This indicates detection of an Internet Control Message Protocol (ICMP) echo request that has possibly originated from a Windows host running CyberKit 2.2.
An ICMP echo request is used to detect whether a host in the network is active. A remote attacker may use it to gain information about hosts on a target network and use this information for attack planning.
Any unprotected system connected to the Internet is vulnerable to the attack.
An attacker can gather information about live hosts in a network prior to launching an attack.
