Thread: Denial of Service Attack

  1. #1

    Denial of Service Attack

    Sorry for the slow server / "Server Busy" issues this afternoon. I've only just had a chance to have a proper look at it and it turned out to be some sort of site scraping or denial of service attack. Basically a bot based in Serbia was hammering the site loading hundreds of pages at the same time.

    I've banned the originating IP address at the firewall and the server load came straight back down to normal. Hopefully they'll get the hint and 'eff off now!

    Just looking at it a bit more it looks like a brute force attempt to find a vulnerability rather than an attempt to push the site offline. The logs are full of thousands of SQL injection attempts etc. It was basically trying every known vulnerability against every page on the site.

    Annoying for a while, but they didn't get in.

    Code: - - [28/Feb/2014:12:05:59 +0000] "GET /showthread.php/1354-Black-Death-my-memory/page2?p=if(now()%3dsysdate()%2csleep(6)%2c0)/*TP/1.1"  - - [28/Feb/2014:12:06:00 +0000] "GET /showthread.php/1354-Black-Death-my-memory/page2?p=(select(0)from(select(sleep(9)))v)/*'% - - [28/Feb/2014:12:06:00 +0000] "GET /showthread.php/1552-Last-chance-to-vote/?mode=%5c&p=16163

    I thought the SD was a bit too popular for 4.30 on a Friday afternoon when we are obviously busy getting on with our work.
