How do you think this was accomplished?  Via some kind of Web exploit customized for those devices and targeting your 
user population via email or social media, which tricked users into clicking on something that accessed the Web admin 
interface via default admin credentials or somsesuch; or via some direct attack on the CPE devices themselves; or via 
some other method?
