NEW QUESTION # 53
An incident response team found IoCs in a critical server. The team needs to isolate and collect technical evidence for further investigation. Which of the following pieces of data should be collected first in order to preserve sensitive information before isolating the server?
- A. Primary boot partition
- B. Hard disk
- C. Routing table
- D. Static IP address
- E. Malicious files
Answer: E
Explanation:
Collecting malicious files is important because they can provide valuable information about the nature of the attack, the malware used, and potentially even the threat actor responsible. It allows for analysis without altering the system's state. Once the malicious files are collected, you can proceed with isolating the server and taking other steps to secure the environment.
NEW QUESTION # 54
An incident response analyst notices multiple emails traversing the network that target only the administrators of the company. The email contains a concealed URL that leads to an unknown website in another country. Which of the following best describes what is happening? (Choose two.)
- A. Beaconinq
- B. Domain Name System hijacking
- C. On-path attack
- D. Social engineering attack
- E. Obfuscated links
- F. Address Resolution Protocol poisoning
Answer: D,E
Explanation:
A social engineering attack is a type of cyberattack that relies on manipulating human psychology rather than exploiting technical vulnerabilities. A social engineering attack may involve deceiving, persuading, or coercing users into performing actions that benefit the attacker, such as clicking on malicious links, divulging sensitive information, or granting access to restricted resources. An obfuscated link is a link that has been disguised or altered to hide its true destination or purpose. Obfuscated links are often used by attackers to trick users into visiting malicious websites or downloading malware. In this case, an incident response analyst notices multiple emails traversing the network that target only the administrators of the company. The email contains a concealed URL that leads to an unknown website in another country. This indicates that the analyst is witnessing a social engineering attack using obfuscated links.
NEW QUESTION # 55
Several reports with sensitive information are being disclosed via file sharing services. The company would like to improve its security posture against this threat. Which of the following security controls would best support the company in this scenario?
- A. Increase password complexity standards.
- B. Implement step-up authentication for administrators.
- C. Improve employee training and awareness.
- D. Deploy mobile device management.
Answer: C
Explanation:
Improving employee training and awareness is the best option to address the issue of sensitive reports being disclosed via file sharing services. By educating employees about the risks of unapproved file sharing, the security protocols to follow, and the proper channels to use for sharing company information, an organization can significantly reduce the risk of sensitive data being accidentally or intentionally shared on insecure platforms. This human-centric approach addresses the root cause of the problem. Options A, C, and D are security controls that do not directly address the behavior of sharing sensitive files on unauthorized services.
NEW QUESTION # 56
A company brings in a consultant to make improvements to its website. After the consultant leaves. a web developer notices unusual activity on the website and submits a suspicious file containing the following code to the security team:
Which of the following did the consultant do?
Implanted a backdoor
Implemented privilege escalation
Implemented clickjacking
Patched the web server
- A. Implanted a backdoor.
Answer: A
Explanation:
A backdoor is a method that allows an unauthorized user to access a system or network without the permission or knowledge of the owner. A backdoor can be installed by exploiting a software vulnerability, by using malware, or by physically modifying the hardware or firmware of the device. A backdoor can be used for various malicious purposes, such as stealing data, installing malware, executing commands, or taking control of the system.
In this case, the consultant implanted a backdoor in the website by using an HTML and PHP code snippet that displays an image of a shutdown button and an alert message that says "Exit". However, the code also echoes the remote address of the server, which means that it sends the IP address of the visitor to the attacker. This way, the attacker can identify and target the visitors of the website and use their IP addresses to launch further attacks or gain access to their devices.
The code snippet is an example of a clickjacking attack, which is a type of interface-based attack that tricks a user into clicking on a hidden or disguised element on a webpage. However, clickjacking is not the main goal of the consultant, but rather a means to implant the backdoor. Therefore, option C is incorrect.
Option B is also incorrect because privilege escalation is an attack technique that allows an attacker to gain higher or more permissions than they are supposed to have on a system or network. Privilege escalation can be achieved by exploiting a software vulnerability, by using malware, or by abusing misconfigurations or weak access controls. However, there is no evidence that the consultant implemented privilege escalation on the website or gained any elevated privileges.
Option D is also incorrect because patching is a process of applying updates to software to fix errors, improve performance, or enhance security. Patching can prevent or mitigate various types of attacks, such as exploits, malware infections, or denial-of-service attacks. However, there is no indication that the consultant patched the web server or improved its security in any way.

NEW QUESTION # 57
A security analyst has found the following suspicious DNS traffic while analyzing a packet capture:
* DNS traffic while a tunneling session is active.
* The mean time between queries is less than one second.
* The average query length exceeds 100 characters.
Which of the following attacks most likely occurred?
- A. DNS zone transfer
- B. DNS poisoning
- C. DNS spoofing
- D. DNS exfiltration
Answer: D
Explanation:
DNS exfiltration is a technique that uses the DNS protocol to transfer data from a compromised network or device to an attacker-controlled server. DNS exfiltration can bypass firewall rules and security products that do not inspect DNS traffic. The characteristics of the suspicious DNS traffic in the question match the indicators of DNS exfiltration, such as:
DNS traffic while a tunneling session is active: This implies that the DNS protocol is being used to create a covert channel for data transfer.
The mean time between queries is less than one second: This implies that the DNS queries are being sent at a high frequency to maximize the amount of data transferred.
The average query length exceeds 100 characters: This implies that the DNS queries are encoding large amounts of data in the subdomains or other fields of the DNS packets.

