Detection and blocking of cloned mobile devices

A non-transitory computer readable medium storing a plurality of instructions which, when executed by a processor of a network, cause the processor to perform operations for blocking a cloned mobile device, the operations comprising:

• receiving a first registration from a first mobile device at a first location, wherein the first registration includes a device identifier and a phone number;
• confirming that a second registration from a second mobile device at a second location includes the device identifier and the phone number;
• calculating a first fraud score for the first mobile device and a second fraud score for the second mobile device;
• determining that the second mobile device is the cloned mobile device, wherein the determining the second mobile device is the cloned mobile device comprises determining that the second fraud score exceeds the first fraud score and that a difference between the second fraud score and the first fraud score exceeds a threshold amount;
• and
• blocking the cloned mobile device from registering on the network.
