Mirai.zushi is a Mirai-family botnet variant associated with distributed denial-of-service activity. It has been described as a relatively new branch of the Mirai ecosystem that evolved during the same year as the reported activity and had infected roughly ten thousand devices. Reported characteristics include encrypted command-and-control communications using RC4. The botnet was linked to a disruptive DDoS event affecting a high-profile livestream on X, where multiple Mirai.zushi command-and-control servers were reportedly involved alongside other infrastructure used for HTTP flooding. The observed activity indicates a focus on volumetric and application-layer denial-of-service operations rather than espionage or data theft. Based on the available facts, Mirai.zushi is best characterized as a botnet operation centered on DDoS capability within the broader Mirai malware lineage.
