In this script, we'll harvest information about the PST file, taking note of the messages in each folder and generating statistics for word usage, frequent senders, and a heat map for all email activity. Using these metrics, we can go beyond the initial collection and reporting of messages and explore trends in the language used or communication patterns with certain individuals. The statistics section highlights examples of how we can utilize the raw data and build informative graphics to assist the examiner. We recommend tailoring the logic to your specific investigation to provide the most informative report possible. For example, for the word count, we'll only be looking at the top ten words that're alphanumeric and longer than four characters, to help reduce common words and symbols. This might not provide the correct information for your investigation and might require tailoring to your specific situation.
