There was a posting to the Full Disclosure mail-list yesterday by @kingcope in which he provided a script called killapache.pl that will cause a severe denial of service condition on Apache web servers. I had a chance to test out the script and can confirm that it will lock up an Apache server rather quickly. This blog post will highlight how the attack works and also the new rules that were just added to the OWASP ModSecurity CRS to prevent it.
