UID 99 (nobody) Tracking Hit - DST=88.221.134.194

[node27]

Hi,

Looking for some help from people if anyone has any idea.

Shortly before and during an inbound syn DDOS attack on https on my server yesterday I notice some weird alerts from CSF Firewall reporting weird outbound traffic.

The IP address is included in the logs as this is null routed and no longer in use.

I interpret the logs as my server was trying to make outbound connections to DST=88.221.134.194. This ip is an AKAMAI CDN IP address. These alerts were being sent every couple of minutes.

My provider have reported it was only an inbound SYN flood not a reflection attack.

Does anyone have an idea what was going on her and what us at DST=88.221.134.194.??

Thanks
Ant
