Recently, one of my server’s IP is listed in Spamhaus DBL, due to some malware present in the server. So as it is a test server I don’t much worried about that, but still interested to get some knowledge that how to deal with these type of threats?
Also, opensource projects like Rkhunter, ClamAV, is it capable enough to detect the malware?
And lastly, how this malware is present in the server, what should I do to avoid it?
Thanks in advance.
