• Question 91:

  Which statement best describes how Behavioral Threat Protection (BTP) works?

  A. BTP injects into known vulnerable processes to detect malicious activity.
  B. BTP runs on the Cortex XDR and distributes behavioral signatures to all agents.
  C. BTP matches EDR data with rules provided by Cortex XDR.
  D. BTP uses machine Learning to recognize malicious activity even if it is not known.
  D. BTP uses machine Learning to recognize malicious activity even if it is not known.

  ---

  Explanation

  The statement that best describes how Behavioral Threat Protection (BTP) works is D, BTP uses machine learning to recognize malicious activity even if it is not known. BTP is a feature of Cortex XDR that allows you to define custom rules to detect and block malicious behaviors on endpoints. BTP uses machine learning to profile behavior and detect anomalies indicative of attack. BTP can recognize malicious activity based on file attributes, registry keys, processes, network connections, and other criteria, even if the activity is not associated with any known malware or threat. BTP rules are updated through content updates and can be managed from the Cortex XDR console.

  The other statements are incorrect for the following reasons: A is incorrect because BTP does not inject into known vulnerable processes to detect malicious activity.

  BTP does not rely on process injection, which is a technique used by some malware to hide or execute code within another process. BTP monitors the behavior of all processes on the endpoint, regardless of their vulnerability status, and compares them with the BTP rules. B is incorrect because BTP does not run on the Cortex XDR and distribute behavioral signatures to all agents. BTP runs on the Cortex XDR agent, which is installed on the endpoint, and analyzes the endpoint data locally. BTP does not use behavioral signatures, which are predefined patterns of malicious behavior, but rather uses machine learning to identify anomalies and deviations from normal behavior. C is incorrect because BTP does not match EDR data with rules provided by Cortex XDR. BTP is part of the EDR (Endpoint Detection and Response) capabilities of Cortex XDR, and uses the EDR data collected by the Cortex XDR agent to perform behavioral analysis. BTP does not match the EDR data with rules provided by Cortex XDR, but rather applies the BTP rules defined by the Cortex XDR administrator or the Palo Alto Networks threat research team.

• Question 92:

  What motivation do ransomware attackers have for returning access to systems once their victims have paid?

  A. There is organized crime governance among attackers that requires the return of access to remain in good standing.
  B. Nation-states enforce the return of system access through the use of laws and regulation.
  C. Failure to restore access to systems undermines the scheme because others will not believe their valuables would be returned.
  D. The ransomware attackers hope to trace the financial trail back and steal more from traditional banking institutions. -
  C. Failure to restore access to systems undermines the scheme because others will not believe their valuables would be returned.

  ---

  Explanation

  Ransomware attackers have a motivation to return access to systems once their victims have paid because they want to maintain their reputation and credibility. If they fail to restore access to systems, they risk losing the trust of future victims who may not believe that paying the ransom will result in getting their data back. This would reduce the effectiveness and profitability of their scheme. Therefore, ransomware attackers have an incentive to honor their promises and decrypt the data after receiving the ransom.

• Question 93:

  Which type of IOC can you define in Cortex XDR?

  A. Destination IP Address
  B. Source IP Address
  C. Source port
  D. Destination IP Address: Destination
  A. Destination IP Address

  ---

  Explanation

  Cortex XDR allows you to define IOC rules based on various types of indicators of compromise (IOC) that you can use to detect and respond to threats in your network. One of the types of IOC that you can define in Cortex XDR is destination IP address, which is the IP address of the remote host that a local endpoint is communicating with. You can use this type of IOC to identify malicious network activity, such as connections to command and control servers, phishing sites, or malware distribution hosts. You can also specify the direction of the network traffic (inbound or outbound) and the protocol (TCP or UDP) for the destination IP address IOC.

• Question 94:

  As a Malware Analyst working with Cortex XDR you notice an alert suggesting that there was a prevented attempt to open a malicious Word document. You learn from the WildFire report and AutoFocus that this document is known to have been used in Phishing campaigns since 2018.

  What steps can you take to ensure that the same document is not opened by other users in your organization protected by the Cortex XDR agent?

