1. A method for identifying a potential source of a short message service spam, the method comprising:

  • collecting, by a processor, a plurality of call detail records associated with a plurality of short message service messages, wherein a device type allocation code is included in each of the plurality of call detail records;

    extracting, by the processor, the device type allocation code from each of the plurality of call detail records, wherein the device type allocation code identifies a manufacturer of a device that is originating the plurality of short message service messages and a model type of the device;

    comparing, by the processor, the device type allocation code to a device type watch list, wherein the device type watch list includes device type allocation codes of model types that are associated with short message service spam originators;

    identifying, by the processor, the device as the potential source of the short message service spam when the device type allocation code is contained in the device type watch list; and

    blocking, by the processor, communications from an account, the account using the device that has been identified as the potential source of the short message service spam based upon the device type allocation code being contained in the device type watch list, wherein the blocking of the account is based on an entropy of time between consecutive short message service messages associated with the account.
