NEW QUESTION # 12
What is the purpose of the Unit 42 team?
Answer: C
Explanation:
Unit 42 is the threat intelligence and response team of Palo Alto Networks. The purpose of Unit 42 is to collect and analyze the most up-to-date threat intelligence and apply it to respond to cyberattacks. Unit 42 is composed of world-renowned threat researchers, incident responders and security consultants who help organizations proactively manage cyber risk. Unit 42 is responsible for threat research, malware analysis and threat hunting, among other activities12.
Let's briefly discuss the other options to provide a comprehensive explanation:
A . Unit 42 is not responsible for automation and orchestration of products. Automation and orchestration are capabilities that are provided by Palo Alto Networks products such as Cortex XSOAR, which is a security orchestration, automation and response platform that helps security teams automate tasks, coordinate actions and manage incidents3.
B . Unit 42 is not responsible for the configuration optimization of the Cortex XDR server. The Cortex XDR server is the cloud-based platform that provides detection and response capabilities across network, endpoint and cloud data sources. The configuration optimization of the Cortex XDR server is the responsibility of the Cortex XDR administrators, who can use the Cortex XDR app to manage the settings and policies of the Cortex XDR server4.
C . Unit 42 is not responsible for the rapid deployment of Cortex XDR agents. The Cortex XDR agents are the software components that are installed on endpoints to provide protection and visibility. The rapid deployment of Cortex XDR agents is the responsibility of the Cortex XDR administrators, who can use various methods such as group policy objects, scripts, or third-party tools to deploy the Cortex XDR agents to multiple endpoints5.
In conclusion, Unit 42 is the threat intelligence and response team of Palo Alto Networks that is responsible for threat research, malware analysis and threat hunting. By leveraging the expertise and insights of Unit 42, organizations can enhance their security posture and protect against the latest cyberthreats.

NEW QUESTION # 13
How does Cortex XDR agent for Windows prevent ransomware attacks from compromising the file system?
Answer: A
Explanation:
Cortex XDR agent for Windows prevents ransomware attacks from compromising the file system by utilizing decoy files. Decoy files are randomly generated files that are placed in strategic locations on the endpoint, such as the user's desktop, documents, and pictures folders. These files are designed to look like valuable data that ransomware would target for encryption. When Cortex XDR agent detects that a process is attempting to access or modify a decoy file, it immediately blocks the process and alerts the administrator. This way, Cortex XDR agent can stop ransomware attacks before they can cause any damage to the real files on the endpoint. Reference:

NEW QUESTION # 14
Which of the following is NOT a precanned script provided by Palo Alto Networks?
Answer: C
Explanation:
Palo Alto Networks provides a set of precanned scripts that you can use to perform various actions on your endpoints, such as deleting files, killing processes, or quarantining malware. The precanned scripts are written in Python and are available in the Agent Script Library in the Cortex XDR console. You can use the precanned scripts as they are, or you can customize them to suit your needs. The precanned scripts are:
delete_file: Deletes a specific file from a local or removable drive.
quarantine_file: Moves a specific file from its location on a local or removable drive to a protected folder and prevents it from being executed.
process_kill_name: Kills a process by its name on the endpoint.
process_kill_pid: Kills a process by its process ID (PID) on the endpoint.
process_kill_tree: Kills a process and all its child processes by its name on the endpoint.
process_kill_tree_pid: Kills a process and all its child processes by its PID on the endpoint.
process_list: Lists all the processes running on the endpoint, along with their names, PIDs, and command lines.
process_list_tree: Lists all the processes running on the endpoint, along with their names, PIDs, command lines, and parent processes.
process_start: Starts a process on the endpoint by its name or path.
registry_delete_key: Deletes a registry key and all its subkeys and values from the Windows registry.
registry_delete_value: Deletes a registry value from the Windows registry.
registry_list_key: Lists all the subkeys and values under a registry key in the Windows registry.
registry_list_value: Lists the value and data of a registry value in the Windows registry.
registry_set_value: Sets the value and data of a registry value in the Windows registry.
The script list_directories is not a precanned script provided by Palo Alto Networks. It is a custom script that you can write yourself using Python commands.

