When malicious files are detected and quarantined, the files and registry settings are copied and encrypted into a quarantine folder on the endpoint. The Quarantine 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.
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 > Quarantine 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
The following options are available in the Actions menu of the Quarantine page.
- 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.
- 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.
- Delete: Submits a task to the endpoint to permanently delete the encrypted quarantined items.
- Restore & Create Exclusion: Restore and create exclusions on the selected quarantined items.
The following columns are available on the Quarantine page:
- Threat name: Name of the quarantined threat.
- Category: Category of quarantined threat, such as malware or ransomware.
- Type: Type of threat, such as file or registry key.
- Endpoint: Endpoint the file was quarantined from.
- Location: File path of quarantined threat.
- Date: Date and time the threat was quarantined.
- Device: USB device the threat was quarantined from.
