Large Number of Failed Logins

[chasmcg]

In the last 24 hours I have had over 120 of these messages from CPanel (large number of failed logins). Mainly from Russia and China but from other countries as well. I suspect it's someone spoofing IPs. I get these messages all the time but nothing like the last 24 hours.

Does "cPHulk Brute Force Protection" ban those IPs each time they send me an email? I hope so. I have manually banned blocks of IPs but they just keep coming. What can be done about this? Thanks for any help or advice.

Hello,

Are these attempting to connect to your SSH service ? if so, Changing the default port number would be a very good option here.

Yes, the port number has been changed. But the attempts keeps coming. I have about 5 domains on my server. They're trying to FTP in as well on all domains. Thanks for your reply.

cHHulk only "protects" cPanel services. I would recommend CSF/LFD for automated blocking of IP addresses with excessive failed logins.

Hello

Yes, you will need to block those IP addresses with a firewall such as CSF. Note there are plans to implement blocking features in cPanel version 11.48:

cPHulkd to better mitigate Brute Force Attacks | cPanel Feature Requests

Thank you.

Thanks, guys, for the replies. I'm currently using APF as my firewall. Will look at CSF/LFD as an alternative. Also, if CPanel implements something to block IPs as they come in that would be great. Maybe block countries, even.

The failed logins stopped for a day or so but they've started again.
