into a new and hopefully more complete investigation. Celebrities and politicians seem intent on taking the News of the World to court for numerous breaches of their privacy.

My interest in this case is twofold.

Firstly I want to know if these activities are limited to News of the World or if they have been used by other News International or News Corporation organisations. In particular I want to know if these practices have been employed in the United States or here in Australia.

Secondly I am interested, as a professional geek, in methods of maintaining private communications. Upon the realisation that the so-called hacking was simply accessing a voicemail system, the solution to that problem was readily apparent: move the voicemail system from something under the telephone company’s control to something under one’s own control. It’s actually fairly straight forward to do with solutions available right now. Essentially it just involves forwarding missed or unanswered calls to a PABX (e.g. Asterisk) and then accessing that voicemail in a more secure manner, such as via HTTPS on any smartphone.

So I will continue to watch the case with interest and how far it does or doesn’t spread throughout the Murdoch empire. As well as seeing just how low the muckrakers will stoop for a scoop.

Recently I have noticed that a number of my friends and acquaintances have had their GMail accounts compromised. While my preferred email address is on my own server, I do have a GMail address too (actually I have a couple, but only one that is really used much) and it has not been compromised. I’ve been asked about it a little bit and I figured it best to add my thoughts here regarding best practices, along with some software recommendations.

The first and most obvious recommendation is to use a strong password, ideally with a minimum of 128 bits of entropy. The best way to achieve this is to generate a suitably strong password with KeePassX (Windows users should use KeePass). KeePassX can also be used to generate and securely store passwords for any other account or site. KeePass and KeePassX store all passwords in a database that is protected by a passphrase and 256-bit AES or Twofish encryption.

The second recommendation is to never under any circumstances use the same password for multiple accounts. Passwords for one service should not be used to link it to another service where it may be exploited by an application or plugin for the second service. This way even if one service is compromised, the potential damage is limited to that service only and won’t be able to affect other accounts on different sites.

The third recommendation is to always connect using SSL/TLS. I always recommend the Mozilla Firefox browser with the EFF’s HTTPS Everywhere plugin. The Google settings for always connecting via HTTPS and enabling either or both of IMAPS and POP3S.

The fourth recommendation is to configure a proper mail client, such as Mozilla Thunderbird, to connect with IMAP over SSL. Using a proper and robust mail client, like Thunderbird, is my preferred method of accessing email, but in the case of GMail and other primarily web based email hosting does not prevent access via the web.

The fifth recommendation is to use the Tor Browser Bundle when connecting to GMail through a public wireless point or public network (e.g. an Internet café). This software includes a modified version of Firefox that incorporates HTTPS Everywhere and will help prevent session hijacking, such as that used by the Firesheep exploit. The Tor Browser Bundle is designed to run from a USB stick and does not require any installation; simply click and run.

These fairly straight forward measures should be enough to protect any GMail account from compromise and may also be applied to other web email hosts such as Hotmail or Yahoo. Although I have not checked the extent of support for SSL/TLS connections to either of those services.

Finally, I still encourage the use of the GNU Privacy Guard for securing correspondence between parties, but that is a different matter to securing the accounts themselves.
