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 isnota precanned script provided by Palo Alto Networks. It is a custom script that you can write yourself using Python commands.

Ransomware is a type of malicious software, or malware, that encrypts user files and prevents them from accessing their data until they pay a ransom. Ransomware can affect individual users, businesses, and organizations of all kinds. Ransomware attacks can cause costly disruptions, data loss, and reputational damage. Ransomware can spread through various methods, such as phishing emails, malicious attachments, compromised websites, or network vulnerabilities. Some ransomware variants can also self-propagate and infect other devices or networks. Ransomware authors typically demand payment in cryptocurrency or other untraceable methods, and may threaten to delete or expose the encrypted data if the ransom is not paid within a certain time frame. However, paying the ransom does not guarantee that the files will be decrypted or that the attackers will not target the victim again.Therefore, the best way to protect against ransomware is to prevent infection in the first place, and to have a backup of the data in case of an attack123456

Ransomware --- FBI

The kind of malware that uses encryption, data theft, denial of service, and possibly harassment to take advantage of a victim isransomware. Ransomware is a type of malware that encrypts the victim's files or blocks access to their system, and then demands a ransom for the decryption key or the restoration of access. Ransomware can also threaten to expose or delete the victim's data if the ransom is not paid. Ransomware can cause significant damage and disruption to individuals, businesses, and organizations, and can be difficult to remove or recover from. Some examples of ransomware are CryptoLocker, WannaCry, Ryuk, and REvil.

TheHost Insights moduleprovides the best visibility to view vulnerabilities on your endpoints. The Host Insights module is an add-on feature for Cortex XDR that combines vulnerability management, application and system visibility, and a Search and Destroy feature to help you identify and contain threats. The vulnerability management feature allows you to scan your Windows endpoints for known vulnerabilities and missing patches, and view the results in the Cortex XDR console. You can also filter and sort the vulnerabilities by severity, CVSS score, CVE ID, or patch availability. The Host Insights module helps you reduce your exposure to threats and improve your security posture.Reference:

The difference between presets and datasets in XQL is that a dataset is a built-in or third-party data source, while a preset is a group of XDR data fields. A dataset is a collection of data that you can query and analyze using XQL. A dataset can be a Cortex data lake data source, such as endpoints, alerts, incidents, or network flows, or a third-party data source, such as AWS CloudTrail, Azure Activity Logs, or Google Cloud Audit Logs. A preset is a predefined set of XDR data fields that are relevant for a specific use case, such as process execution, file operations, or network activity. A preset can help you simplify and standardize your XQL queries by selecting the most important fields for your analysis. You can use presets with any Cortex data lake data source, but not with third-party data sources.Reference:
