This should be standard practice in network security. Seriously who leaves all thier stuff as default? Well usually not very tech savy people but if your on this forum i'm certain you'll know how to acess the router's interface and do that. So what's the excuse. And you could do it for family and friends like i do. I also turn tr069 off too. Grab your details and configure it your self. If u need tr069 a router reset tends to enable it anyways.So Virgin media advising customers to change details as apparently hackers are able to access the SuperHub2....
