CAPEC-332
ICMP IP 'ID' Field Error Message Probe
Description
An adversary sends a UDP datagram having an assigned value to its internet identification field (ID) to a closed port on a target to observe the manner in which this bit is echoed back in the ICMP error message. This allows the attacker to construct a fingerprint of specific OS behaviors.
Prerequisites
The ability to monitor and interact with network communications. Access to at least one host, and the privileges to interface with the network interface card.
