We are a esports portal site in China. Our CS:GO tournament kicked off today.
But during some of today’s matches, our CS:GO server was under UDP flooding
attack. The attacker used port 27005 to send massive packets to our server
port. Then the ping of our server went as high as 700s, which rendered the
match unable to continue.
I managed to capture some attacking packets with Microsoft Network Monitor. But
I was not able to decode them. They are displayed in HEX format with unreadable
codes. How can I know what they are sending?
And more importantly, how can I stop such kind of attacks?
Best regards,
