#Splunk enterprise security sandbox software
This can involve installing and configuring a collection of software such as Wireshark, Regshot, and ProcMon to manually step through the execution of the malware while observing and documenting the actions. If you have ever created a sandbox environment for observing and analyzing malware, you know that setting up your sandbox can be a time-consuming process involving installation and configuration of dozens of different pieces of software. What files it downloads for the second or third stage of the attackĪfter observing the malware, you can take the information learned to create new detections and defenses, or hunt for other malicious activity within your network.The goal of dynamic analysis is to learn: Not only is Elastic a natural fit for instrumenting and collecting data from a sandbox, it is also easy to build and can be created within minutes.ĭynamic malware analysis is the act of executing and observing a suspicious piece of software inside an isolated VM.

In this blog post, I will demonstrate how the Elastic InfoSec team uses Fleet and Elastic Security as a fully instrumented malware sandbox. The Elastic InfoSec team is always pushing the limits with Elastic products as part of our Customer Zero effort so we decided to build a sandbox using Elastic products. In these cases, the security team needs to have a well-instrumented virtual machine (VM) sandbox that they can use to safely execute the file in question and observe what happens. If it wasn’t, they need to quickly understand what actions were taken on the host.

In these situations, the security team needs to quickly find out what has occurred on one of their systems when a file is executed to determine whether it would have been detected or stopped.
#Splunk enterprise security sandbox code
A common attack we see is phishing emails containing attachments that do not contain malicious code and thus do not set off any alerts, but they attempt to social engineer a user to steal their password. As a security analyst on Elastic’s InfoSec team, a common scenario we see is users coming to our team and asking: “Is this file safe to open?” Or one user reports a phishing email with an attachment that they didn’t open, but we see from the logs that 10 other users also received that email but didn’t report it and no alerts went off on their systems.
