The orders from the commanding control servers include directions for launching an attack from bots malware to a particular target using selected attack methods. Once a computer turns into a bot, it connects to the attacker’s control circuits and it begins to accept orders from these centralised machines.

Any users tricked into running such malware will unintentionally turn their computer into a bot, and provide attackers with an access point to their computer.

Malware can spread via compromised websites, e-mail attachments, or through an organisation’s network. In order to turn a computer into a bot, attackers develop specialised malware which they spread to as many vulnerable computers as possible. The first step in launching a Distributed Denial of Service (DDoS) attack is to recruit an army of bots. Or, the attack can be launched from multiple connected devices that are distributed across the internet, in an orchestrated Distributed Denial of Service attack, or DDoS. In a DoS attack, a perpetrator can use a single Internet connection to exploit a software vulnerability or flood the target with fake requests and finally cause that the site is made unavailable and prevent it from responding to requests from the legitimate users. Also, they warn about repetitive nature of these attacks, explaining that if your company has been the target of a DDoS attack, there’s a 1 in 4 (25%) chance that you’ll be attacked again within a 3 months and greater than a 1 in 3 (36%) chance that you’ll be targeted again within a year.ĭenial of service does what its name suggests: it renders a website unavailable to users, but a successful one will hit an entire online user database. They are also the most costly cyber crimes and account for more than 55% of all annual cyber crime.Īkamai predicts that by 2020 the average DDoS attack will generate 1.5 Tbps of network traffic. First in the category are Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks. With the rising popularity of websites and web based applications has come a corresponding boom in the numbers, types, magnitudes and costs of attacks that specifically target the vulnerabilities of these systems.
