Storm botnet
By 2007, Lovet notes cybercriminals already had lucrative business models in place. Before then, however, botnets were fairly fragile: By neutralizing its unique Control Center, a botnet could be completely neutralized, because the bots no longer had anyone to report to or take commands from.
By implementing a peer-to-peer architecture, Storm became the first botnet with decentralized command.
At the peak of the epidemic, Storm had infected between 1 and 50 million systems and accounted for 8 percent of all malware running in the world.
