receive an incoming fraud report based, at least in part, on a first fraud detection strategy; and
parse the incoming fraud report into fraud data;
a search logic configured to search a set of fraud reports to identify instances of the fraud data; and
an alert logic configured to generate an alert in response to an instance of the fraud data being identified in the set of fraud reports.
2. The system of claim 1, wherein the fraud data includes at least one of information about the assets, entities, individuals, or organizations associated with a potential fraud.
3. The system of claim 1, wherein the parse logic is further configured to filter the fraud data into categories.
4. The system of claim 3, wherein the categories are hierarchically arranged.
5. The system of claim 1, further comprising an aggregator logic configured to:
monitor a set of fraud detection strategies to identify the incoming fraud report;
retrieve the incoming fraud report; and
send the incoming fraud report to the parse logic.
6. The system of claim 1, wherein the alert logic is configured to generate the alert based, at least in part, on an alert trigger that defines a context of the fraud data.
7. The system of claim 6, wherein the context of the fraud data includes a number of instances of the fraud data occurring within a predetermined amount of time.
8. A method, comprising:
receiving a fraud report based, at least in part, on a first fraud detection strategy;
accessing previously parsed fraud data;
identifying an instance of the previously parsed fraud data in the fraud report; and
generating an alert in response to identifying the instance of the previously parsed fraud data the fraud report.
9. The method of claim 8, further comprising parsing information of the fraud report to generate new fraud data.
10. The method of claim 9, further comprising:
identifying at least one instance of the new fraud data in a subsequent fraud report; and
generating a new alert in response to identifying the instance of the new fraud data the subsequent fraud report.
11. The method of claim 8, further comprising determining whether the instance of previously parsed fraud data satisfies an alert trigger, and wherein generating the alert is based, at least in part, on satisfying the alert trigger.
12. The method of claim 11, wherein the alert trigger is a number of instances of the previously parsed fraud data occurring in the fraud report.
