Splunk log4j

[revanthammineni]

Hello Splunkers,

I’ve created a search to show up all the log4j related events by looking into the strings. We are trying to dig into the events and schedule an alert.

Are there any particular messages we should check in the events for log4j vulnerability? Any particular events that has high risk factor? 

thanks in advance.
