"We have just presented data on 50,000 addresses in Japan, where the DDoS attacks came from. There were video cameras, infected with Linux malware. It was the Mirai botnet, which attacked computers across the world and carried out major DDoS attacks," Sharov said.

A DDoS attack is an attempt at making an online service unavailable by overwhelming it with traffic from multiple sources.
