NEW QUESTION # 31
Which attack works like a dictionary attack, but adds some numbers and symbols to the words from the dictionary and tries to crack the password?
Answer: D
Explanation:
A Hybrid Attack is a type of cyber attack that combines elements of a dictionary attack with a brute force attack. It involves taking words from a dictionary (which could be a list of common passwords or related words) and augmenting them with numbers and symbols to generate potential passwords. This method increases the chances of cracking a password by including the common variations that users often add to their passwords to meet complexity requirements.
References: The EC-Council's Certified SOC Analyst (CSA) resources describe various types of attacks and their methodologies. According to these resources, a Hybrid Attack specifically refers to this combined approach, which is more sophisticated than a simple dictionary attack and is designed to overcome the limitations of dictionary attacks by including additional characters1.
NEW QUESTION # 32
Which of the following command is used to view iptables logs on Ubuntu and Debian distributions?
Answer: C
Explanation:
In Ubuntu and Debian distributions, the command to view iptables logs is $ tailf /var/log/kern.log. This command allows you to follow the end of the kernel log file in real-time. It is useful for monitoring the logs as they are updated. The tailf command is similar to tail -f, and it displays the last ten lines of the file by default and then outputs appended data as the file grows.
References:The answer is verified according to the EC-Council's Certified SOC Analyst (CSA) course materials and study guides, which cover the practical aspects of security operations and incident handling, including the monitoring of systems and logs123.
NEW QUESTION # 33
A multinational financial institution notices unusual network activity during a routine security audit. The SOC detects multiple failed login attempts, followed by a successful access attempt using an administrator's credentials from an unrecognized IP address. Shortly after, sensitive customer records are accessed without authorization. The company suspects a breach and calls in the forensic investigation team. During evidence collection, the forensic team creates a detailed record that tracks every individual who handled the evidence, its storage location, and timestamps of transfers. What is this process called?
Answer: B
Explanation:
Chain of custody is the formal process used to document and preserve evidence integrity by recording who collected the evidence, who accessed it, where it was stored, and when it changed hands. In SOC and forensic operations, chain of custody is essential for maintaining evidentiary reliability, especially in cases with regulatory, legal, or disciplinary implications. It ensures that evidence has not been altered, tampered with, or mishandled, and it supports defensible conclusions about what occurred. Incident documentation is broader and includes timelines, decisions, actions taken, and communications, but it does not specifically track evidence handling transfers. Data imaging is the creation of a forensic copy of storage media (disk image), a separate technical step that may be recorded within chain-of-custody logs. Digital fingerprinting refers to generating hashes or other identifiers to confirm file integrity; again, it is a technique used within evidence handling, but the tracking record of handlers, locations, and transfers is chain of custody. For SOC analysts, correctly maintaining chain of custody is critical when responding to breaches involving sensitive customer records and potential compliance investigations.
NEW QUESTION # 34
DNS logs in the SIEM show an internal host sending many DNS queries with long, encoded subdomains to an external domain. The queries predominantly use TXT records and occur during off-business hours. The external domain is newly registered and has no known business association. Which option best explains this behavior?
Answer: B
Explanation:
The described pattern is highly consistent with DNS tunneling used for command-and-control or data exfiltration. Long, encoded subdomains are commonly used to embed data into DNS queries because DNS labels can carry arbitrary text that can be base32/base64/hex encoded. TXT records are frequently abused in tunneling because they can return larger payloads and are flexible for exchanging data between malware and an external resolver or authoritative DNS infrastructure controlled by an attacker. The fact that this occurs off- hours and targets a newly registered domain with no business relationship increases suspicion and reduces the likelihood of legitimate use. DNS cache poisoning attempts would typically show anomalies in resolver behavior, unexpected DNS responses, or mismatched records, not a high volume of encoded outbound queries from a single internal host. Rogue DNS servers would present as internal hosts acting as resolvers or responding to many DNS queries, not sending encoded TXT queries outward. Legitimate record validation might involve standard query types (A/AAAA/CNAME) and normal domain names, not long encoded subdomains. For SOC triage, the next steps would include identifying the originating process/host, blocking the domain, capturing related network flows, and scoping for other hosts with similar DNS patterns.
NEW QUESTION # 35
The Syslog message severity levels are labelled from level 0 to level 7.
What does level 0 indicate?
Answer: C
Explanation:
In the Syslog protocol, severity levels are categorized from 0 to 7, with level 0 being the most severe. Level 0 indicates an "Emergency" situation which means the system is unusable. This level of severity is used for the most critical messages, often indicating a complete service or system shutdown.
