Hi all, my first time on this forum. I am a network engineer student in college and need some help. I have discovered an FTP attack on my web server. This is not the first time this has happened. I want to somehow take action against these guys. Below is a capture of the packets going into my server:
Just use a program like Wireshark to read it (free multi-platform packet reader)
Here is the info I was able to pull up on the guy (and my info says its not behind a proxy):
inetnum: 18.104.22.168 - 22.214.171.124
descr: 21vianet (shanghai), Inc.
descr: 129 Yan An Rd(W.) Shanghai, China
status: ALLOCATED PORTABLE
changed: firstname.lastname@example.org 20060224
person: Xiaoqiu Liu
address: 129 Yan An Rd(W.) Shanghai, China
changed: email@example.com 20050920
Can anyone assist me with what my next step should be?
The server wasn't up for 2 days when I noticed FTP attack attempts from China. I don't know what their deal is, but simply blocking the IP range seems to have worked so far.. until I get a honeypot setup
