A Telephony Revolution VoIP: Bridging the Gap Between Traditional and Network New CDP, CUCDM and Cisco Skinny modules and techniques of Viproy will be demonstrated in the workshop as well.Table of Contents Foreword Preface Audience Organization Software Conventions Used in This Book Using Code Examples Safari® Books Online How to Contact Us Acknowledgments Jim Van Meggelen Leif Madsen Jared Smith 1. In this hands-on workshop, attendees will learn about basic attack types for UC infrastructure, advanced attacks to the SIP protocol weaknesses, Cisco Skinny protocol hacking, hacking Cisco CUCDM and CUCM servers, network infrastructure attacks, value added services analysis, Cdr/Log/Billing analysis and Viproy VoIP pen-test kit to analyse VoIP services using novel techniques. The workshop contains live demonstration of practical VoIP attacks and usage of the Viproy modules. Furthermore, Viproy provides these attack modules in the Metasploit Framework environment with full integration. It has a dozen modules to test trust hacking issues, information collected from SIP and Skinny services, gaining unauthorised access, call redirection, call spoofing, brute-forcing VoIP accounts, Cisco CUCDM exploitation and debugging services using as MITM. Attacking VoIP services requires limited knowledge today with the Viproy Penetration Testing Kit (written by Fatih). Also the well-known attacks to the network infrastructure will be combined with the current VoIP vulnerabilities to test the target workshop network. ![]() ![]() This workshop includes basic attack types for UC infrastructure, advanced attacks to the SIP and Skinny protocol weaknesses, network infrastructure attacks, value added services analysis, Cdr/Log/Billing analysis and Viproy use to analyse signalling services using novel techniques. They can be hacked with legacy techniques, but a set of new attacks will be demonstrated in this workshop. ![]() Signalling protocols are the centre of UC environments, but also susceptible to IP spoofing, trust issues, call spoofing, authentication bypass and invalid signalling flows. This workshop is designed to demonstrate these cutting edge VoIP attacks, and improve the VoIP skills of the incident response teams, penetration testers and network engineers. VoIP attacks have evolved, and they are targeting Unified Communications (UC), commercial services, hosted environment and call centres using major vendor and protocol vulnerabilities. ![]()
