NEW QUESTION # 147
After a web application attack, HealthFirst traced the breach to an insecure Direct Object Reference (IDOR) vulnerability. They want to patch it and fortify the app. What should be their primary action?
Answer: B
Explanation:
IDOR is fundamentally an authorization flaw: the application exposes object identifiers (IDs) and fails to enforce that the requesting user is allowed to access that object. The primary remediation is to implement robust authorization checks-commonly RBAC (C) plus object-level access control-so every request verifies user identity and privileges against the requested resource.
(A) WAFs can help with certain injection patterns, but default WAF rules rarely fix logical authorization flaws like IDOR. A WAF also risks false positives and doesn't replace secure design. (B) pen testing is important for assurance, but it's not the primary patch; it helps validate the fix later. (D) encryption protects confidentiality in transit/at rest, but it does not prevent an authenticated user from accessing another user's records if authorization checks are missing.
Therefore (C) is the correct first-line fix: enforce authorization server-side, avoid predictable identifiers, and ensure access control is consistently applied across all endpoints (including APIs).
NEW QUESTION # 148
A multinational SaaS provider detects a major security breach involving unauthorized access to customer billing data in its EU and APAC servers. After triage and legal review, the IH&R team confirms data exfiltration impacting regulated regions. In response, the CISO, with legal and compliance teams, initiates a structured communication protocol-informing affected clients, notifying data protection authorities under laws such as GDPR, and preparing media responses with public affairs. All communications are securely routed, reviewed for legal accuracy, and sent only with executive approval to mitigate risk and misinformation. What type of communication is emphasized in this scenario?
Answer: B
Explanation:
The EC-Council Incident Handler (ECIH) curriculum outlines structured communication protocols as a critical part of incident management, particularly when regulated data and external stakeholders are involved.
When data breaches affect customers and fall under regulatory frameworks such as GDPR, organizations are legally required to notify affected individuals and data protection authorities within defined timelines.
The scenario describes communication with clients, regulatory authorities, and media representatives. These stakeholders are external to the organization. ECIH categorizes this as external communication, which must be carefully coordinated with legal, compliance, and executive leadership to ensure accuracy and regulatory compliance.
ECIH emphasizes that external communication must be controlled, legally reviewed, approved by executive leadership, and aligned with regulatory requirements to prevent misinformation and reduce reputational damage. This differs from internal updates or automated alerts.
Option A refers to automated technical notifications. Option C focuses on internal analysis discussions.
Option D relates to operational containment communications during malware handling.
Therefore, the scenario emphasizes structured external communication intended for non-organizational entities.
NEW QUESTION # 149
Lara, a SOC analyst, investigates multiple alerts generated by an IDS showing repeated login failures from a specific workstation to an internal application. When reviewing Windows Event Viewer logs, she discovers a user account repeatedly attempting logins outside of working hours.
Further checks reveal the user had installed an unauthorized remote desktop tool. Which of the following best describes this situation?
Answer: D
Explanation:
The key issue is the installation and use of an unauthorized remote desktop tool, combined with suspicious login activity outside working hours. This represents inappropriate usage because the user violated organizational policy by using unapproved software and access behavior.
NEW QUESTION # 150
Liam, a senior incident responder at a manufacturing company, is alerted to an email campaign distributing malware through fake invoice attachments. He confirms that some users opened the attachment, resulting in system slowdown and unauthorized access attempts. He disconnects affected machines, scans and removes malware, disables compromised accounts, restores systems from clean backups, and documents file hashes, sender IPs, and malicious domains. Which of the following best describes Liam's objective?
Answer: D
Explanation:
This scenario clearly aligns with the eradication phase of the ECIH malware incident handling lifecycle.
After detection and containment, eradication focuses on completely removing malicious artifacts and ensuring the threat cannot re-emerge.
Option D is correct because Liam's actions-malware removal, account disabling, system restoration, and IOC documentation-are all aimed at fully eliminating the malware and attacker footholds. ECIH emphasizes that eradication must address malware binaries, persistence mechanisms, compromised credentials, and residual indicators.
Option B (forensic preservation) would avoid system changes, which Liam does not do. Option A is a training activity unrelated to response. Option C is infrastructure improvement, not incident handling.
ECIH explicitly states that failure to eradicate all traces often leads to reinfection or continued attacker access.
Liam's comprehensive approach ensures the environment is returned to a trusted state and prepares detection systems for future prevention.
