The cloner is also able to make effectively anonymous calls.INTRODUCTIONESN- The ESN(Electric Serial Number) is the serial number of your cellular telephone.</p> <p>The ESN is transmitted to the cell site and used to verify that you are a legitimate user of the cellular system.</p> <p>The MIN(Mobile Identification Number) is simply the phone number of the cellular telephone.CONTINUEDIMEI stands for International Mobile Equipment Identifier, this is a 10 digit universally unique number of our GSM handset.</p> <p>It is used in tracking mobile phones.IMEICDMA(Code Division Multiple Access). A method for transmitting simultaneous signals over a shared portion of the spectrum. There is no Subscriber Identity Module(SIM) card.</p> <p>CDMA use a Mobile Identification Number(MIN) card that contains user account information.</p> <p>GSM(Global System for Mobile) Communications. GSM uses a variation of Time Division Multiple Access(TDMA) and is the most widely used of the three digital wireless telephone technologies (TDMA,GSM and CDMA).GSM AND CDMAGSM digitizes and compresses data, then it sends it down a channel with two other streams of user data, each in its own time slot.</p> <p>It operates at either the 900MHz or 1,800MHz frequency band.CONTINUEDEach phone has an Electric Serial Number (ESN), Identifying the phone, as well as a Mobile Identification Number(MIN), which includes the telephone number of the phone.</p> <p>These are used to identify the subscriber.</p> <p>When placing a call, the phone transmits both the ESN and the MIN to the network.</p> <p>ESN and MIN can be received using a suitable scanner.MOBILE CLONINGThese codes would then be programmed into another phone, effectively cloning the original subscription.</p> <p>Any calls made on this cloned phone would be charged on the original customer.CONTINUED</p> <p>DUPLICATE DETECTION The network seems the same phone in several places on the same time. Reactions include shutting them all off so that the real customer will contact the operator because he lost the service he is paying so for that the clone users will switch to another clone but the real user will contact the operator.METHODS TO DETECT THE CLONED PHONES ON THE NETWORKPIN CODES, Prior to placing a call, the caller unlocks the phone by entering a PIN code and then calls as usual. After the call has been completed, the user locks the phone by entering the PIN code again. Operators may share the PIN information to enable safer roamingCONTINUEDRF(Radio Frequency)- finger printing is originally a military technology. So the network software stores and compares fingerprints for all the phones that it sees. This way, it will spot the clones with the same identity but different finger prints.CONTINUEDUSAGE PROFILING Profiles of the customers phone usage are kept, and when discrepancies are noticed, the customer is contacted.</p> <p>For example, if a customer is normally makes only local network calls but is suddenly placing calls to foreign countries for hours of airtime, it indicates a possible clone.CONTINUEDCALL COUNTING Both the phone and network keeps the track of calls made with the phone, and should they differ more than the usually allowed one call, service is denied.CONTINUEDEvery GSM phone has a 15digit electronic serial number (referred to as the IMEI)</p> <p>The important information is the IMSI, which is stored on the removable SIM card that carries all your subscribe information.CLONING GSM PHONESThe process of hacking GSM networks is simple: A SIM card is inserted into a reader.</p> <p>After it connecting to the computer using data cables, the card details were transferred into the PC.</p> <p>Then using freely available encryption software on the Net, the card details will be encrypted on to a blank smart card.</p> <p>The result: A cloned cell phone is ready for misuse.CONTINUEDFrequent wrong number phone calls to your phones or hang-ups.</p> <p>Difficulty in placing outgoing calls.</p> <p>Difficulty in retrieving voice mail messages.</p> <p>Incoming calls constantly receiving busy signals or wrong numbers. Unusual calls appearing on your phone bills.HOW TO KNOW THAT THE CELL HAS BEEN CLONED ?User verification using personal Identification number(PIN) codes is one method for customer protection against cellular phone fraud.</p> <p>Tests conducted have proved that United States found that having a PIN code reduced fraud by more than 80%.</p> <p>Traffic analysis detects cellular fraud by using artificial intelligence software.TO PREVENT CLONINGSoftware detects suspicious calling patterns, such as a sudden increase in the length of calls or sudden increase in the number of international calls.</p> <p>The software also determines whether it is physically possible for the subscriber to be making for a call from a current location, based on the location and time of the previous call.CONTINUEDBLACK LISTING of stolen phones is another mechanism to prevent unauthorized use.</p> <p>An Equipment Identity Register(EIR) enables network operators to disable stolen cellular phones on networks around the world.CONTINUEDEach year, the mobile phone industry loses millions of dollars in revenue because of the criminal actions of the persons who are able to reconfigure mobile phones so that their calls are billed to other phones owned by innocent third persons.</p> <p>Many criminals use cloned cellular telephones for illegal activities, because their calls are not billed to them, and are therefore much more difficult to trace.IMPACT OF CLONINGPreventive steps should be taken by the network provider and the Government the enactment of the legislation to prosecute crimes related to cellular phones is not viewed as a priority.</p> <p>Existing cellular systems have a number of potential weakness that were considered. It is crucial that businesses and staff take mobile phone security seriously.CONCLUSIONHTTP://wiretap.spies.com</p> <p>HTTP://www.hackinthebox.org</p> <p>HTTP://www.google.com</p> <p>HTTP://www.wikipedia.comREFERENCESTHANKING YOU</p>
