Comprehensive and Detailed Explanation (ECIH-aligned):

Michael’s actions reflect crime scene control, a foundational first-response principle in the ECIH forensic readiness module. Securing the area, preventing unauthorized access, and avoiding system changes preserve evidence integrity.

Option C is correct because his primary objective is to secure and evaluate the digital crime scene before evidence collection begins. ECIH stresses that scene control prevents contamination, tampering, and accidental evidence destruction.

Options A, B, and D may follow but are not the immediate objective.

Comprehensive and Detailed Explanation (ECIH-aligned):

This incident indicates credential compromise, a common cloud security issue addressed in the ECIH Cloud Incident Handling module. When credentials are suspected to be compromised, the immediate priority is to stop unauthorized access and determine the scope of misuse.

Option B is correct because resetting the compromised credentials immediately cuts off the attacker’s access. Reviewing recent access logs allows responders to validate what actions were taken, which data was accessed, and whether additional accounts were affected. ECIH emphasizes immediate credential revocation as a first-response action in identity-based cloud incidents.

Option D (enabling MFA) is a critical hardening measure but does not immediately revoke compromised credentials. Option A is a recovery step that may not stop ongoing access. Option C may be necessary later but should not delay immediate containment.

Therefore, resetting credentials and reviewing logs is the most effective first action, fully aligned with ECIH guidance.

The scenario described is characteristic of a Trojan. A Trojan is a type of malware that disguises itself as legitimate software but performs malicious actions once installed. Unlike viruses, which can replicate themselves, or worms, which can spread across networks on their own, Trojans rely on the guise of legitimacy to trick users into initiating their execution. In this case, the user believed they were downloading and installing genuine software, but the reality was that the application contained a Trojan. The malicious code executed upon installation provided unauthorized remote access to the user's computer, which could be used by an attacker to control the system, steal data, install additional malware, or carry out other malicious activities.

Trojans can come in many forms and can be used to achieve a wide range of malicious objectives, making them a versatile and dangerous type of cyber threat. The deceptive nature of Trojans, exploiting the trust users have in what appears to be legitimate software, is what makes them particularly effective and widespread.

In the described attack, where attackers pose as legitimate access points (APs) by beaconing the WLAN's SSID to lure users, the attack is known as an Evil twin AP attack. This type of attack involves setting up a rogue AP with the same SSID as a legitimate wireless access point, making it appear as an authorized network to users. Unsuspecting users may connect to this malicious AP, allowing attackers to intercept sensitive information, conduct man-in-the-middle attacks, or distribute malware. The Evil twin AP attack exploits the trust users have in known SSIDs to compromise their security.

MxToolbox is an online tool that provides various network diagnostics and email security checks, including looking up DNS and MX records, SPF records, and more. It can be used by incident handlers to prevent the organization against evolving email threats by analyzing domain health, checking blacklists, verifying email delivery issues, and more. While Email Header Analyzer is useful for analyzing specific emails for traces of phishing or spoofing, G Suite Toolbox might be specific to Google's services, and Gpg4win is more focused on email encryption. MxToolbox provides a broader set of functionalities for monitoring and troubleshooting email delivery issues and security threats, making it a versatile tool for incident handlers.

Comprehensive and Detailed Explanation (ECIH-aligned):

This incident involves adaptive malware embedded within an AI system, actively evolving its behavior. The ECIH malware incident handling methodology prioritizes containment and eradication of the threat before recovery actions. Restoring data without removing the malware risks immediate reinfection and continued manipulation.

Option B is correct because deploying the AI-security module directly targets the malware’s adaptive mechanisms, allowing responders to detect, contain, and eradicate the malicious logic within the AI environment. ECIH emphasizes using appropriate, context-aware security controls that match the technology stack involved in the incident. For AI-driven environments, specialized tools are necessary to counter threats that traditional controls may not detect.

Option A is premature and unsafe prior to eradication. Option C disrupts business operations without resolving the threat. Option D is a communication step that should follow containment and validation.

Therefore, neutralizing the evolved malware using the AI-security module is the correct primary step.

Comprehensive and Detailed Explanation (ECIH-aligned):

This scenario demonstrates manual phishing email verification, which is a foundational detection technique taught in the ECIH Email Security module. Manual verification involves human inspection of email characteristics such as sender address anomalies, mismatched URLs, unusual tone, urgency, and contextual inconsistencies.

Option D is correct because Ethan manually inspects the email by hovering over links, reviewing sender formatting, and evaluating message tone. These actions are key indicators used to identify phishing without relying on automated tools.

Option A relates to encoding analysis, which is not described. Option B involves automated network-based detection. Option C focuses on shortened URLs, which are not present here.

ECIH emphasizes that while automated defenses are important, human verification remains critical, especially for targeted phishing attacks that bypass technical controls. Therefore, Option D correctly identifies the detection approach used.

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.

Setting up a computer forensics lab involves several critical steps that need to be executed in a logical and efficient order. The correct sequence starts with planning and budgeting (2), as it is essential to understand the scope, resources, and financial commitment required for the lab. The next step involves considering the physical location and structural design (1) to ensure the lab meets operational needs and security requirements. Work area considerations (3) follow, focusing on the layout and functionality of the workspace. Human resource considerations (6) are crucial next, to ensure the lab is staffed with qualified personnel. Physical security recommendations (4) are then implemented to protect the lab and its resources. Finally, forensic lab licensing (5) ensures the lab operates within legal and regulatory frameworks.
