Answer : C

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.Reference:

To manually upgrade the Cortex XDR agents, you can use theAsset Managementpage or theEndpoint Administrationpage in the Cortex XDR console. On the Asset Management page, you can select one or more endpoints and clickActions > Upgrade Agent. On the Endpoint Administration page, you can select one or more agent versions and clickUpgrade. You can also schedule automatic agent upgrades using theAgent Installationspage.Reference:

Answer : B

File Search and Destroy is a feature of Cortex XDR that allows you to search for and remove malicious files from endpoints. You can use this feature to find files by their hash, full path, or partial path using regex parameters. You can then select the files from the search results and destroy them by hash or by path. When you destroy a file by hash, all the file instances on the endpoint are removed. File Search and Destroy is useful for quickly responding to threats and preventing further damage.Reference:

Cortex XDR supports Live Terminal for Android systems, which allows you to remotely access and manage Android endpoints using a command-line interface. You can use Live Terminal to run Android commands, such asadb shell,adb logcat,adb install, andadb uninstall. You can also use Live Terminal to view and modify files, directories, and permissions on the Android endpoints. Live Terminal for Android systems does not support stopping an app or running APK scripts.Reference:

To automatically convert leads into alerts after investigating a lead, you should create IOC rules based on the set of the collected attribute-value pairs over the affected entities concluded during the lead hunting. IOC rules are used to detect known threats based on indicators of compromise (IOCs) such as file hashes, IP addresses, domain names, etc. By creating IOC rules from the leads, you can prevent future occurrences of the same threats and generate alerts for them.Reference:

Answer : C, D

You can star security events in Cortex XDR in two ways: manually star an alert or an incident, or create an alert-starring or incident-starring configuration. Starring security events helps you prioritize and track the events that are most important to you. You can also filter and sort the events by their star status in the Cortex XDR console.

To manually star an alert or an incident, you can use the star icon in the Alerts table or the Incidents table. You can also star an alert from the Causality View or the Query Center Results table. You can star an incident from the Incident View or the Query Center Results table. You can also unstar an event by clicking the star icon again.

To create an alert-starring or incident-starring configuration, you can use the Alert Starring Configuration or the Incident Starring Configuration pages in the Cortex XDR console. You can define the criteria for starring alerts or incidents based on their severity, category, source, or other attributes. You can also enable or disable the configurations as needed.

Answer : B

Live Terminal uses theWebSocketprotocol to communicate with the agent on the endpoint. WebSocket is a full-duplex communication protocol that enables bidirectional data exchange between a client and a server over a single TCP connection. WebSocket is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. WebSocket provides a persistent connection between the Cortex XDR console and the endpoint, allowing you to execute commands and receive responses in real time. Live Terminal uses port 443 for WebSocket communication, which is the same port used for HTTPS traffic.Reference:
