To go a little into details, a major part of the USA and a bit of Europe was not able to access a because , the company providing the DNS service was taken down by a massive . huge chunk of internet Dyn DDoS attack This is the largest attack the world has ever seen. Bruce Schneier warned recently that . Source code of ‘ ’, the script used to launch the historically large on is released online. Why would anyone release such a powerful thing for free? Kerbs says, some one is planning on . someone is actively learning how to take down the internet Mirai 620 GBPS DDoS attack krebsonsecurity.com spreading the DDoS disease and selling the cure Our world economy runs on internet, its a critical piece of infrastructure. Hackers carried out an attack of this scale by infecting thousands of insecure devices left open on the internet. Using these compromised devices, they sent millions of requests per second to the servers till they melt. Now you don’t need a large network of computers to launch massive attacks. You can outsource it to these cheap, massive, omnipresent IOT devices. IOT I had a look at the source of “ ”, the script used in launching the attack. One of the interesting things I found is this. Mirai you don’t need to know programming to understand this. do you ? “ ” is basically trying out a combination of few usernames and passwords. Once any of these combinations match, it can login to the device, infect and use that device as part of its “ ” to launch the attack. It’s that simple. Now the scary part is, these devices are in millions ranging from your cameras to DVRs. Out of these at least a few thousands will match the defaults.

There is no right answer to it. But, we need to take bake steps in getting ourselves equipped with enough knowledge. First thing, be it any device, don’t bring it online if it does not needs to be. Just because there is an option don’t hook it to the internet and leave it. However secure the system is, hackers will be able to crack it down. They are a crazy bunch with lot of patience and time on their hand. If you have to bring them online, make sure they have the necessary security built into and you have followed all the necessary steps to harden it. Put pressure on the government to come up with more stringent security measures for the whole industry. Make corporations more responsible for the security aspects of the products they are manufacturing. Once a wise man said, “With Great power comes great responsibility”. We have to educate ourselves to control these so called powerful smart devices and use them wisely. Let’s take responsibility of our devices and their online presence.
