			<content:encoded><![CDATA[<p>This morning Twitter was a fire with people talking about the news that O2 are sending the phone number of a user in the HTTP request headers when browsing from a phone.</p>
<p>Some people were upset about this and others were complaining that this is &#8220;No big deal&#8221;.</p>
<p>On it&#8217;s own it might not be but O2 has several &#8216;Self Service&#8217; portals on it&#8217;s website which can be used to gather information about a user.</p>
<p>Some items require two factor authentication but once a SMS has been sent an attacker could call and simply ask for the code.</p>
<p><strong>Are they prepay or Contract?</strong><br />
URL: https://registration.o2.co.uk/o2/webtopup/mobiledetailssubmit.do<br />
POST: topUpNumber_req=xxxxxxxxxxx&#038;cardCategoryId_req=2&#038;topupamount_req=10&#038;continue_88=Continue</p>
<p><strong>Have they registered for MyO2 yet?</strong><br />
URL: https://registration.o2.co.uk/Reclaim/ReclaimUserNameAndPassword<br />
POST: Continue=Continue&#038;actionname=CustomerSearchMsisdn&#038;remindMsisdn=xxxxxxxxxx</p>
<p><strong>Cause a &#8216;Denial of Service&#8217; Against Registering for MyO2 by exhausting verification tokens</strong><br />
URL: https://registration.o2.co.uk/Register/PreRegister<br />
POST: &#8220;msisdn=xxxxxx&#038;Continue=continue&#8221;</p>
<p><strong>Are they signed up to O2 Priority</strong><br />
URL: http://www.o2priority.co.uk/Register<br />
POST: ReturnUrl=http%3A%2F%2Fwww.o2priority.co.uk%2Fmoments&#038;JavascriptEnabled=true&#038;AccountManagementUsage=Register&#038;AccountManagementStep=EnterMobileNumber&#038;CoreMetrics.TertiaryTag=Register%20-%20Step%201&#038;CoreMetrics.SecondaryTag=Account&#038;Mpn=xxxxxxxxxxx&#038;butRegisterEnterMobileNumber=Get%20code&#038;X-Requested-With=XMLHttpRequest</p>
<p><strong>Request PUK Code:</strong><br />
URL: http://www.o2.co.uk/apps/getPUK/getPUKService<br />
POST: MPN=xxxxxxxx&#038;viewmode=getPuk</p>
<p><strong>Start the Swap My SIM Process</strong><br />
URL: http://swapmysim.o2.co.uk/validatempn<br />
POST: msisdn=xxxxxxx</p>
<p><strong>Give them &#8216;Double Data&#8217; on mobile broadband</strong><br />
URL: https://mobilebroadbandaccess.o2.co.uk/services/login<br />
POST: mpn=xxxxxxxxx&#038;submit=Let%27s+Go</p>
<p>One thing I haven&#8217;t tried is tethering to an O2 phone and manipulating the x-up-calling-line-id header and hitting http://wap.o2.co.uk/myo2account/ to see if I get somebody else&#8217; details.</p>
<h1>I ONLY USED MY O2 PHONE NUMBER FOR THESE TESTS. THERE IS PROBABLY LOTS OF LEGISLATION THAT WOULD APPLY TO ADDING OTHER PEOPLES PHONE NUMBERS INTO THESE REQUESTS</h1>
<p><a href="https://twitter.com/#!/OllieParsley/status/162155802977771521">@OllieParsley</a> has found a temporary workaround;<br />
<strong>Change your APN settings to mobile.o2.co.uk and username o2web</strong></p>

