The Stuxnet computer worm is perhaps the most complicated piece of malicious software ever built - roughly 50 times the size of the typical computer virus. This threat leveraged a huge array of new techniques to spread itself, conceal itself and to attack Iranian nuclear enrichment centrifuges. This talk will provide a detailed dissection of the Stuxnet worm, answering such questions as how it spread, how it evaded detection, what it did once it found its target, and ultimately, how successful it was.

     Vast resources are devoted to predicting human behavior in domains such as economics, popular culture, and national security, but the quality of such predictions is usually poor. It is tempting to conclude that this inability to make good predictions is a consequence of some fundamental lack of predictability on the part of humans. However, our recent work offers evidence that the failure of standard prediction methods does not indicate an absence of human predictability but instead reflects: 1.) misunderstandings regarding which features of human dynamics actually possess predictive power, and 2.) the fact that, until recently, it has not been possible to measure these predictive features in real world settings.
 
     This talk introduces some of the science behind this basic observation and demonstrates its utility through three case studies. We begin by considering social groups in which individuals are influ- enced by the behavior of others; in these situations, social influence is known to decrease the ex ante predictability of the ensuing social dynamics. We show that, interestingly, these same social forces can increase the extent to which the outcome of a social process can be predicted in its very early stages. This finding is then leveraged to design prediction methods which outperform existing techniques for predicting social group dynamics.
 
     The second case study involves analysis of the predictability of adversary behavior in the coevo- lutionary “arms races” that exist between attackers and defenders in many domains, including cyber security, counterterrorism, fraud prevention, and various markets. Our analysis reveals that conventional wisdom regarding these coevolving systems is incomplete, and provides insights which enable the development of proactive cyber defense methods that are much more effective than standard techniques. Finally, we consider the task of predicting human behavior at the level of individuals. In particular, we show that a given individual’s mobility patterns can be predicted with surprising accuracy, and conversely that knowledge of even a small portion of a person’s travel patterns permits reliable identification of that individual.

There are currently 60 nuclear reactors under construction worldwide with nearly half of these projects being built in China. There is no doubt that East Asia is emerging as a leader in the international nuclear community where China and the Republic of Korea (ROK) are playing major roles as a result of their aggressive new plant build programs. Both China and South Korea present very interesting case studies where the former is rapidly building up domestic expertise in nuclear construction while the latter has gone one step further in capitalizing successfully on a nuclear export business. Both countries have relied heavily on external commercial support in building up this expertise. In the case of South Korea, the “Koreanization” of nuclear power took place in the 1980’s and 1990’s, first with a large number of Western builds and ultimately a complete indigenization of pressurized water reactor technology through a technology transfer with Combustion Engineering. The Chinese domestic nuclear program has been largely influenced by Western vendors as well; however, there has been significantly less emphasis on exporting the technology up to now as they master the imported technologies for their domestic program. The recent AP1000 technology transfer between Westinghouse Electric Company and China has opened up unique transnational learning opportunities between the United States and China where the lessons learned building the first AP1000 plants in China will be shared with the two U.S. utilities now embarking on new plant construction at the Vogtle and V.C. Summer sites, in Georgia and South Carolina, respectively. This talk will review both the historical experiences of exporting nuclear technology to the ROK and China, as well as the progress being made by these countries in absorbing the technology. Further, the AP1000 passive plant technology will be summarized as an example of the general trend for future designs in response to the reactor accidents at Fukushima Dai-ichi in March 2011. Finally, the advanced construction techniques being used to build AP1000 plants in both the U.S. and China will be highlighted along with their benefits in delivering new plants on schedule.

The collision between the Iridium 33 and the Cosmos 2251 shows space debris is becoming a significant threat to satellites. Concerns of the threat led to the IADC space debris mitigation guidelines. However, there is no way to compel or enforce compliance with the guidelines, and since implementing some guidelines can be expensive, they are
frequently not followed. Moreover, the current legal framework is unable to determine who is liable for losses in an on-orbital collision. A space surveillance data sharing committee is proposed to solve the liability problem. Under the proposed liability rules, satellite operators would be liable for the debris they created. Insurance companies will step in to cover such risk. Therefore, there would be a financial incentive for them to adopt the debris mitigation
guidelines.


