Claim One:
1. A computer-implemented method for detecting compromise of financial transaction accounts, the method comprising: receiving authorization data for each of a number of financial transaction accounts that are authorized for use for a financial transaction executed by a merchant device; for each of the number of financial transaction accounts, in a memory associated with a computer: storing compromise cluster analytic variables representing a pre-fraud compromise of a group of the financial transaction accounts, the pre-fraud compromise comprising information related to at least a portion of the group of the financial transaction accounts being obtained by an unauthorized third party; generating an account profile that contains predictive fraud variables to be used in conjunction with the compromise cluster analytic variables to assign a compromise account score if any of the financial transaction accounts are identified as being part of the pre-fraud compromise; generating an account transaction profile that contains a purchase history of the account, the account transaction profile further containing one or more links between financial transaction accounts that are used at a particular merchant device each during a common time period; generating a merchant device profile that contains predictive fraud variables relevant for compromise cluster generation; and generating a merchant device account transaction history profile that contains financial transaction account volume and velocity statistics at numerous time intervals, and tracking data that tracks the number of accounts that experience fraud at a later date; receiving, by the computer, reported fraud data that represents a confirmed fraudulent use of one or more of the number of financial transaction accounts; identifying, by the computer and in response to the receiving the reported fraud data, merchant devices associated with the confirmed fraudulent use; calculating, by the computer and for each merchant device of the identified merchant devices, a pre-fraud pattern; generating, by the computer and based on the pre-fraud pattern, a compromise cluster, the compromise cluster identifying suspicious financial transaction accounts, the generating the compromise cluster comprising: generating, for each suspicious financial transaction account, a compromise account score based on fraud detection variables of an associated account profile of the suspicious financial transaction account; and ranking, by the computer, each of the suspicious financial transaction accounts based on the compromise account scores; generating, by the computer, a compromise profile for the identified suspicious financial transaction accounts based on a comparison of the reported fraud data with the account profile, account transaction profile, merchant device profile, and merchant device account history profile; and denying, by the computer at authorization, a transaction associated with a first suspicious financial transaction account of the identified suspicious financial transaction accounts.
