問題 #339
Recently, the employees of a company have been receiving emails that seem to be from their colleagues, but with suspicious attachments. When opened, these attachments appear to install malware on their systems. The IT department suspects that this is a targeted malware attack.
Which of the following measures would be the most effective in preventing such attacks?
答案：D
問題 #340
The configuration allows a wired or wireless network interface controller to pass all traffic it receives to the Central Processing Unit (CPU), rather than passing only the frames that the controller is intended to receive.
Which of the following is being described?
答案：B
解題說明：
The correct answer is A because the description matches promiscuous mode. In normal operation, a network interface card processes frames addressed to its own MAC address, broadcast frames, or relevant multicast frames, while ignoring frames not intended for it. In promiscuous mode, the NIC passes all received frames up to the operating system or packet-capture tool for inspection. CEH sniffing concepts describe this as a key requirement for sniffers: the NIC is placed into promiscuous mode so it can listen to all data transmitted on its segment, even when the traffic is not addressed to that NIC. CEH-aligned material also states that a sniffer needs the card to run in promiscuous mode so the NIC grabs frames regardless of address. Port forwarding redirects traffic between ports or hosts, WEM is not the described network-interface behavior, and multicast mode only handles multicast traffic.
問題 #341
During a routine security audit at a large financial services organization, the IT team detects severe network latency and recurring bandwidth exhaustion across its corporate WAN links. Upon deeper investigation, they discover that several employee workstations and IoT-connected devices are unknowingly transmitting enormous volumes of traffic to numerous external IP addresses. These devices, all exhibiting similar traffic patterns and command-response behaviors, are found to be under the control of a remote botnet operator. The incident raises serious concerns about insider-originated denial-of-service activity that is also affecting external entities. Which type of denial-of-service attack best describes the organization's current situation?
答案：D
解題說明：
The organization's compromised internal workstations and IoT devices are being controlled as part of a botnet and are actively generating large volumes of outbound traffic toward external targets, which characterizes a botnet-driven distributed denial-of-service attack originating from infected internal systems.
問題 #342
A healthcare organization in Seattle detects unusual activity on an endpoint after a phishing campaign. During the investigation, analysts discover that a Microsoft Word document automatically launched a PowerShell script upon opening, which then initiated remote command execution without the user ' s knowledge.
The security team determines that identifying this abnormal execution pattern is more effective than relying solely on known malicious IP addresses or file hashes.
What category of Indicators of Compromise (IOCs) best represents the evidence identified in this investigation?
答案：A
解題說明：
Behavioral Indicators is the best answer because the decisive evidence is not a static artifact such as an IP address, domain, or file hash; it is the execution relationship itself: Microsoft Word spawning PowerShell and PowerShell initiating remote command execution. Behavioral indicators describe suspicious process, registry, file, and network activity patterns and are intended to detect attacker techniques even when easily changed atomic indicators are absent. A host-based indicator can include files, registry keys, or other endpoint artifacts, but this question specifically contrasts abnormal execution behavior with known hashes and addresses. CEH v13 Malware Threats emphasizes malware behavior and analysis, while modern behavioral IOC guidance likewise focuses on process-level actions and tactics. Therefore, the observed Office-to- PowerShell execution chain is classified most precisely as a Behavioral Indicator.
問題 #343
In the bustling financial hub of Charlotte, North Carolina, ethical hacker Raj Patel is contracted by TrustBank, a regional US bank, to evaluate their online loan application portal. On April 22, 2025, Raj tests a feature allowing customers to upload structured financial documents for loan processing. By submitting a specially crafted document, he triggers a response that exposes internal server file paths and sensitive configuration data, including database connection strings.
The issue arises from the portal's handling of external references in document parsing, not from response manipulation, authentication weaknesses, or undetected attack attempts. Raj compiles a detailed report to assist TrustBank's security team in mitigating the vulnerability. Which type of vulnerability is Raj most likely exploiting in TrustBank's online loan application portal?
答案：B
解題說明：
The vulnerability involves submitting a crafted document that leverages external references during parsing to access internal files and sensitive configuration data. This behavior is characteristic of XML External Entity injection, where improperly configured XML parsers process external entities and expose system-level information.
