This document and video will demonstrate how to use Falcon Spotlight to find exploitable vulnerabilities in your environment to help prioritize which systems may have a great need for patching.
Spotlight for Reporting
In today’s threat landscape there is no shortage of things that need to get done. Many companies deal with an overwhelming number of alerts and investigations everyday. There is always a new attack in the news or product update that needs to be deployed. CrowdStrike recognizes that the demands on security professionals continue to grow.
In the Spotlight dashboard CVEs are already categorized by their Common Vulnerability Scoring System or CVSS Base Score, and that is a great place to start. But if that is the only prioritization method used to determine which systems get patched significant time might be wasted.
The “Exploited Vulnerabilities feature,” is an example of Falcon Spotlight offering ways to ease the demands on security professionals by simplifying the process of mitigating higher risk vulnerabilities.
To access the exploited vulnerabilities Spotlight, click in the filter bar and find the “Exploit Status” qualifier.
Using the filtering capabilities, Spotlight can add an additional filter called “Exploit Status” to quickly identify vulnerabilities for which an exploit exists, is readily available, or actively being used. This is an inclusive filter, so selecting all vulnerabilities that have an exploit ‘available’ will also include exploits that are easily accessible and actively being used.
In just a matter of clicks The Spotlight app has gone from identifying thousands of vulnerabilities in the organization, to highlighting the specific vulnerabilities that have a higher probability of being exploited and putting systems at risk. Using the vulnerability view we can export a report to help us focus on systems that have a high number of exploitable vulnerabilities.
Falcon Spotlight provides holistic access to the actual vulnerability status of your environment, not just reported status. With simple reporting and real time results without introducing complex hardware or time consuming scans. It provides complete, actionable reporting to help make your organization more secure.
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.
