Delay tolerant network (DTN) is an evolution of mobile adhoc network (MANET). In computing, network security is the main issue as the attacks by malicious and selfish nodes are increasing on the network day by day. This paper defines an attack model in which malicious nodes (in DTN with Prophet Routing Protocol) receive the data from genuine nodes. It is done by falsifying their routing information (Delivery Predictability). Later malicious nodes spoof their identity and receive messages as destination nodes. The Legitimate messages are deleted by malicious nodes and also from the source node buffer as the source node treats the message being delivered to the final destination. Delivery Probability, Overhead Ratio, Average Latency and Average Buffer time metrics are evaluated using ONE simulator. In simulated network, 126 nodes are considered and by making only 3% nodes malicious, performance of the network is decreased by approximately 40-50%.
