Security by Consent; or, Peel's Principles of Security Operations
October 18, 2016
SecTor - Toronto, ON, Canada
November 2, 2016
O'Reilly Security New York - New York, NY
November 10, 2016
O'Reilly Security Amsterdam - Amsterdam, Netherlands
How to create and maintain a security operation within a larger organization that focuses on cooperation and consent, rather than coercion, based upon the 'policing by consent' model created in 1820s England.
Are you tired of knowing everything, having people ignore 'the security person' because 'reasons,' and then having 'I told you so' as your only comfort? Sick of the hostile relationship between security and development, security and operations, security and HR, and/or security and everyone not wearing a black t-shirt? There’s a better way. Faced with the challenge of building a security function into a society that wasn’t sure it wanted one (but which nonetheless needed it), Charles Rowan and Richard Mayne set out what became known as the Peelian Principles of Policing, or Policing by Consent. They provide an effective model for running a security group that stands with its organization, rather than against it. We are, after all, 'only members of the public who are paid to give full-time attention to duties which are incumbent on every citizen in the intent of the community welfare.' Join us to become a security Bobby—where a commitment to service is non-optional, but the silly hat’s only needed if you like it.
Don't Be a Hero
October 31, 2016
Ignite O'Reilly Security - New York, NY
October 29, 2016
PumpCon - Philadelphia, PA
Ignite format; presentation on the value of compliance for small and mid-sized businesses. The talk was designed to lay out the motivational case, rather than the step-by-step implementation of compliance in an organization.
Swinging swords, slaying beasts, drinking Red Bull, and coding through a weekend: the life of a startup is exciting and free from rules. When you get your first security audit and have to establish policies and compliance, you may find your sword hand itchy; are the good times over? No--something even better comes next. Stop being a hero-based organization, and build things that will outlive you.
Endrun—Secure Digital Communications For Our Modern Dystopia
October 17, 2014
Black Hat Europe - Amsterdam, Netherlands
With Grant Dobbe. Censorship-resistant communications based on the Delay-Tolerant Networking concept.
The Internet is no longer trustworthy, having been compromised by bad actors across the globe. Current proposals to work around a compromised Internet rely upon encrypted transport links, mesh networks, or harassing users for being unable to use GPG safely. Each of these strategies fails in different ways that inevitably lead to information leakage or -- in the extreme case -- death. Endrun, by contrast, takes NASA's Disruption-Tolerant Networking project from a laboratory experiment to a functional system that supports user-friendly encryption in hostile environments. Endrun embraces the nearly-unlimited throughput of a disk-laden station wagon and creates a reliable, eventually-consistent communications system ideal for activists, refugees, and trolls.
The Perfectly Legitimate Project
April 25, 2014
ThotCon - Chicago, IL
With Grant Dobbe. Cryptographically-sound user-friendly darknet designs.
When we can't use the Internet anymore---either because it's gone, or because we can't trust it---how can we share our cat GIFs, tear gas remedies, or recipes for Roasted Rodent Ratatouille? The Perfectly Legitimate Project creates a decentralized, Internet-optional system of sharing data among a group of nodes without relying on easy-to-locate mesh networks. PLP uses whatever’s available to move heavily-encrypted payloads around, including short-range wireless communications (on license-free VHF, UHF, ZigBee, or WiFi), sneakernet, or tasty (and nutritious!) carrier pigeons. PLP has four components: NATASHA and MOOSE provide user-friendly services (such as email, wikis, and blogs) to any end-user without a need for specialized hardware or customized software, while BORIS and SQUIRREL let couriers use any means necessary to ship data with a derivative of the interplanetary Disruption-Tolerant Networking protocol. The end result is a system that's OPSEC-capable, easy to use, and can be deployed when zombies attack---or when you're just tired of having your adversaries listen through the fillings in your teeth.

War Crimes as a Service
October 26, 2013
PumpCon - Philadelphia, PA
With Dr. John Linwood Griffin. Introduction for non-lawyers to the Tallinn Manual, why security experts should care, and a modest proposal for how to stop unlawful digital warfare.
Three years of international negotiations and deliberations by eleven lawyers, two academics, a bunch of editors, and an Estonian dog named Terry gave us the 'Tallinn Manual'---a.k.a., cover for the world’s militaries to blow up the Internet. This talk will explain why international law matters, why it’s important that a bunch of non-hackers defined 'attack' to only mean dead bodies, and how we can prevent certain nations from clogging the tubes with the blood of the innocent. The international law of war isn’t dead---it’s just sleeping. Come help wake it up.
