When malicious files are detected and quarantined, the files and registry settings are copied and encrypted into a quarantine folder on the endpoint. The Quarantined Detections page in Nebula is an index for each item on the endpoint and allows you to restore or delete detected files. Items stay in this list until they are manually restored or deleted from the page. This page shows the quarantined detections data for the last 365 days.
While Nebula uses its best judgment whether a file is a threat, false positives are possible. You may also find items in Quarantine that are legitimate. View detected items and cross-check the information to verify if the file is legitimate with other Threat Intelligence databases, such as VirusTotal using the SHA256 hash of the file.
On the left navigation menu, go to Monitor > Detection Center > Quarantined Detections to view the list of all quarantined threat data. While this page shows all quarantined threats across your network, the actual threats remain encrypted on the endpoints where they were found. The quarantine location is a predefined folder on your endpoints:
- Windows endpoints: C:\ProgramData\Malwarebytes\MBAMService\Quarantine
- Mac endpoints: /Library/Application Support/Malwarebytes/NCEP/Quarantine/
- Linux endpoints: /var/lib/mblinux/quarantine
Manage quarantine
The following options are available in the Actions menu of the Quarantined Detections page.
- Delete: Submits a task to the endpoint to permanently delete the encrypted quarantined items.
- Restore: Moves the item from Quarantine back to its original location on the endpoint. If the device you're restoring a quarantined file to is a USB device, it must be connected to the same endpoint it was quarantined from. Use this for items you know are legitimate.
- Restore & Create Exclusion: Restore and create exclusions on the selected quarantined items.
- Create Exclusions: Create exclusions on the selected quarantined items. Only Super Admins can create exclusions. For more information on exclusions, see Overview of exclusions in Nebula.
- Download .csv: Export a report in .csv format containing the selected rows of data.
-
Download .xlsx: Export a report in .xlsx format containing the selected rows of data.
- If the data size is too large to download, an email will be sent instead with a link to download the export.
