recently I've identified that some hack attempt was performed at one of my servers.

I have dumped nginx logs to github, please take a look and try to identify which tool was used to perform this attack.

Excerpt from log: - ktuser [04/Nov/2016:12:59:18 -0400] "POST /apply.cgi HTTP/1.1" 404 459 "-" "-" - ktuser [04/Nov/2016:12:59:18 -0400] "GET /cgi_bin/user_network_connection.asp HTTP/1.1" 404 459 "-" "-" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee" - - [01/Nov/2016:16:39:57 -0400] "HEAD HTTP/1.1" 404 0 "-" "Mozilla/5.0 Jorgee"

Full log can be seen here: https://gist.github.com/acosonic/772971fee7b4b20c5ba3da7657a42430

Also, please advice if there is some behavioural tool that would learn and identify that above is a threat, and ban such IP's.

  • Looks like a web vulnrability scanner (looking at that log, it could be any of them) has run a scan, the log format is your servers access log. – TheJulyPlot Nov 15 '16 at 16:33
  • I also own VPS, and similar kind of logs also do occur. This is basically a bot which is actually checking the Admin directories or Access-Manager directory of various services which you run on your server like PHPMyadmin, wp-admin for wordpress, /user/login for Joomla and so in. This is basically bruteforcing your juicy directories but it's not present so it gives 404 error. So, In case you have any unsecured login directory or any admin login of a service running. It's better to harden the credentials for the same – Gerorge Timber Nov 15 '16 at 18:19
  • @Gergrge Timber That part I figured immediately, and I'm asking which bot are they using...? And I'm also asking for advice for some behavioural analyses intrusion prevention tool. In this case rule would be 3 false scan = ban... – Aleksandar Pavić Nov 15 '16 at 21:20

    A Google search on "Mozilla/5.0 Jorgee" identifies which bot it is. As for how to respond, it really depends on your site and what is considered abnormal for your use cases. We can't know that for your server. – schroeder Nov 15 '16 at 22:09

    No need to note them all, just one ore two as it is working from a list. Just ban anything looking for PMA2012/pma2012 etc. as they have to be door knocking. – mckenzm Aug 28 '17 at 21:07
