Every other month the Honeynet Project releases a new forensic challenge.  These are captures of real attacks in the wild that the community can analyze, document and then submit for review.  This is an amazing chance to learn.  The Honeynet Project just released Forensic Challenge 5 - Log Mysteries. This challenge takes you into the world of virtual systems and confusing log data. Figure out what happened to a virtual server using all the logs from a possibly compromised server. Challenge 5 has been created by Raffael Marty from the Bay Area Chapter, Anton Chuvakin from the Hawaiian Chapter, and Sebastien Tricaud from the French Chapter. Submission deadline is September 30th and they will be announcing winners around October 21st.  The top three submissions are often awarded an autographed security book published by a member of the Project.
