CPTIA Exam Dumps : CREST Practitioner Threat Intelligence Analyst

Bob is in the Investigation phase of the forensic investigation process. This phase involves the detailed examination and analysis of the collected evidence to identify the source of the crime and the perpetrator behind the incident. It is a crucial step that follows the acquisition and preservation of evidence, where the incident responder applies various techniques and methodologies to analyze the evidentiary data. This analysis aims to uncover how the cybercrime was committed, trace the activities of the culprit, and gather actionable intelligence to support legal actions and prevent future incidents.References:The CREST materials discuss the stages of a forensic investigation, emphasizing the investigation phase as the point at which the incident responder analyzes evidence to draw conclusions about the incident's specifics.

The attack described, where multiple connection requests from different geo-locations are received by a server within a short time span leading to stress and reduced performance, is indicative of a Distributed Denial-of-Service (DDoS) attack. In a DDoS attack, the attacker floods the target's resources (such as a server) with excessive requests from multiple sources, making it difficult for the server to handle legitimate traffic, leading to degradation or outright unavailability of service. The use of multiple geo-locations for the attack sources is a common characteristic of DDoS attacks, making them harder to mitigate.References:

Netcraft is a tool that provides internet security services, including the detection of phishing and spam emails. It offers a range of services that can help organizations identify fraudulent websites and phishing activities by analyzing web content and email messages for known phishing signatures and heuristics. This makes it a useful tool for incident handlers like Francis, who is tasked with detecting phishing and spam emails for client organizations. Other options listed, such as Nessus (a vulnerability scanner), BTCrack (a Bluetooth pin and link-key cracker), and Cain and Abel (a password recovery tool), do not specialize in detecting phishing or spam emails but serve different purposes in cybersecurity.References:The Incident Handler (CREST CPTIA) curriculum includes discussions on tools and methodologies for detecting and mitigating various cyber threats, including phishing and spam, highlighting tools like Netcraft for their utility in these areas.
