Or you may have gotten an email or a message that says “Data Sentinel suspended overlay commit on the device”.

 

Hello John Smith,

Data Sentinel on ‘DESKTOP.domain.com’ in the account ‘Acme Corp. (company: Acme Corp.)’ suspended overlay commit schedule.

Reason: auto suspended by Data Sentinel after unusual file modification was detected

Suspension prevents unwanted changes or corrupted data from committing to disk while possible data breach is being investigated and remedied. However, you should resume its normal commit schedule promptly after the appropriate action is complete.

Why Am I Getting This?

This email is coming because the device had significant changes to the data and NeuShield is pausing to ensure that the changes are ok with you.

This happens when NeuShield detects too many changes on the overlay that look like good data might have been replaced with unknown or encrypted data. For example if the overlay has a bunch of encrypted files on it and the hard disk has a bunch of legitimate documents on it and the commit cycle would replace the documents with the encrypted data the NeuShield would pause the commit and send this notification to let you know that there could be an issue on that computer (such as a ransomware attack).

How To Check What Was Modified?

The exact files that are modified to trigger this event are stored in the debug log (C:\Program Files\NeuShield\NeuShield Data Sentinel\DebugLog.txt). You can search the log yourself for the data.

Search debug log for:

xxx (yyy) has been maliciously modified

zzz seems have malicious deletions

Note: “xxx” is current file name and “yyy” is previous file name. “zzz” is the folder path.

The events are be visible on the NeuShield Portal under Client Activity.