  A. Enable DLL Protection on all endpoints but there might be some false positives.
  B. Create Behavioral Threat Protection (BTP) rules to recognize and prevent the activity.
  C. No step is required because Cortex shares IOCs with our fellow Cyber Threat Alliance members.
  D. No step is required because the malicious document is already stopped.
  B. Create Behavioral Threat Protection (BTP) rules to recognize and prevent the activity.

  ---

  Explanation

  The correct answer is B, create Behavioral Threat Protection (BTP) rules to recognize and prevent the activity. BTP rules are a powerful feature of Cortex XDR that allow you to define custom rules to detect and block malicious behaviors on endpoints. You can use BTP rules to create indicators of compromise (IOCs) based on file attributes, registry keys, processes, network connections, and other criteria. By creating BTP rules, you can prevent the same malicious Word document from being opened by other users in your organization, even if the document has a different name or hash value. BTP rules are updated through content updates and can be managed from the Cortex XDR console. The other options are incorrect for the following reasons: A is incorrect because enabling DLL Protection on all endpoints is not a specific or effective way to prevent the malicious Word document. DLL Protection is a feature of Cortex XDR that prevents the loading of unsigned or untrusted DLLs by protected processes. However, this feature does not apply to Word documents or macros, and may cause false positives or compatibility issues with legitimate applications.

• Question 95:

  Which of the following features is primarily used to manage agent updates in Cortex XDR?

  A. Agent Installations
  B. Asset Management
  C. Report Scheduling
  D. Incident Prioritization
  A. Agent Installations

  ---

  Explanation

  Agent Installations is the feature in Cortex XDR used for managing agent updates, including the installation and upgrade of agents across endpoints. Option B, while it provides visibility into asset data, does not focus on managing agent updates. Options C and D are unrelated.

• Question 96:

  Which module in Cortex XDR provides the best visibility into vulnerabilities present on endpoints?

  A. Host Insights
  B. Security Manager
  C. Forensics
  D. Incident Management
  A. Host Insights

  ---

  Explanation

  The Host Insights module in Cortex XDR provides comprehensive visibility into vulnerabilities across the endpoints, including missing patches and software vulnerabilities. Option B and C focus on other areas like security management and forensic analysis, and D relates to incident management, not vulnerability assessment.

• Question 97:

  Which Type of IOC can you define in Cortex XDR?

  A. destination port
  B. e-mail address
  C. full path
  D. App-ID
  C. full path

  ---

  Explanation

  Cortex XDR allows you to define IOCs based on various criteria, such as file hashes, registry keys, IP addresses, domain names, and full paths. A full path IOC is a specific location of a file or folder on an endpoint, such as C:\Windows \System32\calc.exe. You can use full path IOCs to detect and respond to malicious files or folders that are located in known locations on your endpoints 12. Let's briefly discuss the other options to provide a comprehensive explanation:

  A. destination port: This is not the correct answer. Destination port is not a type of IOC that you can define in Cortex XDR. Destination port is a network attribute that indicates the port number to which a packet is sent. Cortex XDR does not support defining IOCs based on destination ports, but you can use XQL queries to filter network events by destination ports3.

  B. e-mail address: This is not the correct answer. E-mail address is not a type of IOC that you can define in Cortex XDR. E-mail address is an identifier that is used to send and receive e-mails. Cortex XDR does not support defining IOCs based on e-mail addresses, but you can use the Cortex XDR - IOC integration with Cortex XSOAR to ingest IOCs from various sources, including e-mail addresses4.

  D. App-ID: This is not the correct answer. App-ID is not a type of IOC that you can define in Cortex XDR. App-ID is a feature of Palo Alto Networks firewalls that identifies and controls applications on the network. Cortex XDR does not support defining IOCs based on App-IDs, but you can use the Cortex XDR Analytics app to create custom rules that use App-IDs as part of the rule logic5. In conclusion, full path is the type of IOC that you can define in Cortex XDR. By using full path IOCs, you can enhance your detection and response capabilities and protect your endpoints from malicious files or folders.

• Question 98:

  How does Cortex XDR agent for Windows prevent ransomware attacks from compromising the file system?

  A. by encrypting the disk first.
  B. by utilizing decoy Files.
  C. by retrieving the encryption key.
  D. by patching vulnerable applications.
  B. by utilizing decoy Files.

  ---

  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.
