This document and video will illustrate the power of Falcon Sandbox and how it differentiates itself from other solutions in the market.

What is Falcon Sandbox?
Falcon Sandbox is a malware analysis tool that can be delivered via the cloud or on premise. It provides a safe, complete malware analysis to help streamline investigations and enable security operations teams provide faster threat protection and response.
Falcon Sandbox also provides customization options such as operating systems for detonation, command line parameters, variables and passwords.
How does Falcon Sandbox analysis add value?
After submitting a sample for analysis, the sandbox will run the sample and collect critical information on its behavior.
Immediately, you are presented with a threat assessment and score. In this case, the file was found to be malicious with a 100/100 score. The top of the report provides the hash of the file as well as a risk assessment overview.
There is also a link to the MITRE ATT&CK techniques that are related to the sample. This information summarizes the likely objectives of the malware and the techniques used to accomplish those objectives.
Further down in the report is a complete breakdown of all of the observed indicators. They are categorized as malicious, suspicious and informative.
In addition to that, the hybrid analysis provides a process tree and access to additional information about how the sample behaved including details of any API calls, registry changes, etc.
How can Falcon Sandbox improves overall security?
For samples that can be attributed to a bad actor, Falcon Sandbox will include that information in the sandbox report. This lets you know who is targeting your organization so that you can take steps to protect the organization accordingly.
The Sandbox can also provide actor attribution including a link to the full actor profile. With that attribution, you can see the larger picture and take action on indicators like known command and control domains and leveraged vulnerabilities.
Falcon Sandbox analysis also includes integration with CrowdStrike’s Malquery tool. This compares the provided sample against CrowdStrike’s unparalleled repository of malware to find potential commonalities and relationships. You can see the hash values of related malware and download Yara rules for your own investigations.
Lastly, under Network Analysis, you will find the option to download a list of resolved domains, IP addresses, and ports used by the sample the sample. That information can be shared with the perimeter security team to establish blocks against any such traffic in the future.
Falcon Sandbox gives malware researchers and security operations teams the information that they need to provide their organization with faster threat protection and response. Deployment options offer flexibility while the tool provides customization options, hybrid analysis and contextual information to provide your organization with actionable information.

How to Contain an Infected System
Hi, there. My name’s Peter Ingebrigtsen. And today, we’ve logged into the falcon.crowdstrike.com, or the Falcon User Interface.
And what we’re going to do is take a look at some of our systems and recognize that some of them are either currently under attack or recently been under attack, and may have been compromised. And we’d like to contain that system until we can further get to it, get our hands on it, and get a little bit more information out of it, or just prevent it from doing any more damage than it’s already done.
In order to do that, you need to be on your Detections app. You can do that by going to the radar here on the left-hand side. If you’re not already, or if your user interface doesn’t open that when you first log in, head there. And then just select the Recent Detections.
When that opens, you’ll notice that you can filter by any number of criteria, but we’re looking at some of the more recent events or situations that are going on. And you’ll notice that the same single machine has noticed a lot of different scenarios with privilege escalation or web exploits. And these severities are high to critical.
And we’d like to log in there, maybe do a little something, take a little closer look, and see if there’s something we should do. Obviously, we should do something. And as we start to dig through here, we see that there’s a lot of detection patterns, whether that be known malware, credential theft, or web exploits. We can see in the process tree a lot of different commands that were issued that look at that privilege escalation that we noticed earlier– or start to set that up.
So, we know that there’s something bad going on, and we’d like to take action right away. So, what we want to do is network contain this machine. But what I want to show you, as well, is that as we do this– I’m going to go to the machine itself. And I’d like to start a continuous ping so that you can watch the behavior and how long it takes to respond to this network containment.
Now, while we contain this– or take this machine off the network– we don’t kill the connection to the CrowdStrike Cloud. So, that as we get our hands on it– we clean it up, we feel comfortable putting it back on to the network– we can still operate or control that machine through the user interface that we have here.
The other thing I’d like to do is start a large download, so that we initiate with a single TCP connection– and there happens to be one in process– as opposed to the ping, where there may be multiple TCP resets or individual TCP threads going every time. So that you can see that as we contain this machine, it literally just knocks it off the network.
Forgive my screen, but I’ve changed the resolution for YouTube and for appearance purposes.
But as I come in here– and this will be right at the middle of the screen– this actually says Device Actions. And I’d like to contain it.
Now, as we do that, we have some options to make some notes. Contained by Peter. Multiple threats observed. Whatever notes you’d like to make– and then select Contain.
Now, the second we do this, on the left-hand side, you’ll see how quickly it takes for that to respond. So, immediately, almost in real time, you see a network failure on the download, and the ping test– or the continuous ping fail. So, we can close that.
Now, let’s say we’re a couple days later, this machine’s cleaned up, ready to go, and be put back in the network. You can go ahead and lift the network containment, again, from the user interface. We still have that connection to the machine, even though all the other network connections have been terminated.
So, as we do that, all good. Uncontain. And you’ll notice that almost immediately that ping starts to fire right back up again.
So, network containment is a powerful tool that we can use if we see something immediately taking action or if we see something recently in the past, and we’d like to get that machine off the network– almost quarantine it– so that it can’t do any more damage.
So, this has been network containment of network devices in the Falcon Sensor User Interface platform. Thanks again for watching.
