It then moves on to the fundamentals of implementing a protocol using the framework.  I talk about base requests, namespaces and tieing them together with factories with reference to Fuzzled::Protocol::HTTP, an example included in the framework. The paper also highlights a few tricks to the framework, including developing multi-threaded fuzzers, identifying offsets and parsing packets.  It ends  with my techniques to identify vulnerabilities highlighted by fuzzers.<\/p><\/blockquote>\n<p>You can download the paper here:<\/p>\n<p><!--adsense#New468--><\/p>\n<p><a href=\"http:\/\/www.nth-dimension.org.uk\/utils\/get.php?downloadsid=35\">WAFUTFF<\/a> [PDF]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad] If you remember we mentioned Fuzzled a little while back, the PERL fuzzing framework.
