INTRODUCTION

Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!

Millions of cell phones users, be it GSM or CDMA, run at risk of having their phones cloned. As a cell phone user if you have been receiving exorbitantly high bills for calls that were never placed, chances are that your cell phone could be cloned. Unfortunately, there is no way the subscriber can detect cloning. Events like call dropping or anomalies in monthly bills can act as tickers.

WHAT IS CELL PHONE CLONING?

Cell phone cloning is copying the identity of one mobile telephone to another mobile telephone.

Usually this is done for the purpose of making fraudulent telephone calls. The bills for the calls go to the legitimate subscriber. The cloner is also able to make effectively anonymous calls, which attracts another group of interested users.

Cloning is the process of taking the programmed information that is stored in a legitimate mobile phone and illegally programming the identical information into another mobile phone.

TYPES OF CELLPHONES:

GSM: – Global System for Mobile Communications. A digital cellular phone technology based on TDMA GSM phones use a Subscriber Identity Module (SIM) card that contains user account information.

CDMA:- 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 unlike in GSM.Operators who provides CDMA service in India are Reliance and Tata Indicom.

CLONING CDMA CELL PHONES:

Cellular telephone thieves monitor the radio frequency spectrum and steal the cell phone pair as it is being anonymously registered with a cell site. The technology uses spread-spectrum techniques to share bands with multiple conversations.

CLONING GSM CELL PHONES:

GSM handsets, on the contrary, are safer, according to experts. Every GSM phone has a 15 digit electronic serial number (referred to as the IMEI). It is not a particularly secret bit of information and you don't need to take any care to keep it private. The important information is the IMSI, which is stored on the removable SIM card that carries all your subscriber information, roaming database and so on.

HOW IS CELL CLONING DONE?

Cloning involved modifying or replacing the EPROM in the phone with a new chip which would allow you to configure an ESN (Electronic serial number) via software.

Cloning required access to ESN and MIN pairs. ESN/MIN pairs were discovered in several ways:

Sniffing the cellular

Trashing cellular companies or cellular resellers

Hacking cellular companies or cellular resellers

HOW TO KNOW THAT THE CELL HAS BEEN CLONED? 

Frequent wrong number phone calls to your phone, or hang-ups.  

Difficulty in placing outgoing calls.

Difficulty in retrieving voice mail messages.

Incoming calls constantly receiving busy signals or wrong numbers. Unusual calls appearing on your phone bills

SOME FACTS AND FIGURES:

A Home Office report in 2002 revealed that in London around 3,000 mobile phones were stolen in one month alone which were used for cell phone cloning. 

Authorities, in the case, estimated the loss at $3,000 to $4,000 for each number used in cell phone cloning.
