![]() Further, since the requests for transactions are coming from seemingly random IP addresses all at once(the botnet), the victim may never find out the identity of the mastermind.Īlthough I won’t get into the technical details, here is an example of a fairly popular DOS tool - HULK. This can be very harmful to the website, which due to lack of resources, may shut down for a long time and even get corrupted due to overloading. When enough systems have been compromised in this way the master of the Botnet, the hacker who wants to DDOS a website may send out a message to the dormant trojans on several systems around the world, which may then indivisually begin attacking a server. A simple trojan can be sent out as a public download, and if the unsuspecting victims download it the trojan may silently settle down somewhere deep in the system and start up in the background without the user or the system ever knowing. In DDOS, Botnets are used which are just a bunch of compromised systems who have been infected with a virus or trojan. This is the reason that most DOS attacks are actually DDOS,that is Distributed-Denial of Service.ĭDOS attacks can easily bring down majority of websites. ![]() Where your internet speed might be 1Mbps, your target server might have several 100Mbps. Keeping this in mind, it is very difficult and for the most part impossible to actually bring down a website using DOS from a single computer. Most servers are built to handle a fairly large bandwidth and even the smaller ones can give maximum speeds to several hundreds of clients. Now that we’ve got a good understanding on the what DDoS is, let’s take a look at how it’s practically done. ![]()