			<content:encoded><![CDATA[<p>Someone asked me if I could pull some info about the Managed Hosting sector using <a href="http://datasift.com">DataSift</a> so after crafting the CSDL for the query I recorded 24 hours of tweets &#038; Facebook posts and managed to gather some insights.</p>
<p>Most of these facts are not surprising; for example people are still bleating on about &#8216;cloud&#8217; as if it were something new and the gender disparity is huge. With that said there are some interesting facts such as the overall sentiment was a meagre 0.18 out of 100 with the lowest and highest sentiment of -20 and +8 respectively. </p>
<p>Additionally it would appear that those discussing managed hosting are not really making an impact in social media circles as out of 66,363 interactions over 24 hours the highest Klout score was only 18.</p>
<p>I tried putting some of this data <em>(and other meta data such as top avatars, most retweeted etc)</em> into some form of infographic, I&#8217;m not a UX person or an artist so if you don&#8217;t like it / it&#8217;s an abominable crime against infographics you have been warned;</p>

			<content:encoded><![CDATA[<p>With the launch of <a href="http://www.Android-Zenoss.info">Android-Zenoss.info </a> earlier in the month the Beta testing period started. This morning the new version of <a href="https://market.android.com/details?id=net.networksaremadeofstring.rhybudd">Rhybudd &#8211; Zenoss for Android</a> was published and can be downloaded from the <a href="https://market.android.com/details?id=net.networksaremadeofstring.rhybudd">market</a>.</p>
<p>The new version required a total overhaul of the UI, a new home screen, caching to allow &#8216;instant&#8217; access, widgets, improved background polling and many other improvements such as;</p>
<ul>
<li>Past 8 hours events count bar graph widget</li>
<li>Current Zenoss Event count widget</li>
<li>SSL support</li>
<li>Dock mode</li>
<li>Instant access caching</li>
<li>Move to SD support</li>
<li>Zenoss Event log management</li>
<li>Online help</li>
<li>Searching (including voice search)</li>
</ul>
<p>The app should feel a lot more polished as it makes far better use of UI and layout hints and should be far more responsive in normal conditions and will cope better than before in less than ideal conditions <em>(laggy or no network etc)</em>.</p>

			<content:encoded><![CDATA[<p>At <a href="http://DataSift.com">DataSift</a> we in the Operations team rely heavily on Zenoss to monitor and alert us to problems or issues with the platform.</p>
<p>As an avid Android user and developer I took the opportunity to make use of the <a href="http://community.zenoss.org/community/documentation/official_documentation/api">Zenoss 3.1 JSON API </a> and write an Android app that&#8217;ll allow Operations teams who use Zenoss to interact with their installations using a native app rather than via the web interface on the normal browser.</p>
<p>The application is open source: <a href="https://github.com/NetworksAreMadeOfString/Rhybudd">https://github.com/NetworksAreMadeOfString/Rhybudd</a> so people can compile it themselves to make sure that their credentials stay safe or to branch the project and help me out. </p>
<p>The name Rhybudd is Welsh for &#8216;Caution&#8217; or &#8216;Warning&#8217;.</p>
<p>The App is available for download <a href="https://market.android.com/details?id=net.networksaremadeofstring.rhybudd">here</a>.<br />
<a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2011/09/feature_graphic.png"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2011/09/feature_graphic-300x146.png" alt="" title="feature_graphic" width="300" height="146" class="aligncenter size-medium wp-image-764" /></a></p>
<p>There are still a lot of features missing but I hope to get them finished and pushed live soon!</p>

			<content:encoded><![CDATA[<p>Our story begins, as these stories often do, with a <a href="http://news.bbc.co.uk/1/hi/uk_politics/election_2010/8661964.stm">young up-and-coming politician</a>.

