What is a Distributed Denial of Service (DDoS) Attack?
A Distributed Denial of Service (DDoS) attack is an attempt to make an online website/service unavailable to its intended users by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, to disrupt their business operations and causing huge losses in revenue.
What DDos Attackers do
Grow Botnet Capacity
Attackers spread malicious software through emails, websites & social media to infect computers, IoT devices & smartphones to build networks known as 'botnets'. These infected devices can be controlled remotely, without their owners' knowledge, and used like an army to launch an attack against any target. Some botnet networks are millions of devices strong.
Botnet Black Market
There are online black marketplaces where people/organizations buy and sell botnets or individual DDoS attacks. Anyone can pay a nominal fee to silence any websites they like with or disrupt an organization’s online operations. A week-long DDoS attack, capable of taking a small organizations' website/web applications down can cost as low as $150 based on third party reports.
Launching DDos Attacks
Botnets can generate huge floods of traffic to overwhelm a target. These floods can be generated in multiple ways, such as sending more connection requests than a server can handle, or having the botnets to send the victim huge amounts of random data to use up the target’s bandwidth
Impact of DDos Attacks
DDoS attacks can happen anytime from anywhere in the world and its nearer to you than you think. Based on a third party report, there are about 2,000 DDoS attacks that happen on a daily basis.
