Low power and Lossy Networks (LLNs ) are made up of many embedded devices with limited power, memory, and processing resources. They are interconnected by a variety of links, such as IEEE 802.15.4, Bluetooth, Low Power WiFi, wired or other low power PLC (Powerline Communication) links. The Routing protocols for these networks have security issues. This paper describes the review of various attacks in LLNs with special reference to Hatchetman attack. This attack in lossy networks happens when malicious node changes the contents of the DAO-ACK packet. It adds the address of the non-existent destination in the piggybacked source route. When the uplink node receives the packet, it finds non-existent address of the node. Now, the node starts dropping all the received packets in the network. This decreases the network throughput, causes more energy consumption and less packet delivery rate.
