Google Tech Talk September 10, 2009 ABSTRACT Presented by Richard A. Kemmerer. Botnets, which are networks of malware-infected machines that are controlled by an adversary, are the root cause of a large number of security threats on the Internet. A particularly sophisticated and insidious type of bot is Torpig, which is a malware program that is designed to harvest sensitive information (such as bank account and credit card data) from its victims. In this talk, we report on our efforts to take control of the Torpig botnet for ten days. Over this period, we observed more than 180 thousand infections and recorded more than 70 GB of data that the bots collected. While botnets have been hijacked before, the Torpig botnet exhibits certain properties that make the analysis of the data particularly interesting. First, it is possible (with reasonable accuracy) to identify unique bot infections and relate that number to the more than 1.2 million IP addresses that contacted our command and control server during the ten day period. This shows that botnet estimates that are based on IP addresses are likely to report inflated numbers. Second, the Torpig botnet is large, targets a variety of applications, and gathers a rich and diverse set of information from the infected victims. This allowed us to perform interesting data analysis that goes well beyond simply counting the number of stolen credit cards. In this talk we will discuss the analysis that we performed on the data collected ...

Google Tech Talk May 4, 2010 ABSTRACT In this talk, we present the main features of Newspeak, a dynamic programming language focused on software engineering. All names in Newspeak are late bound - including class names. Hence all classes in Newspeak are virtual, every class declaration defines a mixin, and class hierarchy inheritance comes for free. Newspeak has no global namespace and no static state. Top level classes act as module definitions. These have no external dependencies. Each instance of a top level class is a module that runs in its own sandbox in accordance with the object capability security model. Gilad Bracha is the creator of the Newspeak programming language. Previously, he was a Distinguished Engineer at Cadence, and a Computational Theologist and Distinguished Engineer at Sun. He is co-author of the Java Language Specification, and a researcher in the area of object-oriented programming languages. Prior to joining Sun, he worked on Strongtalk, the Animorphic Smalltalk System. He received his B.Sc in Mathematics and Computer Science from Ben Gurion University in Israel and a Ph.D. in Computer Science from the University of Utah.
