Palo Alto Networks - Hunting And Threat Detection
This is a multipurpose playbook used for hunting and threat detection. The playbook receives inputs based on hashes, IP addresses, or domain names provided manually or from outputs by other playbooks. With the received indicators, the playbook leverages data received by PANW products including, Cortex Data Lake, Autofocus and Pan-OS to search for IP addresses, host names and users related to the provided indicators. The output provided by the playbook facilitates pivoting searches for possibly affected IP addresses or users.

Playbook Inputs#
| Name | Description | Default Value | Required |
|---|---|---|---|
| SHA256 | SHA256 hash of the indicator to hunt. | Optional | |
| MD5 | MD5 hash of the indicator to hunt. | Optional | |
| SHA1 | SHA1 hash of the indicator to hunt. | Optional | |
| IPAddresses | List of IP addresses. | Optional | |
| URLDomain | List of domains or urls. | Optional | |
| InternalRange | A list of internal IP ranges to check IP addresses against. The list should be provided in CIDR notation, separated by commas. An example of a list of ranges would be: "172.16.0.0/12,10.0.0.0/8,192.168.0.0/16" (without quotes). If a list is not provided, will use default list provided in the IsIPInRanges script (the known IPv4 private address ranges). | Optional | |
| InternalDomainName | The organizations internal domain name. This is provided for the script IsInternalHostName that checks if the detected host names are internal or external if the hosts contain the internal domains suffix. For example demisto.com. If there is more than one domain, use the | character to separate values such as (demisto.com|test.com) | Optional | |
| InternalHostRegex | This is provided for the script IsInternalHostName that checks if the detected host names are internal or external. If the hosts match the organization's naming convention. For example the host testpc1 will have the following regex \w{6}\d{1} | Optional |
