Endrun—Secure Digital Communications For Our Modern Dystopia
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.

Voyeurism in the Air
Lockdown - Madison, WI
New updates to the CreepyDOL system, including a large-scale deployment in Montezuma, NM with 755 devices. Redux of Paranoia presentation at the request of the Lockdown conference organizers.
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. How can we do this? The laziness of untold developers—and we use this simple idea to pass our low, low prices (and open source software) on to you! 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!

The Perfectly Legitimate Project
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
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
DEF CON - 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, 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!

CreepyDOL: Cheap, Distributed Stalking
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
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
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
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.
