Investigation of Sinkhole Attacks and Network Simulation on 6LoWPAN

Sinkhole attacks have been the most dangerous threat to security in recent times. The attackers send malicious requests to Domain Name Server (DNS) that causes unavailability of services and redirects the victim to the destination designed by the malicious attacker. The malicious attacker with the help of these compromised devices forms a BOTNET and uses it for malicious purposes like ransomware, extortion, unauthorized access, fraudulent attempts, data theft, financial gains, eavesdropping, repudiation, etc. The attacker node or the sinkhole node was placed at three different locations to observe the change in count of DIO messages. The purpose of this research was to detect that at what locations can attacker gather a large amount of data. It was observed that when the attacker node was placed at the edge and along the communication links, there was a significant increase in the count of DIO messages. This means that at these points, attacker can gather a lot of information.
