Correlation rule for WannaCry detection detects unnecessary user authorisation
we have rule Exploit - Ransomware WannaCry Behavior Detected (Base Rule) which works fine as expected. But we have create another rule which detects occurrence of Base Rule but not in Source Zone All_Geuest_Network. It works more less correct but today it corelated Authentication events for NormID 408977408 which are not related to anything in Base Rule. We ware trying to find some relation but couldnt find anything.
I can provide more details and screen shots if needed
