2.  What is cellphone cloning?
 What is mobile cloning?
 When did cloning start?
 GSM
 CDMA
 How is a phone cloned?
 Some Methods to detect cloned phones.
 Symptoms of cloned mobile.
 How to prevent cloning.
 Conclusion.

3.  Cell Phone cloning is copying the identity of one
mobile phone to another mobile phone.
 The main purpose of Mobile cloning is making
fraudulent calls.
 The bills for the class goes to the legitimate
subscriber.
 The cloner also can also make anonymous calls

4.  Cell Phone cloning started with Motorola
“bag” phones and reached at their peak in mid
90’s.
 The Cellular Telecommunications Industry
Assoiciation(CTIA) estimates that financial
losses due to cloning fraud are around a billion
u.s.dollars.

5.  Mobile cloning is in initial stages in india
so preventive steps should be taken by network
provider and government

6.  Global System for Mobile Communication
.A cellular technology based on TDMA.
 GSM phones use a Subscriber Identity
Module(SIM) card that contains user info.
 Any GSM automatically programmed after
plugging in the SIM card.

7.  Code Division Multiple Access is a method of
transmitting simultaneously signals over shared
portion of spectrum.
 There is no SIM card in GSM.
 In India the major CDMA service providers are
Reliance and Tata Indicom.

8.  Electronic Serial Number(ESN).It is loaded when
the phone number is manufactured.
 This number cannot be tampered or changed by
the user or a subscriber.
 This is one of the essentials to be known for
cloning a mobile phone.

9.  Mobile Identification Number
 By Knowing ESN/MIN pairs cloning can be
Successfully done on any mobile phone.

10.  Cloning involves modifying or replacing the
EPROM in the phone with a new chip
 It would allow you to configure ESN via software
like PATAGONIA.
 You would also have to change MIN number too.

11.  When you had successfully changed ESN/MIN
pair, the phone was an effective clone of another
phone.

12.  Cloning is rare on the GSM ,one of the more
widely used mobile telephone communication
systems.
 However, cloning GSM Phones is achieved by
cloning the SIM card contained within , not
necessarily any of the phone’s internal data.

13.  The important information is IMSI stored in SIM
card.
 SIM card inserted to a reader
 Connect a computer and transfer the card
details.
 Use encrypted software to interpret details.

15. Duplicate detection.
Velocity trap.
Call counting

16.  The network shows the same mobile phone at
several places
 Reactions include shutting all them off so that the
real customer will contact the operator as he lost
the service

18.  The Mobile phone seems to be moving with
impossible speed or most unlikely speeds.
 For example one phone call is made at Vizag
and in another 5 minutes call is made at
Hyderabad.

20.  Both phone and network keep the track of calls
made with the phone.
 If they differ by each other the service to that
mobile is denied(denial of service).

21.  Frequent wrong calls to your phone , or hang-
ups.
 Difficulty in placing outgoing calls.
 Incoming calls constantly receiving busy signals
or wrong numbers. Unusual calls appearing on
phone bills.

22.  Blacklisting of stolen phones is one type of
mechanism to prevent unauthorized use. An
Equipment Identity Register enables network
operators to disable stolen cellular phones on
network.
 User verification using Personal Identification
Number(PIN) codes is one method for customer
protection against cellular phone fraud

23.  Tests conducted by USA found that having a PIN
code reduced fraud by more than 80%.
 Traffic Analysis detects cellular fraud by using
artificial intelligence software to detect
suspicious calling patterns , such as sudden
increase in the length of calls or a sudden
increase in number of international calls.

24.  Software also determines whether it is physically
possible for subscriber to make a call from
current location and the time of previous call

25.  Mobile cloning is in initial stages in India so
preventive steps should be taken by the network
provider.
 Though the mobile cloning has some uses in
fields like army it has many disadvantages
 Existing cellular systems have a number of
potential weakness . It is crucial that business
and staff take mobile phone security seriously.
