Exploits using ICMP protocol Internet Control Message Protocol (shorthand, ICMP) is a part of the Internet Protocol used by network devices to send error messages to other connected hosts; for example, to indicate that a requested service is not available or a router could not be reached. But many times, this protocol is abused in transferring malicious data packets. This article discusses the vulnerabilities and security loopholes associated with such types of data transfers and potential options to prevent these security attacks.
