Security expert Bruce Schneier recently talked about how someone is learning how to take down the internet. We have seen lots of companies talk about attacks on their infrastructure, breaches, hacking and stealing accounts, etc. As per the companies, it seems name of the attacks are made out to seem like probing for ways to get into networks and do harm.
It reminds me of the US’s Cold War program of flying high-altitude planes over the Soviet Union to force their air-defense systems to turn on, to map their capabilities.

From an article named Someone Is Learning How to Take Down the Internet
Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet. These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. We don't know who is doing this, but it feels like a large nation state. First, a little background. If you want to take a network off the Internet, the easiest way to do it is with a distributed denial-of-service attack (DDoS). Like the name says, this is an attack designed to prevent legitimate users from getting to the site. There are subtleties, but basically it means blasting so much data at the site that it's overwhelmed. These attacks are not new: hackers do this to sites they don't like, and criminals have done it as a method of extortion. There is an entire industry, with an arsenal of technologies, devoted to DDoS defense. But largely it's a matter of bandwidth. If the attacker has a bigger fire hose of data than the defender has, the attacker wins. Recently, some of the major companies that provide the basic infrastructure that makes the Internet work have seen an increase in DDoS attacks against them. Moreover, they have seen a certain profile of attacks. These attacks are significantly larger than the ones they're used to seeing. They last longer. They're more sophisticated. And they look like probing. One week, the attack would start at a particular level of attack and slowly ramp up before stopping. The next week, it would start at that higher point and continue. And so on, along those lines, as if the attacker were looking for the exact point of failure. The attacks are also configured in such a way as to see what the company's total defenses are. There are many different ways to launch a DDoS attack. The more attack vectors you employ simultaneously, the more different defenses the defender has to counter with. These companies are seeing more attacks using three or four different vectors. This means that the companies have to use everything they've got to defend themselves. They can't hold anything back. They're forced to demonstrate their defense capabilities for the attacker. [...] There's more. One company told me about a variety of probing attacks in addition to the DDoS attacks: testing the ability to manipulate Internet addresses and routes, seeing how long it takes the defenders to respond, and so on. Someone is extensively testing the core defensive capabilities of the companies that provide critical Internet services.
Layer 3 Communications seem to have experienced this today as their backbone had/has been having issues for a long portion of the day, bringing down with it a plethora of services from Comcast to Xbox Live.
With the expansion of IoT (Internet of Things) rapidly expanding and the severe lack of security in that spectrum things will only get worst as time goes by. To add to the security issues are users that don’t take steps to ensure their devices are secure. Routers being the most basic of things where security should be used at some basic sense come with default passwords like password or admin.
What we would like to see is a random generated 12 character default password so there is no one default account to access any two devices and allow users to change the username as well and this policy should span across all IoT devices be they netowrking equipment or the toaster in your kitchen.
This picture shows the exact place we are heading to if things don’t change security wise.
