The security threats are one of the common problems occurring in MANETS. In black hole attack, an attacker enters the network and show that they having a shortest path for the destination. In that way, the data is captured by the attacker. In this paper, the authors have discussed about two possible types of attacks, single black hole and multiple black hole attack in a group. They have here tried to understand the black hole attack and how to prevent the data from black hole problem having single malicious node and cooperative malicious node.
