Hey all,
I've just posted a new tool and paper for Oracle forensics. The tool, orablock, allows a forensic investigator to dump data from a "cold" Oracle data file - i.e. there's no need to load up the data file in the database which would cause the data file to be modified, so using orablock preserves the evidence. Orablock can also be used to locate "stale" data - i.e. data that has been deleted or updated. It can also be used to dump SCNs for data blocks which can be useful during the examination of a compromised Oracle box. Indeed, this is the subject of the paper "Oracle Forensics Part 7: Using the Oracle System Change Number in Forensic Examinations". Both the tool (which compiles on Linux, Mac OS X and Windows) and the paper are available from http://www.databasesecurity.com/.
