[infosecinstitute] ICMP Attacks

ICMP stands for Internet Control Message Protocol and is the most used protocol in networking technology. A connectionless protocol, ICMP does not use any port number and works in the network layer. ICMP is commonly used for diagnostic purposes, error reporting or querying any server, and right now attackers are using ICMP to send payloads, which we will discuss here. The popular ping command will use ICMP. There are lot of security issues of ICMP messages that we really need to look at.
