There were 602143 of different source IPs participing the SYN flood to 204.188.216.183 within the 15 minutes (from 11:40 to 11:55) window,

the sources IPs definitely look spoofed to me.

And except the following 3 hosts, all the rest pretty much only had 1 or 2 SYN request

count(*)    sip    proto    dport    tcpflags    size dist

1338    121.125.67.246    TCP    80    ....S.    48,52

244    216.3.66.10    TCP    80    ....S.    48,52

24    114.203.113.101    TCP    80    ....S.    48,52

And for tcp traffic, all are SYN requests, and they are either 48 or 52 byte large.

I got nothing for 89.45.193.200.

Let me know if you need the raw flow data, thanks

Regards
