On February 25, Rafael Veras presented the results of his Masters research at the Network and Distributed Systems Security Symposium 2014, which took place in San Diego. The 15-page article, co-authored by Julie Thorpe and Christopher Collins is the first to show how semantic patterns extracted from publicly available password leaks can significantly improve the guessing performance of off-line attacks, exposing a security vulnerability. Rafael continues as a member of the vialab, currently in the first year of his PhD studies. He has been studying how data-centric measures of interestingness can be used to suggest relevant views of the data in visual analytics applications.
