Playbook Series: Investigate & Contain

Today’s post continues an ongoing series on Playbooks; which Phantom uses to automate and orchestrate your security operations plan.

Playbooks are Python scripts that Phantom interprets in order to execute your mission when you see something that you want to take action on. Playbooks hook into the Phantom platform and all of its capabilities in order to execute actions, ensuring a repeatable and auditable process around your security operations. Sample community Playbooks can be customized at will and are synchronized via Git and published on our public Community GitHub repository. You can read more about Phantom and Playbooks here.

The spotlight Playbook for today was showcased at the Innovation Sandbox competition at RSAC. (If you haven’t already heard the news, Phantom won the competition this year!)

In this scenario, malware infects a host before the Command & Control traffic is seen by Sourcefire’s Network IPS. The event is logged to Splunk where it is correlated with other access logs or web logs to provide a high-fidelity malware detection event. Splunk forwards the event to Phantom for orchestration where the following actions are taken automatically:

  • List the VM’s in the VMWare environment by querying the vSphere server.
  • Find the IP address in the list of VM’s, then snapshot the VM and download it.
  • Run the snapshot through Volatility to find the malware process in memory and extract it.
  • With the file identified, get the hash and check the file reputation in ReversingLabs.
  • Assuming ReversingLabs doesn’t return enough data to convict, detonate the file in Cuckoo to identify additional indicators.
  • If Cuckoo returns enough data to convict the file, terminate the process on patient zero using Carbon Black, and block the file across the environment using a Windows File policy.
  • Finally, alert the SecOps team, the Help Desk, and the system owner that Phantom automatically took these countermeasures.

The savings are substantial for an organization that sees even an average volume of events. You can read more about the ROI of Automation & Orchestration here.
