De-Anonymizing Bitcoin One Transaction at a Time

1400, Noether
Speaker(s): David Décary-Hétu, Mathieu Lavoie
Bitcoin is an established virtual currency well known for enabling affordable and efficient transfers of money between individuals and entities. With its market cap of over $7 billion and hundreds of thousands per day, the Bitcoin currency has become popular enough for offenders to be able to hide among its users when they purchase illicit goods and services online or need to receive extortion payments. The aims of this presentation are twofold. The first is to present an open-source tool developed by the panelists that analyzes all of the Bitcoin transactions and regroups Bitcoin addresses based on their incoming and outgoing transactions. This allows for a more accurate mapping of individuals' online activities no matter how many Bitcoin addresses they are using. The tool, as well as a database of all nodes identified by the tool, will be released on the day of the conference. The second aim of this presentation is to provide real world use cases for the tool to better understand online illicit activities. To do so, David and Mathieu will present two case studies that will follow the evolution through time of the revenues generated by online illicit groups and the strategies they used to manage the incoming bitcoins. This talk will be of interest to attendees looking to better understand how the Bitcoin currency works and the attacks that can be used to de-anonymize Bitcoin users. A live demonstration will explain how the open-source tool works and the strategies that could be used to preserve one's anonymity in the Bitcoin network.


Is the Brain the Next Hackable Driver?

1400, Friedman
Speaker(s): Ellen Pearlman
Do our EEG, fMRI, and other biometric data contain the essence of who we are and what we think? In the future, could this data be used as an identifier for security and thought modification as well as exploring virtual worlds? If our "brainotypes" or "brain fingerprints" and concurrent cognitive processes are monitored, how do we prepare for this looming horizon? Though no one is entirely sure, these questions invite both scientific and metaphorical approaches addressing these issues. Ellen will discuss the emergence of technologies, research, and methods on brain datatyping; privacy and its ethical implications; sending and receiving motor commands between two different brains; moving robotic prosthesis through thoughts; the formation of memory; manipulating memory via frequencies of light; and hacking brain computer interfaces (BCIs) to extract vital information. Keeping these methods and techniques in mind, she will also show a brief excerpt from her own creation "Noor - a Brain Opera" which asks the question "Is there a place in human consciousness where surveillance cannot go?"


The Panama Papers and the Law Firm Behind It: Shady Lawyers Caught With Their Pants Down

1400, Lamarr
Speaker(s): Alexander Urbelis, Manos Megagiannis
The Panama Papers are beyond question one of the most significant acts of whistleblowing next to the Snowden revelations. Yet, the full measure of what has been leaked remains to be disclosed to the public, raising considerable questions about what happened, who is implicated, and the legal and illegal acts of Mossack Fonseca, the law firm behind the breach. This talk will review what the Panama Papers leak is, introduce the breached law firm, examine Mossack Fonseca's explanation of the breach, deconstruct and debunk their explanation, present MF systems that were more likely the cause of the breach, present alternative and more plausible theories of the breach, examine MF communications that indicate questionable and possibly illegal activity within and without the United States, step through the legal implications of MF's activities, identify the right Infosec questions clients should be asking of law firms, and provide a question and answer session to ruminate about the breach and its source.
