CAPEC-328: TCP 'RST' Flag Checksum Probe
This OS fingerprinting probe performs a checksum on any ASCII data contained within the data portion or a RST packet. Some operating systems will report a human-readable text message in the payload of a 'RST' (reset) packet when specific types of connection errors occur. RFC 1122 allows text payloads within reset packets but not all operating systems or routers implement this functionality.

Overview
CAPEC-328 (TCP 'RST' Flag Checksum 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.
