摘要: We propose Stegobot, a new generation botnet that communicates over probabilistically unobservable communication channels. It is designed to spread via social malware attacks and steal information from its victims. Unlike conventional botnets, Stegobot traffic does not introduce endpoints between bots. Instead, it based on model of covert social-network overlay - bot botmaster takes place along the edges network. Further, bots use image steganography hide presence within sharing behavior user interaction. show possible design such even with less than optimal routing mechanism as restricted flooding. analyzed real-world dataset members an online Analysis Stegobot's network throughput indicates stealthy is, also functionally powerful capable channeling fair quantities sensitive data victims at tens megabytes every month.
