Investigating and responding to malware alerts can take 30 minutes or more. Use the Splunk Phantom Malware Hunt and Contain playbook to automate the investigation and response process, determine whether a process is malicious, and take immediate action to block the hash on infected endpoints.

Load data

How to implement: To run the Splunk Phantom Malware Hunt and Contain playbook, you need a Splunk Enterprise instance from which Phantom can draw data that ingests Windows security and authentication events.

Although there are several ways to get data into Phantom, this example uses the Phantom App for Splunk on Splunkbase. Verify that the playbook is configured to operate on splunk_events.

Before you run the playbook, verify that Splunk Phantom is receiving data from Splunk Enterprise. Also, verify your asset configurations on the Phantom Asset Configuration page, and that all assets are resolved on the Phantom Resolved Assets page.

Get insights

The Splunk Phantom Malware Hunt and Contain playbook is triggered by any suspicious or confirmed malicious processes that require further evaluation.

The Splunk Phantom Malware Hunt and Contain playbook performs a reputation lookup against a potentially malicious file hash. The output from the reputation lookup determines one of two possible containment actions, depending on conditions.

To find the playbook, go to the Phantom main menu, select Playbooks, and search for malware_hunt_and_contain.

How to respond: By default, the playbook uses a file hash from an alert, but you can modify it to get a copy of the file off of the endpoint based on a specified file path. You can then detonate this file in a sandbox to observe its behavior and get additional context and information about the file.
