This incident involves malware embedded within third-party modifications, affecting financial data and game integrity. The ECIH malware handling framework prioritizes rapid containment to prevent further exploitation before analysis or public communication.

Option B is correct because disabling all mods immediately stops the malicious mod from continuing to operate, preventing additional data theft and financial abuse. This action contains the threat across the entire user base quickly and uniformly.

Option A focuses on detection and removal but may miss distributed instances already in use. Option C is a communication step that should follow containment. Option D delays action and allows continued exploitation.

ECIH stresses that when malware is actively impacting users at scale, containment actions that reduce attack surface globally are preferred. Disabling all mods is the fastest and safest initial containment measure, making Option B correct.

The term that describes the combination of strategies and services intended to restore data, applications, and other resources to the public cloud or dedicated service providers is "Cloud recovery." This term encompasses disaster recovery efforts focused on ensuring that an organization's digital assets can be quickly and effectively restored or moved to cloud environments in the event of data loss, system failure, or a disaster. Cloud recovery strategies are part of a broader disaster recovery and business continuity planning, ensuring minimal downtime and data loss by leveraging cloud computing's scalability and flexibility. Mitigation, analysis, and eradication are terms associated with other aspects of incident response and risk management, not specifically with the restoration of resources to cloud environments.

A TCP Xmas scan is a type of network scanning technique used by attackers to identify open ports on a target machine. The name "Xmas" comes from the set of flags that are turned on within the packet, making it 'lit up like a Christmas tree'. Specifically, the FIN, PSH, and URG flags are set, which corresponds to the hexadecimal value 0X029 in the TCP header's flags field. Wireshark, a popular network protocol analyzer, allows users to create custom filters to detect specific types of network traffic, including malicious scanning attempts. By using the filtertcp.flags==0X029, Rose can detect packets that have these specific flags set, indicating a potential TCP Xmas scan attempt.

Behavioral analysis is a technique used to detect insider threats by analyzing the behavior of employees, both individually and in group settings, to identify any actions that deviate from the norm. This method relies on monitoring and analyzing data related to user activities, access patterns, and other behaviors that could indicate malicious intent or a potential security risk from within the organization. Behavioral analysis can detect unusual access to sensitive data, abnormal data transfer activities, and other indicators of insider threats. This approach is proactive and can help in identifying potential insider threats before they result in significant harm to the organization.

The EC-Council Incident Handler (ECIH) curriculum states that during the detection and analysis phase, responders must validate the incident before taking disruptive containment actions. In suspected DoS attacks, traffic analysis is critical to confirm attack patterns such as SYN floods characterized by numerous half-open TCP connections.

Inspecting network traffic using packet captures, firewall logs, and IDS telemetry allows responders to confirm the nature of the attack, identify source IP behavior, and determine whether IP spoofing or distributed sources are involved. This ensures appropriate mitigation such as SYN cookies, rate limiting, or upstream filtering.

Option A is unrelated. Option B may disrupt business operations prematurely. Option D (rebooting) does not address the attack and may temporarily relieve symptoms without mitigation.

ECIH emphasizes evidence preservation, traffic validation, and controlled response during DoS incidents. Therefore, the first step is to inspect network traffic to confirm the attack pattern and verify source behavior.

Centralized logging and monitoring is a core best practice in cloud incident detection and response under ECIH. Cloud environments are distributed and dynamic, making visibility a major challenge.

Option C is correct because aggregating logs from multiple cloud platforms enables correlation, faster detection, and effective incident triage. ECIH emphasizes centralized visibility as essential for identifying cross-platform threats.

Options A and D are limited in scope. Option B does not address cloud-specific risks.

The ECIH incident validation phase emphasizes the importance of direct evidence when confirming unauthorized access. Log entries that show access to sensitive or restricted files provide concrete proof that an attacker successfully breached controls.

Option B is correct because access logs tied to critical resources confirm both authentication success and unauthorized activity. Failed logins or system performance issues alone do not confirm compromise.

Option A, C, and D are indirect indicators that may signal suspicious behavior but cannot independently confirm unauthorized access.

Therefore, verified log evidence is the strongest indicator, aligning with ECIH incident triage and validation principles.

Cross-Site Scripting attacks occur when untrusted input is processed and rendered by an application without proper validation or encoding. ECIH web application security guidance identifies input validation and output encoding as the most effective primary defense against XSS.

Option B is correct because sanitizing and validating all user input ensures that malicious scripts are neutralized before being stored or rendered. This addresses the root cause of XSS vulnerabilities.

Option A is a detection control, not a prevention mechanism. Option C improves system security but does not prevent application-level XSS flaws. Option D addresses abuse and DoS scenarios, not script injection.

Therefore, focusing on input validation is the most effective proactive control against XSS, as emphasized in the ECIH curriculum.

ECIH cloud incident handling guidance emphasizes that containment must be immediate and within the organization’s control. Modifying cloud security groups allows responders to restrict network access instantly, preventing further data exfiltration.

Option D is correct because it is actionable without CSP dependency and directly limits attacker movement. Option A may take time. Option B is investigative. Option C is regulatory and premature.

Containment through security group modification is therefore the most critical first step.

According to the EC-Council Incident Handler (ECIH) curriculum, the first responder’s primary responsibility upon discovering a potential cybercrime is to preserve and protect the crime scene. This includes isolating affected systems, preventing further network communication, restricting physical and logical access, and ensuring no evidence is altered or destroyed.

Sophia’s actions—isolating the system, restricting access, preventing tampering, and escalating to the IR team—align precisely with crime scene protection principles. ECIH emphasizes that improper handling during the early stages of an incident can contaminate evidence and compromise forensic investigations.

Option A (chain of custody documentation) occurs once evidence is formally collected. Option B (evidence log collection) is part of forensic acquisition. Option C (advanced forensic analysis) is performed by specialized investigators later in the response lifecycle.

Therefore, Sophia is performing the role of protecting the integrity of the crime scene as a first responder.
