Script Kiddies and 403, 404 errors
 

I;ve been using fail2ban for a long time. I thought I had all the bases covered. I've got jails for everything (I thought), but now there seems to be a whole new wave of idiots.

I have no idea what they are looking for, but does anyone out there know of a Fail2ban action script that can pick up this stream of 403 and 404 errors that these morons are producing? See sample below : -

I have no experience with fail2ban, but maybe something like mod_security which is an application firewall for webservers, is highly configurable, it can be made to look out for things like that, then take what action you tell it too

Joomla exploits mostly and quite old. The ones I searched for are 2009-ish and as such have been in the Snort Emerging Threats rule set for some time. The fact queries get a 403 or 404 is good but is a good sign but it's always better to ensure you're not running a stale installation or plugins of anything accessible through the web stack (in short: know what you run). If you're serious about blocking this, remember web servers see a lot of noise, then I agree anything that blocks (near-) real time would be more efficient than something that runs checks every n cycles, see http://blog.spiderlabs.com/2011/11/m...dentified.html for some leads.
