This week we have a very full set of exciting talks.

On Monday at 11am, Geoff Voelker from UCSD give a CS colloquium on
measuring and mitigating Internet spam.

On Wednesday, Adam Smith from UPenn will give an introductory talk on
differential privacy at the Hariri Institute at 3pm.

On Friday we have the Privacy Edition of our bi-yearly Charles River Crypto
Day, with speakers Jon Ullman, Aaron Roth, Katrina Ligett, and Yanniv

CS Colloquium: Exploring the Technical and Economic Factors Underlying
Internet Spam
Geoff Voelker, UCSD.

Hariri Institute, MCS180
111 Cummington St, Boston MA

 The large-scale compromise of Internet hosts and services form a
 platform for supporting a range of criminal activity in the so-called
 Internet underground economy.  In this talk I will start by quickly
 surveying work that our group has performed over the past decade on
 the problems posed by these threats, and how our research directions
 have evolved over time in response to them.  In the remainder of the
 talk, I will go into detail on recent work that our group has
 performed in an end-to-end analysis of the spam value chain.  Using
 extensive measurements over months of diverse spam data, broad
 crawling of naming and hosting infrastructures, and product purchases
 from a wide variety of spam-advertised sites, I'll characterize the
 modern spam ecosystem including system infrastructure, business
 models, cost accounting, and consumer demand.  I'll end by
 characterizing the relative prospects for anti-spam interventions at
 multiple levels, initial results of interventions in the payment tier,
 and where our group is headed going forward.

 This work is part of a long-standing collaborative effort between
