• Total files scanned—The total number of files in the organization scanned for potential malware. This will also show a status as to whether the scan is complete or in progress.
• Platforms—The number of platforms where malicious files were found.
• Malware found—The total number of files found deemed malicious.
• Users with malware—The number of users in your environment whose files contain malware.

3. Filter by platform(s).
   The platforms available for Cloud Malware are AWS S3, Azure Storage, Box, Dropbox, Google, Microsoft 365 (both OneDrive and SharePoint), ServiceNow, Slack, and Webex Teams. You can filter your malicious files' results by selecting any or all of the platforms licensed in your environment.

4. Filter by exposure.
   You can filter your malicious files by the type of exposure they pose to the environment. By default, none are selected, so all exposure types are presented.

5. Filter by status.
   Each file displays a status depending on whether it is newly discovered; a quarantine or restoration is in progress or failed; or if the file was successfully quarantined, restored, or deleted.

6. Optionally, you can choose to view Potentially Unwanted Applications (PUAs).

View Detailed Information About a File

You can view detailed information about any file listed in the report, such as its owner, location, and size.

1. Click the Action Menu to the right of the file of interest, then select See Full Details.

2. Review the information that appears.

Quarantine a Malicious File

On the Microsoft OneDrive, SharePoint Online, Box, Dropbox, ServiceNow, or Google Drive, when a malicious file presents a potential risk and needs remediation, you can manually quarantine the file. Only the integration user for the platform will have access to the quarantined files.

1. Click the Action Menu to the right of the file that needs to be quarantined, then select Quarantine.

2. A dialog box appears to verify the file is to be quarantined. Click QUARANTINE. The status will update to Quarantine in Progress while the quarantine is processing. This process can take up to five minutes; when complete, the status will update to Quarantined.

Note:

• For Microsoft OneDrive, SharePoint Online, Box, Dropbox, or Google Drive:

• The file identified as exposing sensitive data is moved to the Cisco_Quarantine/DLP folder Umbrella created in the root path of the Global Admin who authorized the tenant.
• The user who authorizes access to Umbrella will have access to the quarantine folder. All other accesses and collaborators are removed. Thus, we recommend that the admin add the relevant DLP Admins as additional collaborators to the folder.

• For ServiceNow:

• The file identified as exposing sensitive data is moved to a table named Cisco_Quarantine_Malware which can be access only by the admin user who authorized the ServiceNow tenant.
• A footprint is attached to the notes\activities area of the table the file is attached to. This footprint will notify users that the file has been identified as malware, and for more information they should contact their administrator.

• Quarantine attempts may fail if the files have been locked or blocked by settings within their native platforms. Settings local to the platform where a file resides take precedence over Umbrella’s ability to detect or remediate DLP violations or malware.

Restore a Quarantined File

On the Microsoft OneDrive, SharePoint Online, Box, Dropbox, ServiceNow, or Google Drive platforms, you can restore a file that has previously been quarantined.

Note: Once a file has been quarantined and then restored, it cannot be quarantined again.

1. Click the Action Menu to the right of the file that needs to be quarantined, then select Restore from Quarantine.

2. A dialog box appears to verify the file is to be restored. Click RESTORE. The status will update to Restoration in Progress while the file is being processed. This can take up to five minutes; when complete, the status will update to Restored.

Note: If your Cloud Malware deployment processes files from Microsoft OneDrive, SharePoint Online, Box, Dropbox, ServiceNow, or Google Drive and you restore a quarantined file that still violates rule criteria, the system will quarantine that file again. To prevent the system from quarantining the file again, remove the file's violation, or update the rule's criteria.

Delete a Malicious File

On the Webex Teams platform, when a malicious file presents a potential risk and needs remediation, you can delete the file.

1. Click the Action Menu to the right of the file that needs to be quarantined, then select Delete.

2. A dialog box appears to verify the file is to be deleted. Click Delete. The report status is updated to Deleted.

Dismiss an Item from the Report

When a reported file is found to not to present any risk, you can dismiss the file from the report.

1. Click the Action Menu to the right of the file that needs to be removed from the report, then select Dismiss.

2. A dialog box appears to verify the file is to be dismissed. Click OK. The file is removed from the report.
