Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways.
What is an amplification attack? A Domain Name Server (DNS) amplification attack is a popular form of distributed denial of service (DDoS) that relies on the use of publically accessible open DNS servers to overwhelm a victim system with DNS response traffic.
What is NTP amplification attack? NTP amplification is a type of Distributed Denial of Service (DDoS) attack in which the attacker exploits publically-accessible Network Time Protocol (NTP) servers to overwhelm the targeted with User Datagram Protocol (UDP) traffic.
What is ICMP attack? An Internet Control Message Protocol (ICMP) flood DDoS attack, also known as a Ping flood attack, is a common Denial-of-Service (DoS) attack in which an attacker attempts to overwhelm a targeted device with ICMP echo-requests (pings).
Who initiates DDoS?

Can you get tracked from DDoSing?
Yes. DDoS attacks are traceable. It is a very strenuous job to find the source of the DDoS attack or the person who started the attack, but with the right procedures and use of advanced tools, a DDoS attack can be traced back to its source.

Is denial of service Phishing? How does a DDoS attack work? A DDoS attack occurs when multiple machines work together to attack one target. To execute an attack, hackers will use phishing emails and a range of other methods to install malware on remote machines. These machines will form what is known as a botnet.
