Search for AMEX Credit Card Numbers
Following is a simple
.audit file that looks for a list of file types that contain a properly formatted AMEX credit card number.
file_extension: 'pdf', 'doc', 'xls', 'xlsx', 'xlsm', 'xlsb', 'xml', 'xltx', 'xltm', 'docx', 'docm', 'dotx', 'dot', 'txt'
expect: 'American Express', 'CCAX', 'amex', 'credit', 'AMEX', 'CCN'
The output we get this time is as follows:
No files were found to be in violation.
We were able to “pass” the audit because none of the files we audited contained an AMEX credit card number.