Stalking a City for Fun and Frivolity
August 3, 2013
DEF CON - Las Vegas, NV
October 24, 2013
LASCON - Austin, TX
Distributed sensor network data acquisition, filtering, and visualization, with several security applications. This presentation addressed the architecture and collection aspects of the CreepyDOL system, as well as the implications for global surveillance states and engineering as a profession.
Tired of the government being the only entity around that can keep tabs on a whole city at once? Frustrated by dictators du jour knowing more about you than you know about them? Fed up with agents provocateur slipping into your protests, rallies, or golf outings? Suffer no more, because CreepyDOL is here to help! With open-source software, off-the-shelf sensors, several layers of encryption, and a deployment methodology of 'pull pin, point toward privacy insurance claimant,' it allows anyone to track everyone in a neighborhood, suburb, or city from the comfort of their sofa. For just four easy hardware purchases of $131.95, you, too can move up from small-time weirding out to the big leagues of total information awareness: deploy CreepyDOL today!
CreepyDOL: Cheap, Distributed Stalking
August 1, 2013
Black Hat USA - Las Vegas, NV
Distributed sensor network data acquisition, filtering, and visualization, with several security applications. This presentation addressed the architecture and collection aspects of the CreepyDOL system.
Are you a person with a few hundred dollars and an insatiable curiosity about your neighbors who is fed up with the hard work of tracking your target's every move in person? Good news! You, too, can learn the intimate secrets and continuous physical location of an entire city from the comfort of your desk! CreepyDOL is a distributed sensing and data mining system combining very-low-cost sensors, open-source software, and a focus on user experience to provide personnel identification, tracking, and analysis without sending any data to the targets. In other words, it takes you from hand-crafted, artisan skeeviness to big-box commodity creepiness, and enables government-level total awareness for about $500 of off-the-shelf hardware.
Reticle: Dropping an Intelligent F-BOMB
July 26, 2012
Security BSides Las Vegas - Las Vegas, NV
Software to control ad-hoc networks of disposable computers.
F-BOMB is a disposable computing project, and Reticle is its software brain: a distributed, leaderless system for transferring data and commands to and from the tiny, distributed, dirt-cheap little boxes. Together, these two systems form a botnet-styled sensor network that can be deployed the same way as a smoke grenade by a field agent, but with intelligent encryption, plausible deniability, and a peer-to-peer command network to ensure that an enemy can't compromise your goals-- whether you're providing Internet access to an Occupy group, or playing distributed hide and seek for cell phones. We discuss the design and implementation of Reticle, which was intended to take some of the networking ideas from modern botnets and apply them in a more useful context. Reticle was created with support from DARPA Cyber Fast Track, and the code, utilities, and documentation created under that project will be released with the talk.
Sacrificial Computing for Land and Sky
January 27, 2012
ShmooCon - Washington, DC
Hardware design for very-low-cost sensor nodes.
Projects such as the incredible Wireless Aerial Surveillance Platform give you the ability to monitor or attack networks far from accessible areas, but are limited by their deployment characteristics: $6000+ buys you just 10-30 minutes on target, and you have simultaneously to do your work and defend the physical plane from Bad Men With Projectile Weapons, lest they take exception to your plans. Disposable computing designed for just one use can provide massive reductions in cost and time to deployment without sacrificing flexibility; we show how $50-$75 can give you upwards of 24 hours to work on a task, while using only off-the-shelf hardware, and leaving no data onsite for an adversary to analyze after the operation. These computers can then be planted manually, or even dropped from unspecialized UAVs (such as the Parrot Drone) to allow your expensive plane to return to safety while you do your work.
Mnikr: Reputation Construction Through Human Trading of Distributed Social Identities
November 13, 2009
5th ACM Workshop on Digital Identity Management - Chicago, IL
With Dr. John Linwood Griffin. Stock-market-like construction of computer-readable human-mediated reputation scores. Selected as the best paper at the workshop.
Reputation forms an important part of how we come to trust people in face-to-face interactions, and thus situations involving trust online have come to realize that reputation is an important characteristic in the digital age. We propose a new holistic and context-free approach to quantifying reputation on the Internet, based upon a stock exchange where users can trade reputation shares of other users and obtain goodwill dividends, including new algorithms for identifying and creating digital identities not inherently tied to a user’s personally identifiable information. We developed such a system, named Mnikr, and deployed our system on the Internet for a month to demonstrate and evaluate this approach. Our results suggest that existing public data sources can indeed be used to create an overarching social network whose utility is greater than its number of users would indicate, and in which reputation measurements are generated that are actually indicative of each user’s standing in society.
