Blue Box: The VoIP Security Podcast

Blue Box ETel2006 Podcast #1: Phil Zimmermann presentation

Synopsis: Presentation by Phil Zimmerman at O'Reilly's Emerging Telephony Conference on January 26, 2006

---

Welcome a special edition of Blue Box: The VoIP Security Podcast from the floor of the Emerging Telephony Conference in San Francisco, CA.  In this presentation, Phil Zimmermann, creator of PGP, outlines his ideas and plans for a new way to encrypt VoIP conversations.  His new software, currently called "zFone", will be available in early March for beta testing.  Updates and information will be available from his website at http://www.philzimmermann.com/.  A quote:

I would like to do for VoIP what I did for e-mail... I'd like to make it possible for you to whisper in someone's ear - even if their ear is thousands of miles away.

We thank Phil Zimmermann and the great team at O'Reilly for giving us permission to make this recording available to you all.

• 02:05 - Feature interview with Shawn Merdinger,  a security researcher now employed by the Tipping Point division of 3Com.  He was previously a security researcher at Cisco and as an independent security researcher started an investigation into the security of WiFi handsets.

  On the weekend of January 13-15, he attended Shmoocon 2006, a hacker conference in Washington, DC, and presented a talk entitled “VoIP WiFi Phone Handset Security Analysis: We’ve met the enemy…and they built our stuff?!?” (his Shmoocon presentation is available for download here)  Following that, on Monday, January 16, 2006, he released advisories to the ‘full-disclosure’ mailing list outlining the vulnerabilities that he found in six SIP WiFi handsets:

  • ACT P202S VoIP wireless phone multiple undocumented ports/services
  • Senao SI-7800H VoIP wireless phone wdbrpc debug service UDP/17185
  • Clipcomm CPW-100E VoIP wireless handset phone open debug service TCP/60023
  • MPM HP-180W VoIP wireless desktop phone undocumented port UDP/9090
  • ZyXel P2000W (Version 2) VoIP wireless phone undocumented port UDP/9090
  • Clipcomm CP-100E VoIP wireless desktop phone open debug service TCP/60023
  
  We spoke with Shawn at length in a wide-ranging interview that covered topics such as:
  • Background - why did he start the project?
    
  • Vendor notification program
  • Future plans for further testing?  Methodology?
  • A POP e-mail client on a SIP phone?
  • Test methodology?  Access to manuals?
  • Implications for users of WiFi phones
  • Reactions from affected vendors
  • Summary of vulnerabilities
  • Timeframe for next release?
  • Advice to companies for working with independent security researchers
  • Business opportunities around helping companies work with security researchers
  • Applying this research to the VoIPSA Threat Taxonomy
  • What people and companies can do to help in his research
  • 30:38 - End of interview
  
  It was quite an enjoyable interview and we commend Shawn for the responsible manner in which he is interacting with vendors and his efforts to educate others about doing the same.  If you would like to assist Shawn in his efforts, by for instance providing WiFi phones for testing, Shawn can be reached at [email protected].

Call for Papers: Third Annual VoIP Security Workshop, Berlin, Germany, June 2006

Dorgham Sisalem recently posted to the VOIPSEC mailing list this Call for Papers for the Third Annual VoIP Security Workshop on June 1 and 2 in Berlin, Germany. As the page says:

While the standards and products for VoIP services have reached market maturity, security and regulatory aspects of such services are still being discussed. The aim of the VoIP Security Workshop is to serve as a platform for researchers and visionaries from academia, research labs, industry and government from all over the globe to share their ideas, views, results, and experiences in the field of VoIP and IMS security and regulation. The Third VoIP Security Workshop will include presentations of theoretical and experimental achievements, innovative security systems, prototyping efforts, case studies, and advancements in technology directly affecting VoIP and IMS services.

Submission deadline is February 28th. It sounds like an interesting workshop... I may have to very well see if I can get there. (Added bonus for me... Berlin is a great city and I get to practice mein Deutsch!)

Though we tried very hard to connect (including planning to do the show with Jonathan calling in from an airport), Jonathan was travelling again this week and so Dan was solo again. This show does feature a 19-minute interview with Mark Collier, CTO of SecureLogix.

Show Content:

Detailed show notes will be available soon.  Due to the fact that I (Dan) am travelling tomorrow, I'm loading the show up here for listeners.  Show notes should appear late Wednesday night.

I will note that at approximately 22:10 I begin a very interesting 19-minute interview with Mark Collier, CTO of SecureLogix.  With 20 years experience in the field, Mark brings a wealth of expertise to the conversation, which ranged over topics such as the current state of VoIP security, standards, Skype, new projects, and Mark's dire prediction for 2006.  Well worth a listen.

Also, as a holiday bonus - and because podcasts all over the Internet are participating in this effort, after the regular show outro around 47 minutes, the show includes the UNICEF-benefit song "If Every Day Were Christmas" created by Podsafe for Peace, a collaboration of 32 artists in 9 countries very much along the lines of the "We Are The World" effort back in 1985 - only this time the artists did not physically meet and it was all put together digitally.  If you have not heard it yet, it is well worth a listen.
