Ejovi Nuwere and Mikko Varpiola: The Art of SIP fuzzing and Vulnerabilities Found in VoIP

Black Hat Briefings, Las Vegas 2005 [Audio] Presentations from the security conference

This presentation will cover SIP and VoIP related automated fuzzing techniques. Using real world vulnerabilities and audit engagements we will give a technical understanding of this emerging technology and its common attack vectors. The techniques discussed in this talk will not only be limited to SIP but will apply to methodical audit approaches for fuzzing text based protocols which can be more complex then fuzzing binary protocols. This talk will include: * 0 day vulnerabilities (or one day) * Example fuzzing scripts * Proof of concept code Ejovi Nuwere is the founder of SecurityLab Technologies. Nuwere gained media attention and international recognition for his highly publicized security audit of Japan's National ID system--JukiNet. Nuwere is the Chief Technology Officer of SecurityLab Technologies where he heads the companies VoIP security auditing group. He currently lives in Boston and is working on his second book, Practical Penetration Testing (O'Reilly). Mikko Varpiola is the head of test tool development at Codenomicon. His specific area of expertise is in anomaly design - e.g. what to feed into software to make it fail. Before Codenomicon he worked as a researcher in the acclaimed PROTOS project at Oulu University Secure Programming Group (OUSPG).
