212-89 Exam Dumps - EC Council Certified Incident Handler (ECIH v3)

Explanation (preparation phase):

This is classic preparation work aimed at improving detection and response speed. Valid incident handling begins before incidents occur: ensuring telemetry exists, logs are collected centrally, alerts are actionable, and roles are defined so handoffs and escalation happen quickly. Reviewing firewall and IDS/IPS logging, centralizing alerts, and aligning the response team on responsibilities directly supports monitoring readiness and operational coordination.

(A) backup hardening is about recovery resilience and integrity of backups; nothing in the scenario references backup configurations or restore testing. (B) law enforcement coordination is a procedural/legal readiness task, not what is described. (C) vulnerability scanning is proactive identification of weaknesses; again, the actions here are about log visibility and alerting, not scanning.

Network monitoring readiness (D) best fits because it includes: ensuring the right data sources are logging, time synchronization, centralized collection (SIEM/log platform), and defined responsibilities for triage and escalation. This aligns with playbook-style preparation models that emphasize roles and monitoring visibility before incidents occur .

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.

The incident involves an active cloud-based malware compromise rather than merely an operational scheduling issue. ECIH v3 cloud incident handling emphasizes using cloud-aware security capabilities to identify compromised resources, determine attack scope, detect malicious workloads or processes, and support containment and eradication. Deploying the available cloud security tool directly addresses the active threat and can help identify how the malware is spreading through the cloud environment. Monitoring flight schedules provides operational visibility but does not stop malicious activity. Halting all flights would be a severe business and safety decision that should not be taken without evidence that such disruption is necessary. Passenger notification may eventually be required depending on operational impact but does not remediate the security incident. Therefore, targeted technical investigation and containment using the cloud-specific security tool is the appropriate primary action.

================

The EC-Council Incident Handler (ECIH) curriculum explains that certain advanced mobile malware strains embed themselves as background services configured to restart automatically upon reboot. In such cases, traditional antivirus scans may fail to fully remove the threat because the malicious service remains active.

Switching the mobile device to safe mode (or emergency mode) prevents third-party applications and background services from automatically launching during startup. This isolates the malicious process and prevents it from reinitializing, allowing responders to perform forensic analysis and removal without triggering additional payload execution or data exfiltration.

ECIH emphasizes that during malware eradication, responders must prevent the malware from executing while conducting cleanup procedures. Safe mode supports controlled analysis and minimizes risk during remediation.

Option B (lost device tracking) is a monitoring measure, not an eradication technique. Option C (revoking cloud permissions) is relevant to access control but does not remove embedded malware. Option D (network scans) supports broader investigation but does not directly eliminate the persistent mobile threat.

ECIH guidance for malware eradication includes isolating infected devices, disabling malicious processes, applying clean firmware or OS reinstallation if necessary, and ensuring persistence mechanisms are removed. Therefore, switching the phone to safe mode before cleanup is the most appropriate eradication step.

A negligent insider is an individual within an organization who, due to a lack of knowledge on security threats or in an attempt to increase workplace efficiency, inadvertently bypasses security procedures or makes errors that compromise security. This type of insider threat is not malicious in intent; rather, it stems from carelessness, oversight, or a lack of proper security training. Such insiders might click on phishing links, mishandle sensitive information, or use unsecured networks for work-related tasks, thereby exposing the organization to potential security breaches. This contrasts with compromised insiders (who are manipulated by external parties), professional insiders (who misuse their access for personal gain), and malicious insiders (who intentionally aim to harm the organization).

Michael ' s activities, which involve analyzing file systems, slack spaces, and metadata of storage units to find hidden malware and evidence of malice, indicate that he is handling a storage-related cloud security incident. This type of incident pertains to unauthorized access, alteration, or exfiltration of data stored in cloud environments. By focusing on the storage aspects such as file systems and metadata, Michael is looking for signs of compromise that specifically affect the storage of data, which is indicative of a storage-related security incident in the cloud.

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.

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.
