Today I stepped into a new role as a Security Researcher for BreakingPoint Systems. I will be working with the team that handles the security component of the flagship product, the BPS-1000, which is a load and security testing appliance used to test network devices such as switches, firewalls, and the types of products my […]
I’ve been invited to speak at the Computer Security Institutes’s Annual Conference (CSI 2007) this November in Washington D.C., on the subject of VoIP Attacks. This presentation was originally intended to be a “state of the industry” type talk given every year or so, and the last time I gave it was at EUSecWest last […]
I’ve been invited to speak at ToorCon 9 in San Diego next month. My topic will be Context-keyed Payload Encoding in which I introduce a new method of keying an encoder which is based entirely on contextual information that is predictable or known about the target by the attacker and constructible or recoverable by the […]
Apparently, some guy purchased video of all of the DEFCON 15 talks on DVD, then ripped them all to MP4 and uploaded them to Google Video. If you couldn’t make DEFCON this year and wanted to see my talk, or don’t have the patience to read the 50 page paper but have about an hour […]
My paper detailing the research I presented last month at DEFCON 15 was published today in Uninformed Journal Vol. 8. The paper is entitled “Real-time Steganography with RTP” and details using steganographic techniques to establish a covert channel within the protocol commonly used for the media channel in VoIP calls as well as a reference […]
After reading this article regarding the state of the IDS/IPS market and how IDS systems still and will likely have their niche, I was reminded of the common problem that plagues both Information Security and the War on Drugs; the majority of the focus is on detection and policing rather than on prevention and treatment, […]
DEFCON 15, in their second year at the Riviera, seemed a little more settled than the turbulent vibe from last year. Unfortunately DEFCON already seems to be outgrowing this space as a couple of the talks I wanted to see were standing room only and attendees were spilling out into the halls. The badge this […]
BlackHat Briefings 2007 was a bit disappointing this year. This year, the first day of briefings had an entire track devoted to Voice Services. Being the sole VoIP researcher for TippingPoint’s DVLabs, I of course attended this entire track. In short, three words: waste of time. Out of 5 talks on VoIP security, I learned […]
I’ve been invited to speak at DEFCON 15 this August which is being held at the Riviera Hotel & Casino in Las Vegas. I’ll be presenting on some new research I’ve been working on involving VoIP and steganography. The presentation will be entitled “Real-time Steganography with RTP.”
A research paper that I recently authored entitled Mnemonic Password Formulas was published on Monday in Uninformed Journal Vol. 7. It’s essentially some research that I’ve done on the deficiencies in existing methods for memorability and manageability of passwords as well as documentation of a new method for the same that I’ve termed “Mnemonic Password […]
