말뭉치
- A distributed denial-of-service (DDoS) attack is one of the most powerful weapons on the internet.[1]
- When you hear about a website being “brought down by hackers,” it generally means it has become a victim of a DDoS attack.[1]
- Increasingly, the millions of devices that constitute the ever-expanding Internet of Things (IoT) are being hacked and used to become part of the botnets used to deliver DDoS attacks.[1]
- The primary way a DDoS is accomplished is through a network of remotely controlled, hacked computers or bots.[1]
- A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources.[2]
- A distributed denial of service (DDoS) attack is when an attacker, or attackers, attempt to make it impossible for a service to be delivered.[3]
- Protocol or network-layer DDoS attacks send large numbers of packets to targeted network infrastructures and infrastructure management tools.[3]
- with a distributed denial of service (DDoS) attack that managed to shut down one of the leading web powerhouses of the time.[3]
- Unfortunately, thousands of Memcached servers are sitting on the open internet, and there has been a huge upsurge in their use in DDoS attacks.[3]
- Distributed Denial of Service (DDoS) attacks are now everyday occurrences.[4]
- Whether you’re a small non-profit or a huge multinational conglomerate, your online services—email, websites, anything that faces the internet—can be slowed or completely stopped by a DDoS attack.[4]
- just the number of DDoS attacks that are increasing.[4]
- As the botnets get bigger, the scale of DDoS attacks is also increasing.[4]
- A DDoS attack is launched from numerous compromised devices, often distributed globally in what is referred to as a botnet.[5]
- A UDP flood, by definition, is any DDoS attack that floods a target with User Datagram Protocol (UDP) packets.[5]
- In an HTTP flood DDoS attack, the attacker exploits seemingly-legitimate HTTP GET or POST requests to attack a web server or application.[5]

- Knowing how to stop a DDoS attack quickly could be the difference between your organization thriving and going out of business.[6]
- If you do fall victim to a DDoS attack, you are not alone.[6]
- A distributed denial of service attack (DDoS) is a special type of denial of service attack.[6]
- The volume of data launched at DDoS attack victims has also gone up significantly, largely thanks to amplification attacks such as the memcached amplification attack technique.[6]
- In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources.[7]
- During the Hong Kong anti-extradition protests in June 2019, the messaging app Telegram was subject to a DDoS attack, aimed at preventing protesters from using it to coordinate movements.[7]

- Your devices, such as home routers, can be compromised and act as a botnet for DDoS attacks.[9]
- A Layer 3 DNS Amplification is a type of DDoS attack where the attacker hides the origin of the attack from the targeted site by reflecting the attack off of a third party.[9]
- A Layer 7 HTTP Flood Attack is a type of DDoS attack made to overload specific parts of a site or server.[9]
- But preventing DDoS attacks from happening in the first is incredibly difficult because they’re fairly simple to create.[10]
- All it takes to create a DDoS attack are two devices that coordinate to send fake traffic to a server or website.[10]
- Your laptop and your phone, for example, could form their own DDoS network (sometimes referred to as a botnet, but more on that in a minute) if you or a cybercriminal programmed them to cooperate.[10]
- Botnets don’t always have to be used in a DDoS attack, nor does a DDoS have to have a botnet to work, but more often than not they go together like Bonnie and Clyde.[10]
