UK TOP FVEY Context 1.1 Internet Radio is a technology that allows audio streams, usually based on MP3 or AAC formats, to be broadcast over the Internet to clients in real- time. Details 1.2 This report documents the results of an analysis into data derived from on-line broadcasting, or ?Internet radio?. This technology allows users to broadcast audio via the internet without the restrictions traditionally associated with broadcasting. 1.1 The technology covers protocols such as ?Shoutcast?, ?lcecast? and ?Peercast?. Further details of the technology are summarised in report 4134544 1.2 The interception capability was delivered under Strategic Framework Task 4134544 by TR-CISA and was deployed at CPC in the PPF framework. 1.3 A sample of the derived SIGINT data was taken over 3-month period (August- October 2009). This sample represented 6.68 Million unique events from the accesses feeding the research system. These accesses ranged between STM1-STM64 from a range of sources. 1.4 In order to facilitate analysis, the data was tagged with the geographic location of each IP addresses from the TR-NE research prototype GEOFUSION using Slr?ip? adr?lu?log. 1.5 The data was parsed to extract client-server and server-client relationships by using the Broadcast-Server and Broadcast-Listener fields that the PPF AEG module output to the single line records. Analysis 2 Broadcast Population 2.1 There were 224,446 Unique listener IP addresses over the 3 month period covering approximately 108448 /24 subnets. 3 Geographic Distribution of Servers 3.1 Servers were geographically distributed between 1719 individual locations.

UK TOP FVEY 4 Contact Chaining Via Broadcast Events Figure 1: Interconnected Broadcast Events (Renoir) 4.1 Bulk events were visualized in Renoir. Since there is no TDI present within broadcast events, it is difficult to say how many events represent unique users. There were two distinct behaviors exhibited by users of Internet radio stations. Figure 1 shows the first type a highly connected group of Internet radio stations with listeners having multiple connections to different radio stations. Figure 2 shows the second trend within the graph. Each radio station has a set of users who are not observed connecting to any other type of Internet radio station. This observation may be an artifact of the data collection process, which is on a smaller scale than what the corporate architecture can provide. However it may provide an insight into different types of user on the Internet, the technologically savvy user who uses multiple streams of radio for entertainment or news, and a user who knows what they want to listen to.

The most common software agent was Winamp. A large number of other vendors can be seen. Notably there were nearly 2000 events from users with a PSP (Playstation Portable) and also listening via the Apple iPhone. Internet radio is likely a growth area for mobile phones and mobile devices as wireless networks increase in ubiquity and speed.

UK TOP FVEY 6 Top Radio Stations by Country 6.1 An analysis was performed on the data in order to see the most popular radio stations in a given country. The following data was obtained: Country IP Address Radio Station Iran Pakistan Russia 212.1 .226.163 M2 Radio China Egypt Radio ISMAILY ON LINE Zimbabwe United Kingdom Netherlands [Multiple hosted radio stations] Iraq Afghanistan Argentina 6.2 Different countries exhibit different behaviours at this level. The top radio stations in Russia and UK are music and entertainment based stations. The top radio station in Iraq appears to be for a Saudi based action group to free prisoners in Iraq. 6.3 It is worth noting that the top radio station in China is a French language Algerian radio station. This is possibly due to inaccuracies in the GEOFUSION dataset or an motivated and interested community in China. UK TOP FVEY

In order to observe the scale of users in the UK listening to Pakistan based radio stations, or vice versa, the data was filtered to find listeners and servers in the corresponding countries. 7.2 There were 468 events over the 3 month period corresponding to this pattern. These events were picked out and the radio station titles and descriptions were extracted. The most popular stations are shown below. Goom USA Server: Server: AWAZ 103.1 FM Server: Octane Rollin?

It is not possible to verify the content of each of these audio streams as to whether they match the description given in the URL or Title Field. 7.4 In the case of the Pakistan based broadcast server, the DNS resolves to a domestic ISP LDN. Residential customers can use a dynamic IP address service (such as to use their own connection as a static address for a Broadcast audio server. 8. Islamic Radio Stations 8.1 In order to assess the Islamic radicalization risk further, Internet broadcast titles were analyzed for the presence of keywords, Islam and Quran. 8.2 1 record contained the word ?Islam? in the ?Broadcast-Media-Genre? TLV 8.3 These stations are predominantly broadcasting recitations from the Quran, and represented 4696 events during the survey period. 3:33: lull-l I-TTI uni "Ia Figure 3: Graphs of top Islamic radio stations (Renoir) 8.4 The following radio stations were identified broadcasting this material.

8.7 8.8 8.9 8.10 8.11 UK TOP FVEY some further analysis on its listeners. The Jebril radio station is hosted on and geolocated to Dallas, USA. The radio station has a website associated with it ?The official website of Sheikh Muhammad Jebril?. It is a resource for quranic recitations and news. The following data was collated for the listeners to this station: 8 3 ran ussia re/and ia Herz vnia rance kraine udan therlands Africa Tanzania auritania zech ublic 1 omania In order to understand more about the listeners of any one particular radio station, further bulk SIGINT data from BLAZING SADDLES was used to understand any trends or behaviors. KARMA POLICE was able to correlate the Jebril radio station with the of each of its listeners. This reflected the geographical distribution seen in the broadcast media data with the majority of geolocating to Egypt and other parts of North Africa. This analysis was also performed for associated with listeners to the most popular Iraqi radio station in section X. The radio stations correlated with 123 distinct Vbulletin users, and users of other technologies such as Skype, Yahoo, MSN and Facebook. Also, it identified listeners of the radio station who use the the Maktoob blogging service. UK TOP FVEY

8.12 8.13 8.14 9.2 9.3 9.4 10. UK TOP FVEY A listener was chosen for further Internet a user located in Egypt. This user was found to have also used the following websites: Facebook. com Yahoo. com flickr. com islamwa y. com blogspot. com This profile suggests that listeners to Internet radio stations are often users of other Web 2.0 services, also that they use the web to get information from local or non- western news sources, blogs or social media. Recommendations for Future Work The single-Iine-records can be pulled through onto BLACKHOLE to feed a suitable QFD. Since the broadcast results are only events and not then they need to be correlated with the bulk TDI data that is already being processed. This might benefit Internet profiling work to understand what a user is doing on the Internet SAMUEL PEPYS). It could also be adapated into KARMA POLICE to go from a specific radio station to a list of TDls, or vice-versa. This report gives no consideration to the understanding and processing of the audio streams traversing the network. For radio stations that were private, or not accessible by the Internet, this would allow GCHQ to listen to the audio part of the protocol. A wealth of datamining techniques could be applied on small closed groups of individuals, to look for potential covert communications channels for hostile intelligence agencies running agents in allied countries, terrorist cells, or serious crime targets. An evaluation of Internet radio for future effects operations including information operations in Afghanistan or Iran could be considered as a way of getting rich audio information to a large audience of Internet connected individuals.
