'We have received reports of abuse coming from your Spring Server. Your server is being used in a brute force attack as these logs we received show:'
I have manage to get into the server and the advise was as below:
Even though the server is blocked, you can still log into it via the
spring console. Once in there check all the processes that you are
running and kill the process that is performing these brute force
attacks. You should also enable the firewall and block your server from
performing these attacks on port 22. You'll probably want to check for
any accounts on your server that you do not recognize and change your
root password in case it has been compromised. Let me know when you have
taken care of this and I'll unblock the server.
How do I check what process is running and kill the process that is performing these brute force attacks.
