ICMP is of great significance to network security. ICMP does not have an authentication mechanism. As a result, ICMP is easy to be used to attack network devices such as switches and routers. ICMP Attacks Currently, most ICMP attacks are denial of service (DoS) attacks. The most common ICMP...
ICMP can be exploited to attack computers with what is known as the “Ping of Death”, which is acommon Cyber attackthat can cause Denial of Service issues in your networks. An IP packet designed to overflow a target computer’s buffer is sent in an attempt to crash its system. Another ...
ICMP flood attack.Sometimes called aping flood attack, the goal of this attack is to overwhelm the target device with echo request packets. Each echo request packet must be processed by the target and responded to with Echo Reply messages. This sucks up all the target computer's resources, c...
In a DDoS attack, ICMP is commonly used in a few different ways: through an ICMP flood attack, a ping of death attack, or a Smurf attack. ICMP flood attack In an ICMP flood attack, the attacker tries to send so many pings that the device being targeted cannot handle all the ICMP ech...
Smurf attack:A distributed denial-of-service attack where a large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim's spoofed source IP are broadcast to a computer network using an IP broadcast address.
Confused by ICMP? Don't worry! This beginner-friendly guide demystifies the Internet Control Message Protocol with clear explanations & a helpful diagram.
ICMP flood attack: Ping of death attack A ping of death attack is when the attacker sends a ping larger than the maximum allowable size for a packet to a targeted machine, causing the machine to freeze or crash. The packet gets fragmented on the way to its target, but when the target ...

Smurf attack is a form of a DDoS attack that renders a victim’s network inoperable in a similar way, but the difference is that it does so by exploiting IP and ICMP vulnerabilities. Exploiting these vulnerabilities is what sets a Smurf attack apart, in turn increasing the potential for ...
IP fragmentation attacks is a type of cyber attack that exploits how IP packets are fragmented and reassembled to evade security controls and launch attacks. Attackers manipulate fragmented packet parameters like offsets and sizes to trigger vulnerabilities or bypass firewall rules. ...
