During the incident handling and response (IH&R) process, the stage of "Evidence gathering and forensics analysis" involves the collection of evidence, forensic analysis, and detailed investigation to uncover the root cause of the incident. This stage is crucial for understanding how the incident occurred, identifying the threat actors involved, the methods they used (threat vectors), and the extent of the impact. By analyzing evidence, incident responders can reconstruct the sequence of events, identify the vulnerabilities exploited, and determine the scope of the incident. This information is vital for resolving the incident effectively and taking steps to prevent future occurrences.

Netstat (network statistics) is a command-line tool that displays network connections (both incoming and outgoing), routing tables, and a number of network interface (and network protocol) statistics. It is considered a volatile evidence collecting tool because it gathers information that exists in the system's memory, which is lost upon shutdown or reboot. This makes it invaluable for collecting evidence of active connections and processes that are present at the time of the incident response but does not persistently store data that can be recovered later. This contrasts with tools like FTK Imager or ProDiscover Forensics, which are used for acquiring digital evidence in a non-volatile manner, such as disk imaging, and HashTool, which is used for validating the integrity of collected digital evidence through hashing.

When malware moves from the delivery stage to the exploitation stage in the cyber kill chain, its objective often shifts to identifying exploitable vulnerabilities within the targeted system. A port scan is a technique used to discover services that are listening on ports within a system. By scanning the system's ports, the malware can identify open ports and the services running on them, providing valuable information about potential entry points for further exploitation. This type of reconnaissance attack is aimed at gathering intelligence on the target system's network services, which can then be reported back to a command and control center for further malicious activity planning.

Port scanning is more relevant than IP range sweeps, packet sniffing, or session hijacking for identifying useful services on a system because it directly targets the discovery of accessible network services and their corresponding ports. While the other methods can also be part of the reconnaissance phase, they serve different purposes: IP range sweeps aim to identify active IP addresses, packet sniffing intercepts data packets to gather information, and session hijacking involves taking over a valid user session. In contrast, port scanning is specifically designed to enumerate services that could be exploited.

In a disassociation attack, the attacker sends disassociation frames to a wireless access point (AP) using a spoofed MAC address of a client or to the client pretending to be the AP. This forces the target to disconnect and often reconnect, causing a disruption in the wireless connectivity. Such attacks can be used to create a denial-of-service condition for the client, making the network resource unavailable. The primary objective of this attack is not to eavesdrop but to disrupt the normal operation of the wireless connection between the client and the AP.

The GPG18 and Forensic readiness planning (SPF) principles outline various guidelines to enhance an organization's readiness for forensic investigation and response. Principle 5, which suggests that organizations should adopt a scenario-based Forensic Readiness Planning approach that learns from experience gained within the business, emphasizes the importance of being prepared for a wide range of potential incidents by leveraging lessons learned from past experiences. This approach helps in continuously improving forensic readiness and response capabilities by adapting to the evolving threat landscape and organizational changes.

Network forensic tools are designed to capture, record, and analyze network traffic. Tools like Capsa Network Analyzer, Tcpdump, and Wireshark are specifically designed for this purpose, providing capabilities to capture live traffic, analyze packets, and understand network activities. Capsa Network Analyzer is a comprehensive network monitoring tool, Tcpdump is a powerful command-line packet analyzer, and Wireshark is a widely used network protocol analyzer that provides detailed information about network traffic.

Advanced NTFS Journaling Parser, on the other hand, is not a network forensic tool but a tool used for forensic analysis of NTFS file systems. It parses the NTFS journal ($LogFile), which contains a log of changes made to files on an NTFS volume. This tool is valuable for forensic analysts who are investigating the file system activities on a Windows system, such as file creation, modification, and deletion times, rather than analyzing network traffic. Therefore, it does not fit the category of a network forensic tool.

In the static data collection process, which is part of digital forensics and incident handling, the focus is on acquiring and examining digital evidence without altering the system or the data itself. This process includes evidence examination, where the data is analyzed; system preservation, where the current state of a system or data is maintained to ensure no alteration occurs; and evidence acquisition, which involves creating an exact binary copy of the digital evidence. Password protection, however, is not a part of the static data collection process. Instead, it relates to securing access to data or systems but does not directly involve the collection or preservation of static data for forensic purposes.

Public Key Infrastructure (PKI) is a framework used to manage digital certificates and public-key encryption. It enables secure electronic transfer of information for a range of network activities such as e-commerce, internet banking, and confidential email. PKI is fundamental to the management of encryption keys and digital certificates, ensuring the secure exchange of data over networks and verification of identity.

Threat correlation is a method used by incident responders to analyze and associate various indicators of compromise (IoCs) and alerts to identify genuine threats. By correlating data from multiple sources and applying intelligence to distinguish between unrelated events and coordinated attack patterns, responders can significantly reduce the rate of false-positive alerts. This enables teams to prioritize their efforts on the most critical and likely threats, thereby reducing potential risks and corporate liabilities. Effective threat correlation involves the use of sophisticated security information and event management (SIEM) systems, threat intelligence platforms, and analytical techniques to identify relationships between seemingly disparate security events and alerts.

WMIC (Windows Management Instrumentation Command-line) is a command-line tool that provides a unified interface for Windows management tasks, including the collection of system information. It allows administrators and forensic investigators to query the live system for information about running services, their process IDs, start modes, states, and statuses, among other data. The use of WMIC is particularly valuable in incident response scenarios for gathering volatile information from a system without having to install additional software, which might alter the state of the system being investigated. By executing specific WMIC commands, Clark can extract detailed information about the services running on a system at the time of the investigation, making it an essential tool for collecting volatile data in a forensically sound manner.