NEW QUESTION # 58
Some hard disks need to be taken as evidence for further analysis during an incident response.
Which of the following procedures must be completed FIRST for this type of evidence acquisition?
- A. Perform a disk sanitization using the command #dd if=/dev/zero of=/dev/sdc bs=1M over the media that will receive a copy of the collected data.
- B. Execute the command #dd if-/dev/sda of=/dev/sdc bs=512 to clone the evidence data to external media to prevent any further change.
- C. Build the chain-of-custody document, noting the media model, serial number, size, vendor, date, and time of acquisition.
- D. Extract the hard drives from the compromised machines and then plug them into a forensics machine to apply encryption over the stored data to protect it from nonauthorized access.
Answer: C
Explanation:
Chain of custody should be done before taking a copy of data, because this defines what tools were used to obtain the data/who handled the copying. This is a crucial step for submitting data to court because this can help (along with hashing obv) prove the integrity of data.
NEW QUESTION # 59
A security analyst wants to capture large amounts of network data that will be analyzed at a later time. The packet capture does not need to be in a format that is readable by humans, since it will be put into a binary file called "packetCapture." The capture must be as efficient as possible, and the analyst wants to minimize the likelihood that packets will be missed. Which of the following commands will best accomplish the analyst's objectives?
- A. nmap -oA > packetCapture
- B. tcpdump -w packetCapture
- C. tcpdump -a packetCapture
- D. nmap -v > packetCapture
- E. tcpdump -n packetCapture
Answer: B
Explanation:
The tcpdump command is a network packet analyzer tool that can capture and display network traffic. The -w option specifies a file name to write the captured packets to, in a binary format that can be read by tcpdump or other tools later. This option is useful for capturing large amounts of network data that will be analyzed at a later time, as the question requires. The packet capture does not need to be in a format that is readable by humans, since it will be put into a binary file called "packetCapture". The capture must be as efficient as possible, and the -w option minimizes the processing and output overhead of tcpdump, reducing the likelihood that packets will be missed.

NEW QUESTION # 65
A virtual web server in a server pool was infected with malware after an analyst used the internet to research a system issue. After the server was rebuilt and added back into the server pool, users reported issues with the website, indicating the site could not be trusted. Which of the following is the most likely cause of the server issue?
- A. The server was configured to use SSI- to securely transmit data
- B. The server was supporting weak TLS protocols for client connections.
- C. The digital certificate on the web server was self-signed
- D. The malware infected all the web servers in the pool.
Answer: C
Explanation:
A digital certificate is a document that contains the public key and identity information of a web server, and is signed by a trusted third-party authority called a certificate authority (CA). A digital certificate allows the web server to establish a secure connection with the clients using the HTTPS protocol, and also verifies the authenticity of the web server. A self-signed certificate is a digital certificate that is not signed by a CA, but by the web server itself. A self-signed certificate can cause issues with the website, as it may not be trusted by the clients or their browsers. Clients may receive warnings or errors when trying to access the website, indicating that the site could not be trusted or that the connection is not secure. Official References:

NEW QUESTION # 67
A technician is analyzing output from a popular network mapping tool for a PCI audit:
Which of the following best describes the output?
- A. The Secure Shell port on this host is closed
- B. The host is not up or responding.
- C. The host is running excessive cipher suites.
- D. The host is allowing insecure cipher suites.
Answer: D
Explanation:
The output shows the result of running the ssl-enum-ciphers script with Nmap, which is a tool that can scan web servers for supported SSL/TLS cipher suites. Cipher suites are combinations of cryptographic algorithms that are used to establish secure communication between a client and a server. The output shows the cipher suites that are supported by the server, along with a letter grade (A through F) indicating the strength of the connection. The output also shows the least strength, which is the strength of the weakest cipher offered by the server. In this case, the least strength is F, which means that the server is allowing insecure cipher suites that are vulnerable to attacks or have been deprecated. For example, the output shows that the server supports SSLv3, which is an outdated and insecure protocol that is susceptible to the POODLE attack. The output also shows that the server supports RC4, which is a weak and broken stream cipher that should not be used.
Therefore, the best description of the output is that the host is allowing insecure cipher suites. The other descriptions are not accurate, as they do not reflect what the output shows. The host is not up or responding is incorrect, as the output clearly shows that the host is up and responding to the scan. The host is running excessive cipher suites is incorrect, as the output does not indicate how many cipher suites the host is running, only which ones it supports. The Secure Shell port on this host is closed is incorrect, as the output does not show anything about port 22, which is the default port for Secure Shell (SSH). The output only shows information about port 443, which is the default port for HTTPS.
NEW QUESTION # 68

NEW QUESTION # 69
A technician identifies a vulnerability on a server and applies a software patch. Which of the following should be the next step in the remediation process?
- A. Rollback
- B. Validation
- C. Testing
- D. Implementation
Answer: B
Explanation:
The next step in the remediation process after applying a software patch is validation. Validation is a process that involves verifying that the patch has been successfully applied, that it has fixed the vulnerability, and that it has not caused any adverse effects on the system or application functionality or performance. Validation can be done using various methods, such as scanning, testing, monitoring, or auditing.
