Denial of service attacks is defined by a number of cybercrime experts as an illegal activity that results into the disruption of certain internet-based services. The services are denied to legitimate users when a given program or software hijacks the target website’s server. After the hijack, a huge amount of data packets is sent to the server which in turn gets overwhelmed and is unable to accept legitimate users.
Quite a number of techniques are associated with denial of service attack. Some of these techniques include ping floods, smurf attacks, ping of death, slow-road attacks, teardrop attacks, nuke, reflected attacks, peer-to-peer attacks R-U-Dead-Yet?, spoofed attacks, POST DoS attacks, application-layer floods, distributed DoS attacks and permanent DoS attacks.
Of the many attacks mentioned, the distributed DoS are the most common and the go-to attack of choice for many cyber criminals. They are known as distributed because the source of malicious software used doesn’t come from a single device, rather they come from a number of devices which make use of a number of internet connections that may be spread all over the world. With the different devices used and different internet connections, distributed DoS become tricky to curb with anti-DoS solutions.
If DoS wasn’t so readily available in the market today, its malicious capabilities wouldn’t have been worrying to many. Unfortunately, it is relatively easy to come by distributed DoS over the internet as long as you have the money to pay for it and know where to look. In most cases, you will find it marked as an IP stresser or IP booter.
How it works
DDoS works in such a way that the master computer or botmaster takes control over a number of robot computers also known as botnets and proceeds to bombard the target system with a flood of data traffic or data requests. Quite a number of unsuspecting computer systems may end up becoming botnets or robots unknowingly when faced with malware (MyDoom malware has quite the reputation in this regard). MyDoom works much like a ticking time bomb in that if it is not found and diffused in time, an explosion will occur! In essence, the DoS mechanism of The MyDoom malware makes use of a predetermined date and time.
Besides MyDoom, there are other ways in which an unsuspecting computer may be turned into a botnet one of which is the use of Trojans. The other way is to make use of automated exploitative tools which tools run from remote connections. When automotive exploitative tools are used, a connection is made to the target system’s network of computers which are already compromised by this time. After the botmaster has made connection with the target system’s network of computers, specific DDoS instructions are then issued to the zombie network in order to upset the normal flow of data transmission.
Botnets take on the form of products that can got online. Unfortunately, any person with malicious intent can easily lease these system disruptors in the form of an IP stresser or IP booter. IP booters and IP stressers mean exactly the same thing although they have different names. They both are capable of crippling the target website’s legitimate systems.
