CAPEC-325: TCP Congestion Control Flag (ECN) Probe
This OS fingerprinting probe checks to see if the remote host supports explicit congestion notification (ECN) messaging. ECN messaging was designed to allow routers to notify a remote host when signal congestion problems are occurring. Explicit Congestion Notification messaging is defined by RFC 3168. Different operating systems and versions may or may not implement ECN notifications, or may respond uniquely to particular ECN flag types.

Overview
CAPEC-325 (TCP Congestion Control Flag (ECN) Probe) is a detailed-level attack pattern catalogued by MITRE in the Common Attack Pattern Enumeration and Classification (CAPEC). It describes a recurring method attackers use to exploit software weaknesses.
What the attacker needs
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.
Resources required
- A tool capable of sending and receiving packets from a remote system.
