Research on Malicious Network Traffic Communication Based on Blockchain

During the communication process of malware, a large amount of malicious traffic will be generated, malicious traffic usually uses various methods to avoid traditional security protection and detection. With the development of the Internet, public blockchains (such as Bitcoin, Ethereum, etc.) are frequently exploited by attackers to build malicious traffic communication channels. Because the blockchain has the characteristics of anonymity, decentralization, immutability, and difficulty in closure, and the blockchain provides a distributed P2P networking at the bottom. This paper investigates three botnet models which employ blockchain technology to build malicious traffic communication channels. By analyzing the security threats of malicious traffic communication technology based on blockchain, this paper examines its issues and challenges, along with possible future research directions including possible countermeasures.
