O The first three digits correspond to the Mobile Country Code (MCC). The IMSI is broken down into several digit groups which can be seen below: Let us use this fictitious IMSI number as an example IMSI: 621308081234567. This data is used to identify the user on the mobile network. International Mobile Subscriber Identity (IMSI): This stores a unique and encoded 15-digit number.These secret keys are critical and hence remains the data of choice for the malicious attacker. Let’s have a quick look at the sensitive files that can be found inside a SIM This data contains information about the secret keys (Cryptography) used by the phone to connect to the mobile network. Storage and file system to store sensitive system data on the SIM amongst others.Īs earlier said, a SIM card has a file system made of directories that store sensitive data.Read Only Memory (ROM) used to store the SIM program.Microprocessor which is majorly used for cryptographic processing.

I will also be giving tips on how to protect against these illegal practices.Ī SIM card is simply a smart card, which has the following In this article, I will be sharing my research work on SIM cloning while highlighting the dangers which has been prevalent and responsible for several fraudulent banking transactions.

SIM swap has been the preferred SIM fraud attack due to its ease of execution with little or no technical approach. However, fraudster have capitalized on the ease of making SIM Swap request to transfer control of the victim’s mobile number in a bid to defraud. This process legally exists to assist mobile users with damaged or stolen SIMs. SIM swap is achieved by convincing the mobile phone provider representative to switch an active SIM card to a new one. In recent times, the financial industry has experienced a surge in SIM Swap and SIM Cloning related fraud These mobile phones contain a small device called Subscriber Identity Module (SIM) which enables the transmitting and receiving of the signals to and from the network provider. The risk is also heightened now that most mobile phones serve as a device for Multifactor Authentication to mostly banking transactions. A high proportion of bank customers now have mobile phone numbers linked with their bank accounts due to the availability of several alternate banking channels (eg USSD, Mobile Banking etc.).
