Bentley's botnet of around 100 computers, all located within the corporate network of Newell Rubbermaid -- makers of products such as Sharpie markers and plastic food containers -- spread like a network worm, seeking out nearby computers on the same subnet and exploiting security flaws in Windows to install themselves on other machines.
The only problem was that the bots were too good at seeking out their neighbors and ended up flooding the Rubbermaid corporate network. When that happened, according to the indictment, the "voluminous network traffic generated by this scanning has the effect of simultaneously limiting or even preventing" the infected systems from making network connections.
The victims’ computers were infected with the DollarRevenue adware program, which caused popup ads to appear almost continuously. Unfortunately for Bentley, the botnet did not appear to have spread beyond Rubbermaid's corporate network. In the end, Bentley earned less in commissions than it cost the company to restore all the infected computers.
