問題 #73
Under which conditions is Local Analysis evoked to evaluate a file before the file is allowed to run?

答案：A

解題說明：
Local Analysis is a feature of Cortex XDR that allows the agent to evaluate files locally on the endpoint, without sending them to WildFire for analysis. Local Analysis is evoked when the following conditions are met:
The endpoint is disconnected from the internet or the Cortex XDR management console, and therefore cannot communicate with WildFire.
The verdict from WildFire is of a type unknown, meaning that WildFire has not yet analyzed the file or has not reached a conclusive verdict.
Local Analysis uses machine learning models to assess the behavior and characteristics of the file and assign it a verdict of either benign, malware, or grayware. If the verdict is malware or grayware, the agent will block the file from running and report it to the Cortex XDR management console. If the verdict is benign, the agent will allow the file to run and report it to the Cortex XDR management console. Reference:
Local Analysis
WildFire File Verdicts


問題 #74
A Linux endpoint with a Cortex XDR Pro per Endpoint license and Enhanced Endpoint Data enabled has reported malicious activity, resulting in the creation of a file that you wish to delete. Which action could you take to delete the file?

答案：B

解題說明：
The best action to delete the file on the Linux endpoint is to initiate Remediation Suggestions from the Cortex XDR console. Remediation Suggestions are a feature of Cortex XDR that provide you with recommended actions to undo the effects of malicious activity on your endpoints. You can view the remediation suggestions for each alert or incident in the Cortex XDR console, and decide whether to apply them or not. Remediation Suggestions can help you restore the endpoint to its original state, remove malicious files or processes, or fix registry or system settings. Remediation Suggestions are based on the forensic data collected by the Cortex XDR agent and the analysis performed by Cortex XDR.
The other options are incorrect for the following reasons:
A is incorrect because manually remediating the problem on the endpoint is not a convenient or efficient way to delete the file. Manually remediating the problem would require you to access the endpoint directly, log in as root, locate the file, and delete it. This would also require you to have the necessary permissions and credentials to access the endpoint, and to know the exact path and name of the file. Manually remediating the problem would also not provide you with any audit trail or confirmation of the deletion.
B is incorrect because opening X2go from the Cortex XDR console is not a supported or secure way to delete the file. X2go is a third-party remote desktop software that allows you to access Linux endpoints from a graphical user interface. However, X2go is not integrated with Cortex XDR, and using it would require you to install and configure it on both the Cortex XDR console and the endpoint. Using X2go would also expose the endpoint to potential network attacks or unauthorized access, and would not provide you with any audit trail or confirmation of the deletion.
D is incorrect because opening an NFS connection from the Cortex XDR console is not a feasible or reliable way to delete the file. NFS is a network file system protocol that allows you to access files on remote servers as if they were local. However, NFS is not integrated with Cortex XDR, and using it would require you to set up and maintain an NFS server and client on both the Cortex XDR console and the endpoint. Using NFS would also depend on the network availability and performance, and would not provide you with any audit trail or confirmation of the deletion.

問題 #75
As a Malware Analyst working with Cortex XDR you notice an alert suggesting that there was a prevented attempt to download Cobalt Strike on one of your servers. Days later, you learn about a massive ongoing supply chain attack. Using Cortex XDR you recognize that your server was compromised by the attack and that Cortex XDR prevented it. What steps can you take to ensure that the same protection is extended to all your servers?

答案：C

解題說明：
To ensure that the same protection is extended to all your servers, you need to create Behavioral Threat Protection (BTP) rules to recognize and prevent the activity. BTP is a feature of Cortex XDR that allows you to create custom rules that detect and block malicious or suspicious behaviors on your endpoints, such as file execution, process injection, network connection, or registry modification. BTP rules can use various operators, functions, and variables to define the criteria and the actions for the rules. By creating BTP rules that match the behaviors of the supply chain attack, you can prevent the attack from compromising your servers12.
Let's briefly discuss the other options to provide a comprehensive explanation:
B . Enable DLL Protection on all servers but there might be some false positives: This is not the correct answer. Enabling DLL Protection on all servers will not ensure that the same protection is extended to all your servers. DLL Protection is a feature of Cortex XDR that allows you to block the execution of unsigned or untrusted DLL files on your endpoints. DLL Protection can help to prevent some types of attacks that use malicious DLL files, but it may not be effective against the supply chain attack that used a Trojanized DLL file that was digitally signed by a trusted vendor. DLL Protection may also cause some false positives, as it may block some legitimate DLL files that are unsigned or untrusted3.
C . Create IOCs of the malicious files you have found to prevent their execution: This is not the correct answer. Creating IOCs of the malicious files you have found will not ensure that the same protection is extended to all your servers. IOCs are indicators of compromise that you can create to detect and respond to known threats on your endpoints, such as file hashes, registry keys, IP addresses, domain names, or full paths. IOCs can help to identify and block the malicious files that you have already discovered, but they may not be effective against the supply chain attack that used different variants of the malicious files with different hashes or names. IOCs may also become outdated, as the attackers may change or update their files to evade detection4.
D . Enable Behavioral Threat Protection (BTP) with cytool to prevent the attack from spreading: This is not the correct answer. Enabling BTP with cytool will not ensure that the same protection is extended to all your servers. BTP is a feature of Cortex XDR that allows you to create custom rules that detect and block malicious or suspicious behaviors on your endpoints, such as file execution, process injection, network connection, or registry modification. BTP rules can help to prevent the attack from spreading, but they need to be created and configured in the Cortex XDR app, not with cytool. Cytool is a command-line tool that allows you to perform various operations on the Cortex XDR agent, such as installing, uninstalling, upgrading, or troubleshooting. Cytool does not have an option to enable or configure BTP rules.
In conclusion, to ensure that the same protection is extended to all your servers, you need to create BTP rules to recognize and prevent the activity. By using BTP rules, you can create custom and flexible prevention rules that match the behaviors of the supply chain attack.

問題 #76
Which version of python is used in live terminal?

答案：D

解題說明：
Live terminal uses Python 3 with standard Python libraries to run Python commands and scripts on the endpoint. Live terminal does not support Python 2 or any custom or external Python libraries. Live terminal uses the Python interpreter embedded in the Cortex XDR agent, which is based on Python 3.7.4. The standard Python libraries are the modules that are included with the Python installation and provide a wide range of functionalities, such as operating system interfaces, network programming, data processing, and more. You can use the Python commands and scripts to perform advanced tasks or automation on the endpoint, such as querying system information, modifying files or registry keys, or running other applications. Reference:
Run Python Commands and Scripts
Python Standard Library


問題 #77
Which statement is correct based on the report output below?

答案：D

解題說明：
The report output shows the number of endpoints that have forensic inventory data collection enabled, which is a feature of Cortex XDR that allows the collection of detailed information about the endpoint's hardware, software, and network configuration. This feature helps analysts to investigate and respond to incidents more effectively by providing a comprehensive view of the endpoint's state and activity. Forensic inventory data collection can be enabled or disabled per policy in Cortex XDR. Reference:
