We are using Coretex Paloalto XDR. From yesterday, in one of our application servers, the web.config file automatically disappears. We checked the incedent logs in XDR but no incedent or log found. it happened twice from yesterday .

Hello @RNagarajan

Thank you for reaching out on LiveCommunity!

If the given file was disappeared by XDR then you will be able to see it under Incident Response -> Action Center -> Currently Applied Actions -> File Quarantine. This scenario is possible if you have configured the malware security profile to quarantine malicious executables and the given file is malicious.

Otherwise, if you have enabled the endpoint data collection you can take help from Query Builder. Go to Incident Response -> Query Builder -> File. Here you can search the file with name and/or other parameters along with various file operation types. This will show you the file history for the selected time period.

Also looking into the alert table directly can help you find the alert related to this file if triggered. In the alert table you can filter alerts based on file path and file hash values.
