7. The method according to claim 1 , wherein the method comprises replacing the first data which has been built for the target node by augmenting the first data with the new portion of the second data and storing the augmented first data in the database.
8. The method according to claim 1 , wherein the data indicative of an exchange of messages between nodes in a network linked to the target nodes is a dispersion tree showing the dispersion of messages through the network linked to the target node.
9. The method according to claim 1 , wherein the new portion of the second data indicative of the second exchange of one or more messages between nodes in the network linked to the target node includes information identifying new nodes and new messages which were not previously identified as being linked with the target node.
10. The method according to claim 1 , wherein the method comprises identifying one or more second devices which have previously made a fraud investigation request for data for the target node; and reporting, to the one or more second devices, by the circuitry, the new portion of the second data.
11. The method according to claim 1 , wherein the method further comprises formulating the new portion of the second data into a standardised data structure; and reporting the new portion of the second data in the standardised data structure.
12. The method according to claim 1 , wherein the first and second fraud investigation requests include an identifier of the first device; and wherein determining whether a fraud investigation request for the request for data for the target node has previously been received includes determining whether a fraud investigation request for data for the target node has previously been received from the first device.
13. An apparatus for reporting an exchange of messages between nodes in a network, the apparatus comprising circuitry configured to:
receive from a first device a first fraud investigation request for data for a target node, the data indicative of an exchange of messages between nodes in a network linked to the target node, the first fraud investigation request indicating that the target node is linked to potentially fraudulent activity, the target node and the nodes being separate from than the first device;
build first data indicative of a first exchange of one or more messages between nodes in the network linked to the target node, the first data being built in response to receiving the fraud investigation request;
store a record of the fraud investigation request in a database configured to store records corresponding to fraud investigation requests associated with potentially fraudulent activity in the network;
receive, from the first device, a second fraud investigation request for data for the target node, the data indicative of an exchange of messages between nodes in the network linked to the target node, the nodes being separate from the first device;
determine that a fraud investigation request for data for the target node has previously been received, the determination including querying the database to identify the record of the first fraud investigation request, the determination indicating that the target node was subject to the first fraud investigation request;
based on the determination that the first fraud investigation request was previously received,
the circuitry is further configured to:
build second data indicative of a second exchange of one or more messages between nodes in the network linked to the target node;
