Description

@Richman711

Describe the enhancement:
Requesting an update to the winlogbeat\module\sysmon\config\winlogbeat-sysmon.js to include event 26 for correct parsing into elasticsearch using the sysmon module.

The new sysmon event id is nearly identical to event id 23 except for the archived boolean.

DATA: RuleName, UtcTime, ProcessGuid, ProcessId, User, Image, TargetFilename, Hashes, IsExecutable

In Symon 13.21.0.0 the application supports the use of schema version 4.70 which can be verified by running the latest sysmon executable from Microsoft as .\sysmon.exe -s

<Sysmon schemaversion="4.70">
   <EventFiltering>
      <RuleGroup name="" groupRelation="or">
         <FileDeleteDetected onmatch="exclude">
            <User condition="contains any">NETWORK SERVICE; LOCAL SERVICE</User>
         </FileDeleteDetected>
      </RuleGroup>
   </EventFiltering>
</Sysmon>

Describe a specific use case for the enhancement or feature:

Like event ID 23; Event ID 26 also hashes the deletion of files but without archiving the deleted file in C:\Sysmon allowing its use in areas outside of a malware sandbox or in IR triage. Maintaining a record of deleted files along with hashes can facilitate historical lookups during compromise investigations to identify which hosts have been affected by identified IoCs.
