[PHP] Blocking URL hacking attemps
I'm using a script called BlackHole that uses PHP and a hidden directory to catch bad bots and block them by their IP address from the site [http://perishablepress.com/blackhole-bad-bots/]. It's working very well, but I'd like to expand on the idea. When looking at our access logs, I see someone adding code to our URL's in hopes to, apparently, hack into our site. If our URL is like this: http://www.example.com/pages/bolts.php they are adding to it like this: http://www.example.com/pages/bolts.php/wp-content/themes/functions/thumb.php.cache/external_e19f4bb51bc2262e07d23b79b916c12c.php or http://www.example.com/pages/bolts.php/cart.php or http://www.example.com/pages/bolts.php/wp-content/themes/functions/thumb.phptimthumb.php or http://www.example.com/pages/bolts.php/bratislava/stare-mesto Is there a way that I can trap the extra info in the URL's and pass it to the BlackHole script to ban these attempts as well? I'm thinking I'll need to compare the entered URL with $_SERVER[PHP_SELF] and if there's extra info, like another *.php, after the page name, then ban the IP. I realize that's a rather simplistic explanation and there may be a better way to accomplish this. If anyone has any examples they can share, I'd really appreciate.

Not entirely clear what is meant by time table -- do you mean schedule of classes? Important dates in the school year? or...? Also, what is it you want to be able to do with this? Who will be using this? There are many different approaches one can take, depending on what needs to happen. Hard to know what to suggest without a little more info? I modified an application that was originally set up for scheduling conference rooms, my version was to schedule appointments at a convention. You can grab it at https://github.com/tamouse/cdmacal . It is probably *way* more complex than you need, but it might give some ideas? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you want to do more filtering, I would suggest coupling with fail2ban, so that filtering will occur at TCP level. -- RMA. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Examine the URL patterns and rewrite the URL appending to the string. This will allow you a little more control. I completely disagree on the blocking IP concept and this can lead to network latency and other issues, redirecting traffic is more efficient. I think the scare factor of products like black hole are really just that. Bots are not always a bad thing, when your server becomes more popular people are interested in content so controlling the bots is key. IP addresses can be spoofed and if you have an auto block this could be your undoing in the long run.
