The Internet Control Message Protocol (ICMP) is a protocol in the TCP/IP protocol suite used to transmit control messages between IP hosts and routers. ICMP's design characteristics make it readily usable for attacking. When an attacker sends numerous ICMP packets to the target system or network...
For an ICMP flood attack to be possible, an attacker needs to know the target's IP address. There are three categories of ICMP attacks, identified by the method of IP address retrieval: Targeted local disclosed - This type of DDoS attack requires knowledge of the target's IP address. An ...
There are so many protocols designed to trace the attacker"s address. We want to trace back attack source (i.e., "IP addresses"), we need to examine the tradeoff between different existing IP Trace back techniques. We developed a Novel protocol to trace the IP address of DDoS attack. ...
The main culprit of the attack turned out to be a teenage hacker for hire in Britain who was paid to launch this DDoS attack.Read more about this attack and how it was mitigated on the Cloudflare blog.February 2000: Mafiaboy attackIn 2000, an attacker known as “Mafiaboy” took down ...
Distributed Denial of Service (DDoS) attacks is the most challenging problems for network security. The attacker uses large number of compromised hosts to launch attack on victim. Various DDoS defense mechanisms aim at detecting and preventing the attack traffic. Source IP address spoofing is one of...
Mounted from three Chinese ISPs, the attack on thousands of Google’s IP addresses lasted for six months and peaked at a breath-taking 2.5Tbps! Damian Menscher, a Security Reliability Engineer at Google, wrote: The attacker used several networks to spoof 167 Mpps (millions of packets per sec...
Once a botnet has been established, the attacker is able to direct an attack by sending remote instructions to each bot. When a victim’s server or network is targeted by the botnet, each bot sends requests to the target’s IP address, potentially causing the server or network to become ...
The attacker spoofs the victim’s IP address as the source IP and sends ICMP echo requests (pings) to the network’s broadcast address. Routers on the network receive the ICMP echo request and flood it to all hosts per the broadcast address destination. ...
The attacker sends many ICMP echo request packets to the targeted server using multiple devices. The targeted server then sends an ICMP echo reply packet to each requesting device’s IP address as a response. The damaging effect of a Ping Flood is directly proportional to the number of requests...
Finally, analysis is the review of traffic logs to gather information about attacks, both to identify the attacker and to enhance future detection activities. When you need to compare anti-DDoS solutions, network capacity is an important factor to take into account. It is measured in Gbps (giga...