About the speaker: Ting Wang is a postdoctoral fellow at CISAC. His research concerns on space debris problems, and ASAT weapons. Before coming to CISAC in 2011, he was a postdoctoral fellow at the Judith Reppy Institute for Peace and Conflict Studies at Cornell University. He received a PhD at the Beihang University in China. His PhD dissertation was titled "Orbital Debris Evolution and Threat to Spacecraft."

He also holds a B.A. in aerospace engineering from Beihang University and has worked at the Shanghai Institute of Satellite Engineering. He was a visiting scholar at the Union of Concerned Scientists in 2003, where he began to be interested in security issues.

The book The Soviet Biological Weapons Program: A History by Milton Leitenberg and Raymond A. Zilinskas is scheduled to be published on May 14, 2012 by Harvard University Press. This book describes and analyzes in detail the Soviet biological warfare (BW) program, from its inception in 1928 to likely termination in 1992. The two most vexing questions that the authors attempt to answer are; in the final analysis, what were the Soviet BW program’s accomplishments? Second, might Soviet accomplishments related to enhancing biological weaponry be made available to future national or terrorist BW programs? This presentation will explain why these questions are difficult to answer but nevertheless will propose answers to them. The authors have a basis for doing so because they have been able to collect and analyze information from primary resources in archives and special collections, as well as in the course of hundreds of hours spent on interviewing scientists who operated the Soviet BW program. During his presentation, Zilinskas will discuss tentative findings that encompass subjects such as whether the application of genetic engineering, which resulted in among other accomplishments the development of multiantibiotic resistant Bacillus anthracis, Francisella tularensis, and Yersinia pestis, actually resulted in improved weaponry and whether genetically engineered strains remain in Russian cell culture collections and from there might escape or be made available to those who seek to acquire biological weapons.


About the speaker: Raymond A. Zilinskas, formerly a clinical microbiologist, is the director of the Chemical and Biological Weapons Nonproliferation Program at the Center for Nonproliferation Studies of the Monterey Institute of International Studies. He is the editor of Biological Warfare: Modern Offense and Defense (Lynne Rienner, 1999) and co-editor of the Encyclopedia of Bioterrorism Defense (Wiley, 2005). He received a PhD from the University of Southern California and a BA in Biology from the University of Stockholm.

The U.S.-North Korean “Leap Day” deal of February 29 was thrown into question by the North’s recent announcement of a satellite launch between April 12 and 16 to celebrate the centenary of Kim il Sung’s birth. As the opening of the launch window nears, an intense international brouunfolds with, amazingly, the US, Russia, China, Japan, and South Korea on the same page, dead set against a launch; and an isolated North Korea defiantly planning to celebrate the centenary with a satellite launch on or by April 15. In this presentation, the three speakers will provide a brief background of the successes and failures of North Korea’s previous satellite launches (score: 0 for 3 by Western count, 2 for 2 by DPRK count) and what has been learned from these; an expected timeline of activities of the countdown; and a guide and comparison of the new Sohae Western launch complex to the older Tonghae Eastern launch complex.

About the topic: What could queueing theory, the science of customer flows and delays in service systems, possibly offer towards understanding and countering terrorism? In terror queue models, newly hatched terror plots correspond to newly arriving customers, the number of ongoing terror plots corresponds to the queue of customers waiting to receive service, undercover agents or informants correspond to service providers, customer service is initiated when a terror plot is detected, and service is completed when the plot is interdicted. Not all plots are interdicted; successful terror attacks correspond to customers who abandon the queue without receiving service! Building upon these ideas, we will focus our attention upon a simple observation: other things being equal, the number of ongoing terror plots increases with the duration of time from plot initiation until execution or interdiction (whichever comes first), yet no estimate of the probability distribution governing terror plot duration has appeared in the open literature. Starting with a review of US terrorism-related indictments, lower and upper bounds for the initiation date of 30 distinct Jihadi plots were identified in addition to the date of arrest or an attempted/actual terror act. Accounting for the censoring and truncation effects inherent with these data; the estimated mean duration equals 9 months, while 95% of all plots are estimated to fall between 1 and 25 months. These estimates suggest that in the United States, on average approximately three ongoing Jihadi terror plots have been active at any point in time since 9/11/2001.
