Today, you create an account for every site or mobile app you visit, in effect becoming a citizen of that company. And like most communities, growth of the user account base is critical to succeeding. Users both contribute content (e.g., reviews, pins, and posts) and are a channel for monetization (e.g., ad clicks, promotions, and in-app purchases). However, some visitors to this community are unwelcome—well-organized crime rings are creating so-called sleeper cells, fake user accounts masquerading as normal citizens hiding among billions of users, and waging large-scale attacks to exploit these services for financial gain.
Using analysis of more than 500 billion events and 400 million user accounts from global online services over the past year, Yinglian Xie exposes the issue of global sleeper cells, providing an in-depth analysis of sleeper cells’ characteristics, the sophisticated attack techniques being used to wage war, and how to mitigate attacks using Spark’s in-memory big data security analytics.
Yinglian Xie is the CEO and cofounder of DataVisor, a startup in the area of big data analytics for security. Yinglian has been working in the area of internet security and privacy for over 10 years and has helped improve the security of billions of online users. Her work combines parallel-computing techniques, algorithms for mining large datasets, and security-domain knowledge into new solutions that prevent and combat a wide variety of attacks targeting consumer-facing online services. Prior to DataVisor, Yinglian was a senior researcher at Microsoft Research Silicon Valley, where she shipped a series of new techniques in production. She has been widely published in top conferences and served on the committees of many of them. Yinglian holds a PhD in computer science from Carnegie Mellon University.