<p><strong>Original from the movie:</strong><br />
Our story begins, as these stories often do, with a young up-and-coming politician. He&#8217;s a deeply religious man and a member of the conservative party. He&#8217;s completely single-minded and has no regard for the political process. The more power he attains, the more obvious his zealotry and the more aggressive his supporters become. Eventually, his party launches a special project in the name of national security. At first, it&#8217;s believed to be a search for biological weapons and is pursued without regard to its cost. However, the true goal of this project is power. Complete and total hegemonic domination. The project, however, ends violently. But the efforts of those involved are not in vain, for a new ability to wage war is born from the blood of the victims. Imagine a virus, the most terrifying virus you can, and then imagine that you and you alone have the cure. But if your ultimate goal is power, how best to use such a weapon?</p>
<p>It is at this point in our story that along comes a spider: He is a man seemingly without a conscience for whom the ends always justify the means, and it is he who suggests that their target should not be an enemy of the country, but rather the country itself. Three targets are chosen to maximize the effect of the attack: a school, a tube station, and a water treatment plant. Several hundred die within the first few weeks.</p>
<p>Fueled by the media, fear and panic spread quickly, fracturing and dividing the country until at last the true goal comes into view. Before the Saint Mary&#8217;s crisis, no one would have predicted the results of the election that year, no one. And then not long after the election, lo and behold, a miracle! Some believed it was the work of God Himself, but it was a pharmaceutical company controlled by certain party members that made them all obscenely rich. A year later, several extremists are tried, found guilty and executed while a memorial is built to canonize their victims. But the end result, the true genius of the plan, was the fear. Fear became the ultimate tool of this government, and through it our politician was ultimately appointed to the newly created position of High Chancellor.</p>
<p>The rest, as they say, is history.</p>

			<content:encoded><![CDATA[<p>Today [03/04/11] I attempted to upload a new app to the Android Market but received a 404. Bemused by this I started to dig a little bit&#8230;</p>
<p>Visiting https://market.android.com/publish usually redirects via a 302 to https://market.android.com/publish/Home but this returns a 404. I attempted to add an additional /home to the URL and then the page partially loaded;<br />

<p>Pulling up Firebug we can see that the CSS and javascript resources are relative;<br />

&lt;script language="javascript" type="text/javascript" src="gwt/com.google.wireless.android.vending.developer.HomeMod.nocache.js"></script><br />

<p>Adding ../ via Firebug allowed the CSS and Javascript to load;<br />

<p>Using a proxy of evil and some browser trickery I managed to get the site to fully load but loading the app list failed 90% of the time;<br />

<p>This could be due to the POST https://market.android.com/publish/editapp receiving a 500 error.</p>

			<content:encoded><![CDATA[<p>I recently secured a bargain on Ebay getting a Cisco 5505 Advanced Security Appliance for only £200 which a fry cry from their prices back in late 2008 (~£600) so instantly set about increasing the security of my IPv6 LAN.</p>
<p>Most Networks consist of a LAN and a WAN segment, unfortunately due to my previous IPv6 work and the inherant nature of IPv6 the LAN also has public Global Unicast addresses secured via rather crude RRAS filters. To increase the security of the LAN I need a firewall with seperate IPv4 and a IPv6 interfaces and a dual stack LAN interface.<br />
<a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2011/03/IPv6_Network_Draft_1.png"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2011/03/IPv6_Network_Draft_1-1024x525.png" alt="" title="IPv6_Network_Draft_1" width="512" height="262" class="aligncenter size-large wp-image-684" /></a></p>
<p><code><br />

</code></p>
<p>To ensure that hosts on the LAN can reach the outside world the IPv6 network needs a route and the IPv4 network needs NAT:<br />
<code><br />
ipv6 route IPv6_WAN ::/0 2a01:<strong>XXX</strong>:18e:2::1<br />
global (IPv4_WAN) 1 interface<br />
nat (DualStack_Internal) 1 172.16.0.0 255.255.255.192<br />
route IPv4_WAN 0.0.0.0 0.0.0.0 78.<strong>XXX</strong>.<strong>XXX</strong>.1 2<br />
</code></p>
<p>I&#8217;ve allocated Global Unicast addresses to the interfaces but this may not neccessarily be required as &#8220;Link-Local&#8221; addresses next hop addresses when routing but the output is as follows;<br />
<code><br />