NEW QUESTION # 15
Cortex XDR is deployed in the enterprise and you notice a cobalt strike attack via an ongoing supply chain compromise was prevented on 1 server. What steps can you take to ensure the same protection is extended to all your servers?
Answer: D
Explanation:
The best step to ensure the same protection is extended to all your servers is to create indicators of compromise (IOCs) of the malicious files you have found to prevent their execution. IOCs are pieces of information that indicate a potential threat or compromise on an endpoint, such as file hashes, IP addresses, domain names, or registry keys. You can create IOCs in Cortex XDR to block or alert on any file or network activity that matches the IOCs. By creating IOCs of the malicious files involved in the cobalt strike attack, you can prevent them from running or spreading on any of your servers.
The other options are not the best steps for the following reasons:
A is not the best step because conducting a thorough Endpoint Malware scan may not detect or prevent the cobalt strike attack if the malicious files are obfuscated, encrypted, or hidden. Endpoint Malware scan is a feature of Cortex XDR that allows you to scan endpoints for known malware and quarantine any malicious files found. However, Endpoint Malware scan may not be effective against unknown or advanced threats that use evasion techniques to avoid detection.
B is not the best step because enabling DLL Protection on all servers may cause some false positives and disrupt legitimate applications. DLL Protection is a feature of Cortex XDR that allows you to block or alert on any DLL loading activity that matches certain criteria, such as unsigned DLLs, DLLs loaded from network locations, or DLLs loaded by specific processes. However, DLL Protection may also block or alert on benign DLL loading activity that is part of normal system or application operations, resulting in false positives and performance issues.
C is not the best step because enabling Behavioral Threat Protection (BTP) with cytool may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection. Behavioral Threat Protection is a feature of Cortex XDR that allows you to block or alert on any endpoint behavior that matches certain patterns, such as ransomware, credential theft, or lateral movement. Cytool is a command-line tool that allows you to configure and manage the Cortex XDR agent on the endpoint. However, Behavioral Threat Protection may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection, such as encryption, obfuscation, or proxy servers.

NEW QUESTION # 16
An attacker tries to load dynamic libraries on macOS from an unsecure location. Which Cortex XDR module can prevent this attack?
Answer: D
Explanation:
The correct answer is D. Dylib Hijacking. Dylib Hijacking, also known as Dynamic Library Hijacking, is a technique used by attackers to load malicious dynamic libraries on macOS from an unsecure location. This technique takes advantage of the way macOS searches for dynamic libraries to load when an application is executed. To prevent such attacks, Palo Alto Networks offers the Dylib Hijacking prevention capability as part of their Cortex XDR platform. This capability is designed to detect and block attempts to load dynamic libraries from unauthorized or unsecure locations1.
Let's briefly discuss the other options to provide a comprehensive explanation:
A . DDL Security: This is not the correct answer. DDL Security is not specifically designed to prevent dynamic library loading attacks on macOS. DDL Security is focused on protecting against DLL (Dynamic Link Library) hijacking on Windows systems2.
B . Hot Patch Protection: Hot Patch Protection is not directly related to preventing dynamic library loading attacks. It is a security feature that protects against runtime patching or modification of code in memory, often used by advanced attackers to bypass security measures3. While Hot Patch Protection is a valuable security feature, it is not directly relevant to the scenario described.
C . Kernel Integrity Monitor (KIM): Kernel Integrity Monitor is also not the correct answer. KIM is a module in Cortex XDR that focuses on monitoring and protecting the integrity of the macOS kernel. It detects and prevents unauthorized modifications to critical kernel components4. While KIM plays an essential role in overall macOS security, it does not specifically address the prevention of dynamic library loading attacks.
In conclusion, Dylib Hijacking is the Cortex XDR module that specifically addresses the prevention of attackers loading dynamic libraries from unsecure locations on macOS. By leveraging this module, organizations can enhance their security posture and protect against this specific attack vector.
