VoIP Wars and the Awesome Audience

Last year, was my first DEF CON presentation “VoIP Wars: Return of the SIP.” I really enjoyed being a part of this amazing security conference. I presented some next generation VoIP attacks such as SIP trust hacking, SIP proxy bounce attacks and attacking mobile applications through the SIP protocol. I also announced my security assessment tool Viproy VoIP penetration testing kit during the security conference.

VoIP Wars: Attack of the Cisco Phones

I have shared my Cisco based hosted VoIP networks security research at Blackhat USA 2014 and DEF CON 22 last week. This research contains several different attack vectors, published vulnerabilities, unpatched vulnerabilities, Skinny protocol attacks, new SIP protocol attacks, VOSS IP phone XML services attacks and new version of Viproy VoIP penetration testing kit. I'll prepare a few detailed blog entries for them, before this, you can review the slide set and the recap of the live demos of the presentation.

My presentation is below, VoIP Wars: Return of the SIP and you can get Viproy from www.viproy.com. I'll share my USA experience in this blog entry, my plans about Viproy and its new modules/features will be explained in an another blog entry. 

Blackhat Arsenal USA 2013

Viproy VoIP Penetration Testing and Exploitation Kit is accepted for Blackhat Arsenal USA 2013. It will be amazing for me, I will present it at Las Vegas, USA. Blackhat Arsenal USA 2013 line up is announced and many good tools are waiting for us. You can check all tools and author via this Blackhat Arsenal USA page.

Line up contains many cool tools. My favorite tools are armitage, dalvik inspector, drozer, gotbeef, hookme, smartphone pen-test framework, set and vega. They have created an author page for me, I liked it :-)

I'm working on a few modules for Viproy and I'm planning to announce them at Blackhat Arsenal USA 2013. SIP Message support, DDOS via SIP servers and MITM Fuzzing modules are coming.