</code></p>
<p>With Router Advertisements enabled the IPv6 enabled hosts on the LAN had already acquired an IPv6 address and were already utilising the link;<br />
<code><br />
  Traffic Statistics for "IPv6_WAN":<br />
        27944 packets input, 28710029 bytes<br />
        14333 packets output, 1017380 bytes<br />

      5 minute output rate 0 pkts/sec,  0 bytes/sec<br />
      5 minute drop rate, 0 pkts/sec<br />
</code></p>
<p>On a side note it looks like Google has moved http://ipv6.google.com away from the address it was when I was doing this testing last year from <a href="http://[2001:4860:0:1001::68]">2001:4860:0:1001::68</a> to <a href="http://[2a00:1450:8002::67]">2a00:1450:8002::67</a>.</p>

			<content:encoded><![CDATA[<p>I&#8217;m currently experimenting with embedded systems for use as Airsoft Props <em>(think Capture the Flag, Defuse the IED etc)</em> and after starting off with an Atom mini-itx board (with SSD IDE chip) <em>(£450 prototype)</em> to an ARM based SBC <em>(£325 prototype)</em> I&#8217;ve settled on the Stalker from Seeduino which has an RTC, zigbee chip support, lots of DIO, MicroSD support and more. Best of all the prototypes are now down to around £75 a throw <em>(84% saving!)</em>.</p>
<p>Unfortunately this saving comes at a cost of a lack of native serial / USB support for writing to the onboard chip. This is easily achievable with a USB to Serial TTL device which is great however upon delivery I had two devices with female 0.1&#8243; headers. The picture below shows the pin outs needed to get the two working;<br />
<a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/10/seeduino_to_ftdi.jpg"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/10/seeduino_to_ftdi.jpg" alt="" title="seeduino_to_ftdi" width="566" height="375" class="aligncenter size-full wp-image-661" /></a><br />

N/A       DTR<br />
Blue      GND<br />
Yellow   RX<br />
Orange  TX<br />
Purple    5v<br />
</code></p>
<p>Coupling the Stalker with various addons such as Zigbee transmitters and RFID chips allows the creation of a varied array of props for Airsoft Skirmishing and Milsims.</p>
<p>I&#8217;m planning on using the NanoNote to do local admin or create a Zigbee / NanoNote interface for remote admin.<br />
<a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/10/i8at.jpg"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/10/i8at.jpg" alt="" title="i8at" width="640" height="383" class="aligncenter size-full wp-image-672" /></a></p>
<p>Once the devices are all finished and had their &#8216;real world&#8217; playtests I&#8217;ll post some more info.</p>

			<content:encoded><![CDATA[<p>My first dabble with IPv6 was back in late 2008 when I experimented with Dual Stack DHCP in the RC of Windows Server 2008.</p>
<p>Now that IPv6 is enabled by default in all of the OS&#8217;s I use in my home <em>(Fedora, Windows 2008 &#038; Windows 7)</em> I decided to go back and check my traffic graphs and the results surprised me.</p>
<p><a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/09/ipv6_2years.png"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/09/ipv6_2years.png" alt="" title="ipv6_2years" width="603" height="304" class="aligncenter size-full wp-image-652" /></a></p>
<p>There was a spike in Oct &#8217;08 when I was first experimenting with IPv6 and visiting as many native IPv6 sites as I could and then it tailed off as one would expect. Interestingly the traffic started to pick up again in July of 2009 and in the 2 years of having IPv6 Internet connectivity I&#8217;ve pulled over 364Gb of traffic!</p>
<p>Looking at this year on it&#8217;s own shows a pretty consistent amount of throughput;<br />
<a href="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/09/ipv6.png"><img src="http://blog.networksaremadeofstring.co.uk/wp-content/uploads/2010/09/ipv6.png" alt="" title="ipv6" width="603" height="268" class="aligncenter size-full wp-image-649" /></a></p>
<p>I&#8217;ll try and profile the traffic and work out what or who has adopted IPv6 so well that I can do so much without even realising it.</p>
