@Soong, Brendon Thanks for reaching out to Microsoft Q&A.
The listblobs
API does not return the user who modified a certain file. However, you can use Azure Blob Storage logs to monitor the activity of your storage account and identify the security principal used to authorize a request. The logs show the operation name, authentication type, requester object ID, and other information. You can use the requester object ID to identify the security principal in Azure Active Directory.
For more information, see the article "Best practices for monitoring Azure Blob Storage" in the Azure documentation. The article provides information on how to monitor your Azure Blob Storage using metrics and logs - https://learn.microsoft.com/en-us/azure/storage/blobs/blob-storage-monitoring-scenarios#audit-account-activity
Please let me know if this helps or if you are looking for anything else and I will be glad to assist you further. Thank you!
