Abstract
Mac OS X-based systems are gaining growing popularity. Yet forensics on this type of systems is still in its infancy and traditional forensic tools do not work well with it. Currently, most examinations for Mac OS X systems are done manually by experts. It is costly and time consuming, especially for those examination tasks involved with large amount of data, such as forensic examination of log files. It is critical to develop new techniques and tools for facilitating Mac OS X-based forensic examination. To address this issue, we have first proposed and developed an automatic log file analyser, which can automatically carve forensic artefacts from multiple log files for facilitating forensic analysis on Mac OS X systems. The experimental evaluation shows our tool can handle large size of data effectively, which enables investigators to analyse log files in a time manner.
