Sandbox Analysis in Nebula

Malwarebytes Endpoint Detection and Response customers can use the Sandbox Analysis feature. This feature allows you to upload a file within the Nebula console and receive a comprehensive report on the item, indicating if the file is malicious or not. Reports display on the Sandbox Analysis page after a few minutes from the time you upload the file.

This article explains how to upload files for analysis, and the types of data you can investigate in the results table of the Sandbox Analysis page.

Upload file on the Sandbox Analysis page

  1. On the left navigation pane, go to Investigate > Sandbox Analysis.
  2. At the top of the Sandbox Analysis page, drag and drop a file or click browse computer to choose a file for upload. The following file parameters apply:
    • Max file size: 64 MB
    • File types accepted: PE 32/64bit (exe,dll)
  3. A window asks you to confirm the file upload. Click Confirm Upload to initiate the analysis process.

Uploading and analyzing a file may take a few minutes. Refresh the Sandbox Analysis page for an updated status. Once analysis is complete, the result displays in the table beneath the file upload area.
