Report written to panhunt_YYYY-MM-DD-HHMMSS.txt
The script uses regular expressions to look for Visa, MasterCard or AMEX credit card numbers in document files. Zip files are recursed to look for document files. PST and MSG files are parsed and emails and attachments searched in. The script will list but does not yet search Access databases.
