Of course, there are exceptions in which DDOS attacks were carried out by real human attackers, for example the hackers group Anonymous integrated by thousands of people worldwide used this technique very frequently due its easy implementation (it only required volunteers who shared their cause), that’s for example how Anonymous left Gaddafi’s Libyan government completely disconnected during the invasion, the Libyan state was left defenseless before thousands of attackers from worldwide.
A hacker can create a botnet and infect many computers from which botnets will launch DOS attacks, the fact many botnets are shooting simultaneously turn the DOS attack into a DDOS attack (that’s why it is called “distributed”). Botnets are automated scripts or programs which infect computers to carry out an automated task (in this case a DDOS attack). Commonly DDOS attacks are carried out by botnets. DDOS AttacksĪ Distributed Denial of Service attack (DDOS) is similar to a DOS attack but carried out from different nodes (or different attackers) simultaneously. While this attack is very easy to execute, it does not compromise the information or privacy of the target, it is not a penetrative attack and only aims to prevent access to the target.īy sending a quantity of packets the target can’t handle attackers prevent the server from serving legitimate users.ĭOS attacks are carried out from a single device, therefore it is easy to stop them by blocking the attacker IP, yet the attacker can change and even spoof (clone) the target IP address but it is not hard for firewalls to deal with such attacks, contrary to what happens with DDOS attacks. This attack consists of overloading the target with oversized packets, or a big quantity of them.
A denial of Service (DOS) attack is a very simple technique to deny accessibility to services (that’s why it is called “denial of service” attack).
