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.

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.
