NEW QUESTION # 128
Identify the password cracking attempt involving a precomputed dictionary of plaintext passwords and their corresponding hash values to crack the password.
- A. Syllable Attack
- B. Rainbow Table Attack
- C. Dictionary Attack
- D. Bruteforce Attack
Answer: B
Explanation:
A Rainbow Table Attack involves using a precomputed table of hash values for every possible combination of characters for a given password policy. This table, known as a rainbow table, is then used to look up the corresponding plaintext password for a given hash value. The process involves the following steps:
* Precomputation: Generate the rainbow table by computing hash values for all possible password combinations according to the password policy.
* Storage: Store these precomputed hash values in a table, associating each with its plaintext password.
* Lookup: When a hash value is obtained during a password cracking attempt, search the rainbow table for the corresponding plaintext password.
* Match: If a match is found, the plaintext password associated with the hash value is the cracked password.
Rainbow tables are effective because they trade storage space for time, allowing for quicker password cracking compared to brute-force or dictionary attacks, which compute hash values on the fly.
References: The EC-Council's materials on password cracking techniques discuss various methods including dictionary attacks, brute-force attacks, and rainbow table attacks. Specifically, the EC-Council Learning Paths and Skill Packs provide detailed insights into these techniques, emphasizing the use of rainbow tables as a method of cracking passwords by comparing precomputed hash values to those obtained from a system12. Additionally, EC-Council's CyberQ platform offers practical exercises related to password cracking, including the use of rainbow tables2.
NEW QUESTION # 129
What does the HTTP status codes 1XX represents?
- A. Redirection
- B. Client error
- C. Success
- D. Informational message
Answer: D
Explanation:
The HTTP status codes that fall within the range of 1XX represent informational messages. These are provisional responses that indicate the initial part of a request has been received and has not yet been rejected by the server. The server is informing the client that it has received the header of the request and the client should continue to send the request body if it has not already done so. These status codes are used to provide an interim response to the client while the server processes the full request.
References: The EC-Council's Certified SOC Analyst (C|SA) program includes the study of HTTP status codes as part of understanding web server logs and troubleshooting web server issues. The informational responses (1XX status codes) are covered in the curriculum and can be found in the official EC-Council SOC Analyst study guides and courses. The information is also consistent with the standard definitions provided by the Internet Engineering Task Force (IETF) in RFC 9110, as well as other reputable sources such as MDN Web Docs1 and Wikipedia2.
NEW QUESTION # 130
David Reynolds, a SOC analyst at a healthcare organization, is investigating suspicious login attempts flagged by the SIEM. To mitigate brute-force risk on targeted endpoints, he collaborates with IT to implement an automatic account lockout policy that temporarily disables accounts after multiple failed login attempts.
Within the SOC's eradication strategy, which category of measures does this action align with?
- A. Physical security measures
- B. Authentication and authorization measures
- C. Network security measures
- D. Host security measures
Answer: B
Explanation:
Account lockout is an identity control that directly strengthens authentication by limiting repeated password guessing attempts. It sits within authentication and authorization measures because it governs how accounts can authenticate and how access is granted or denied based on login outcomes. In SOC terms, brute-force attacks target the authentication surface; lockout policies reduce attacker attempts and can prevent successful compromise by forcing a pause or administrative intervention after repeated failures. While the policy may be implemented on hosts or via directory services, its purpose is to control identity access behavior, not network segmentation or physical protections. Host security measures typically refer to endpoint hardening, patching, EDR controls, and local configuration baselines. Network security measures include firewall rules, segmentation, and traffic filtering. Physical security includes facility and device access controls. Because the action is specifically about controlling login attempts and access to accounts, it is best categorized as authentication and authorization. In practice, SOC teams complement lockout policies with MFA, conditional access, password spraying detection, and monitoring for "failures followed by success" patterns to reduce both brute-force success and user disruption.

What is the process of monitoring and capturing all data packets passing through a given network using different tools?
- A. DNS Footprinting
- B. Network Sniffing
- C. Port Scanning
- D. Network Scanning
Answer: B
Explanation:
Networksniffing is the process of monitoring and capturing all data packets passing through a given network.
This is typically done using specialized software or hardware tools designed for this purpose. Here's a detailed explanation of the process:
* Monitoring Traffic: Network sniffing involves using a tool to monitor the data flowing over the network. This can include all types of data packets, regardless of where they come from or where they are going.
* Capturing Packets: The tool captures each packet that passes through the network. This includes the packet's header, which contains information about the packet's source, destination, and other metadata, as well as the payload, which is the actual data being transmitted.
* Analysis: Once captured, the packets can be analyzed for various purposes, such as troubleshooting network issues, monitoring network performance, or detecting security threats.
* Tools Used: There are many tools available for network sniffing, with Wireshark being one of the most popular and widely used due to its powerful features and flexibility1.
References: The concept of network sniffing is covered in EC-Council's Certified SOC Analyst (CSA) training and certification program, which includes understanding the use of tools like Wireshark for packet capturing and analysis213.

NEW QUESTION # 132
Juliea a SOC analyst, while monitoring logs, noticed large TXT, NULL payloads.
What does this indicate?
- A. Concurrent VPN Connections Attempt
- B. Covering Tracks Attempt
- C. DHCP Starvation Attempt
- D. DNS Exfiltration Attempt
Answer: D
Explanation:
Juliea, the SOC analyst, noticed large TXT and NULL payloads in the logs. This is indicative of a DNS exfiltration attempt. DNS exfiltration is a type of cyber attack where an attacker uses the DNS protocol to sneak data out of a network undetected. It typically involves the use of large TXT records, which can be used to carry data out of the network. NULL payloads can be used in this context to pad the DNS queries and make them less suspicious or to bypass security controls that inspect the content of DNS queries.
The steps involved in DNS exfiltration include:
* The attacker compromises a system within the target network.
* Malware on the compromised system encodes the data it wants to exfiltrate.
* The encoded data is split into chunks that fit into DNS query sizes.
* These chunks are sent as data in DNS queries or responses, often using TXT records.
* An external attacker-controlled server receives the DNS queries and decodes the data.
References:
* EC-Council's Certified SOC Analyst (CSA) course material and study guides provide detailed information on various types of cyber attacks, including DNS exfiltration.
* Online resources and practice questions for the Certified SOC Analyst (CSA) exam also cover this topic and can be used to verify the answer123.
* Additional information on DNS exfiltration techniques and detection methods can be found in security blogs and articles that discuss the subject in depth456.
