This week, Simson Garfinkel tell us about his work on digital forensics.
 Note the unusual time and place: we meet on Monday at 10AM in MCS148.

The following week, our own Dimitris Papadopoulos will give talk at the
usual Wednesday 10AM timeslot.

Finding privacy leaks and stolen data with bulk data analysis and
optimistic decoding
Speaker: Simson L. Garfinkel, Associate Professor, Naval Postgraduate School
October 28, 2013, 11AM - 12

Modern digital forensics tools are largely based on the recovery and
analysis of files. This talk explores how identity information such as
email addresses, credit card numbers, and other of information can be more
efficiently found using bulk data analysis, and how results are
significantly improved through the use of optimistic decompression.
Together, these techniques can find important information on computer media
that are ignored by the majority of today's digital forensics tools.

This talk presents the results of a study of roughly 5000 hard drives
purchased on the secondary market and shows how different kinds of data
formats can be traced to different kinds of privacy leaks and coding
errors. It show how the results were generated using bulk_extarctor, an
easy-to-use open source digital forensics tool. Finally, it shows how
bulk_extractor was extended to detect data obscured with a simple
steganographic technique (XOR 255), and how a subsequence re-analysis of
the research corpus found significant use of the technique in commercial
software, malware, and by at least one computer criminal.

Simson L. Garfinkel is an Associate Professor at the Naval Postgraduate
School. Based in Arlington VA, Garfinkel's research interests include
digital forensics, usable security, data fusion, information policy and
terrorism. He holds six US patents for his computer-related research and
has published dozens of research articles on security and digital forensics.

Garfinkel is the author or co-author of fourteen books on computing. He is
perhaps best known for his book Database Nation: The Death of Privacy in
the 21st Century. Garfinkel's most successful book, Practical UNIX and
Internet Security (co-authored with Gene Spafford), has sold more than
250,000 copies and been translated into more than a dozen languages since
the first edition was published in 1991.

Garfinkel received three Bachelor of Science degrees from MIT in 1987, a
Master's of Science in Journalism from Columbia University in 1988, and a
Ph.D. in Computer Science from MIT in 2005.
