Security Vulnerability Attempt on blocked port

Recommended Posts

Received the below Security Vulnerability Exploitation attempt but confused as the server sits in Azure with all traffic blocked by the NSG inbound so cannot see why ESET alerting for this (Known Bad) IP for this attempt.

Can anyone explain or seen similar alerts that do not make sense?

Just concerned that something has even attempted to exploit this server as it has no inbound ports open.

My understanding is that the communication first goes through ESET's firewall and only then it's evaluated by NSG which would account for ESET's detections.

Thanks for the reply but I do not understand how that could be, the traffic should hit the NSG First and be blocked and ESET should never see it as the communication is inbound.
