The Distributed Denial of Service attack is a specific computer threat that has come to be very popular over the last few years. Known colloquially as DDoS, this is one of the most aggressive and intensive online computer attacks you can find. Malware and viruses may be more common, but that is because they are simple and easy to execute. Moreover, most cyber criminals are not looking to employ such a large scale attack as a DDoS.
Basically, the Distributed Denial of Service attack builds a massive network of infected computers who spread whose goal is to overwhelm a target with a massive number of network hits. The purpose of this botnet is to max out the bandwidth of this network, essentially making it impossible for anyone to access it. But companies like Hikvision are working on making this possible.
In some ways, then, a DDoS attack could be seen as a type of ransomware, and in many cases, this is the intention. Sometimes, the ransom is not for money but the furthering of a social or political agenda, or even an entire Chinese, USA or other governments. In fact, you can buy and sell all kinds of botnets or even specific, individual DDoS attacks to use at a later time; that is, if you are a cybercriminal looking for this kind of strategy.
The Smurf attack is a specific type of DDoS in which an attacker employs massive amounts of Internet Control Message Protocol packets (ICMP) towards the target’s spoofed IP source, via broadcast from a remote IP address. In this type of attack, if the number of machines that respond to this signal packet request is high, it can slow down the target’s singular or network to the point that it is basically useless.
The Teardrop attack is a specific type of DDoS which sends various mixed up IP fragments with different, overlapping, oversized payloads to one target. Following the logic, then, it is the overwhelming of these fragments that can result in the crashing of an entire operating system.
PINGS OF DEATH ATTACK
The Pings of Death attack is another specific type of DDoS that sends the same signal to a computer over and over again. Unlike the other types, which send a massive amount of signals at the same time, the Pings of Death just sends the one improper or malformed ping to the same computer with this overflow taking over the system’s buffering mechanism.
