The internet is heavily resilient to damage. Attacks may cause some users to lose connectivity or disrupt the path between two sets of users, but, on the whole, the network survives. But what if there were a way to “kill” the Internet, even temporarily? Over the last decade, we’ve seen a number of major distributed denial-of-service (DDoS) attacks against the DNS root – a potential Internet choke point – as an example of attempts to disrupt the global flow of IP traffic. And every couple of years, a new vulnerability is found in a core Internet protocol. Recently, a new such attack was devised. Security researchers from the University of Minnesota came up with what they called Coordinated Cross Plane Session Termination (CXPST), a form of DDoS attack designed to cause wide-scale disruption to Internet traffic. The researchers designed an attack that could be classified as an “Internet Killer” using a botnet of only 250,000 nodes and overcoming traditional defenses. While the attack was successfully simulated in the lab, the fact that you are able to read these words online today suggests that it has yet to be seen in the wild.So does this spell doom for the Internet? Probably not. It’s still a largely theoretical threat, and there is also the question of potential attackers: who would do such a thing?
When reading alot about cyberattacks with DDoS (Botnets) I discovered that in nowadays its the biggest threat for internet users and even the internet itself, so i choose the topic because i believe it is relevent to everyone and it perfectly fits to the IT security topic.
