The new and totally unique GSM Intercept System JBR IV
Scandec is proud to present the very best GSM Intercept Off Air system available in the world today.
It represents years of intensive development as well as exhaustive testing under operational conditions.
It has features never before seen in ANY passive, off air intercept system.
As you are about to see, our technology has made a true quantum leap.
No other system in the market offers you the totally new technical advancements we have put into JBR IV.
So if you are a potential buyer/user of this type of equipment, and probably already familiar with the various types of active as well as passive GSM intercept systems, you are about to learn about a totally new technology.
This unit represents state-of-the-art of GSM intercept, monitoring and positioning.
The JBR IV is now being introduced for the very first time, Scandec have been involved in high end technical equipment for the government segment since 1995.
KEY FEATURES
Fully passive off air intercept of GSM communications
Totally covert operation to both target phone as well as network provider
Extraction of KI code off air New feature
Automatically intercepts calls to/from target from flagged database
Will intercept calls made in another countries New feature
Standard version has 4 channels in full duplex.
Built in tracking system of targets location, with near GPS accuracy New feature
Compact – size of a flight bag. Travel anywhere with system.
Unit will intercept SMS, fax and email New feature
As you can see from the key features, the system has four totally new major advancements:
1. Will capture the secret KI code off air.
2. Will intercept and display SMS, fax, and email.
3. It has built in tracking system with near GPS accuracy. Even when the target is inside buildings.
4. It will intercept calls made in another country.
These new key features will give the operator a totally new tool.
All other GSM intercept systems, active or passive, simply will not offer the same flexibility or ease of use as the new JBR IV.
It offers the best of the features of an active system mixed with the new features of our passive unit, without the problem of transmitting signals and thereby becoming a possible target. Active systems can easily be detected and localized with suitable equipment.
Our passive unit is totally transparent to both network providers as well as criminals wanting to detect/locate these intercept systems. It is truly 100% covert in use.
General Overview of GSM Intercept
The security of the whole GSM security model is based on the secret Ki. If this key is compromised the whole account is compromised.
Once the attacker is able to retrieve the Ki, he can not only listen to the subscribers calls, but also place calls billed to the original subscriber's account because he can now impersonate the legitimate subscriber.
However the GSM network has trip wires for this: If two phones with the same ID are powered at the same time, the GSM network notices this, makes a location query for the phones, notices that the 'same' phone is in two different locations at the same time, and closes the account, thus preventing the attacker and the legitimate subscriber from placing calls But this is not relevant if the attacker is only interested in listening to the calls of the subscriber, as is assumed in this paper. In this case, the attacker can stay passive and just listen to the call, thus staying invisible to the GSM network.
The secret KI code and razbijacing it
All other passive systems need to know the targets KI before monitoring can begin. The operator can get this either by brute force reading the SIM card, (provided you get the correct PIN code) or by getting the code from the network/airtime provider.
However, many organizations would prefer not to inform other parties of their actions, and for these agencies our new feature is extremely valuable. The operator will be totally independent in acquiring the vital KI code with our new unit.
The JBR IV is the first and only unit in the world to be able to extract the 15 digit encrypted KI code off air. This can be done either by using the main unit itself, or with the small black box which comes with every JBR IV.
The process is extremely simple to perform; although mastering it is technically equally advanced. The agent must be within a suitable distance of the targets GSM phone (a one time only operation per number).
You need only to know the targets phone number, then send out a ping to the targets GSM phone. The phone will never activate or make a ring signal, as the ping takes only milliseconds to perform. However, the targets phone will reply with specific data, including the encrypted KI code.
You then need to stay in the local area a short while so as to sample the network.
This data is then decrypted, making use of our radically new hardware and special software. This process is done in real time.
The unit now knows the telephone number, IMEI and the KI code, and enters this data into the memory of the main JBR IV unit.
Whenever the operator needs to intercept the targets calls, he simply flags the relevant telephone number with the linked KI code. From that moment on the system will can intercept all incoming and outgoing calls.
SMS, Fax & Email
The system will allow the operator to read (SMS) Short Message Service sent to and from targets phone. Also faxes are fully readable, as well as email accessed by target.
As an example the operator will be able to see targets banking codes and pin numbers if he uses the cell phone for accessing his account.
Tracking of targets location
Making use of the newly designed software specially made for this application, the JBR IV will allow the operator to track the target internationally.
This is done by triangulating the location of the cell phone via the existing base stations.
In city areas, where the base stations are numerous, the typical accuracy is +- 2 meters.
In rural areas where the base stations are fewer, typical accuracy can be +- 100 to 250 meters.
So provided the operators digital mapping system is on a scale of 3000 to 5000:1, the accuracy is extremely high. Using this technology, the problems that GPS need to see clear sky is no longer an obstacle to the operator. It will display the targets location outside as well as inside buildings.
This feature alone can be of vital importance in many scenarios, adding security to the agents involved in the visual surveillance of target.
The tracking system will work internationally, so even if the target is traveling to another country the operator will see the exact location in real time.
The tracking feature is constantly running in the background of the intercept program, as long as targets phone is switched on.
Intercept calls made in another country
This new feature is a very dramatic development. It allows the operator to intercept calls made to and from the targets cell phone regardless of location. As long as the target is using his GSM network to make or receive calls the JBR IV will intercept.
This totally redefines the current GSM intercept systems, active and passive.
Normal intercept distance for these can be 300-500 meters in city areas, and up to a few kilometres in rural areas which makes the practical use very limited and demanding.
The system will allow the operator a totally new world of freedom: Being able to intercept all calls anywhere the target travels to, from a location chosen by the operator, and not vice versa. If you are already are a user of GSM intercept systems you will clearly see the great advantage provided by this exiting new technology.
