　　为加强计算机科学与工程学院与国外知名研究机构的学术交流，促进教师学术水平提升和研究生学术视野拓展，计算机学院定期邀请海内外知名学者来校讲座。

　　本次讲座邀请加州大学圣迭戈分校（UCSD）计算机科学与工程学院Geoff M. Voelker教授，来我校探讨互联网时代应用泛滥的技术因素和经济因素，欢迎感兴趣的教师和博士生参加。具体安排如下：

　　一、时间：2015年9月8日（周二），上午10:30-12:00

　　二、地点：清水河校区主楼B1-104

　　三、题目：Exploring the Technical and Economic Factors Underlying Internet Abuse

　　四、嘉宾：UCSD计算机学院 Geoff M. Voelker 教授

　　五、主持人：计算机学院 薛瑞尼 副教授

　　六：摘要：

　　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 direction shave evolved over time in response to them. I will then go into detail on work that our group has performed in an end-to-end analysis of the spam value chain as an example of a broader perspective on intervention in this space. 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 will characterize the modern spam ecosystem and results of interventions in the payment tier. I'll end by touching upon other kinds of Internet abuse that our group has studied from a similar perspective, and where our group is headed going forward.
