Our server has just been hacked few days ago, we made a complete backup of it, but, from that time, we get erros while trying to access our websites hosted on it : some times, everything works perfectly, and then when we refresh the page, we get an error message :

Internal server error

Where could that come from ?

You need to completely rebuild the server. See…. – Kyle Smith Apr 5 '12 at 15:13
Read the logs, they'll tell you why it's erroring. – womble Apr 5 '12 at 15:24
Ask the admin :-) – mfinni Apr 5 '12 at 15:31
Please tell me you made a complete backup before you were hacked, because otherwise your backup cannot be trusted. – Jeff Welling Apr 5 '12 at 16:26
Yes sure, the backuo seemed to be all right – Miles M. Apr 5 '12 at 17:40

Check the logs. The answer is there:

  • Apache Logs
  • Lighthttp logs: /var/log/lighttpd
  • Some nginx logs
  • Linux Logs:
    • /var/log/message
    • /var/log/auth.log
    • /var/log/kern.log
    • /var/log/secure
    • /var/log/yum.log
  • MySQL logs: /var/log/mysqld.log
