Hello,

It's been sometime since I've used GAM but wanted to know if it's possible to search from a specific users inbox against a stand-alone regex policy for Credit Card Number(s)? 

Trying to generate a report utilize a tool like Cloudlock, but at the same time wanted to see if I could use GAM for a second opinion.

Any insight or best practice would be great :)

Thanks in advance!

Carlos,

Here is the Gmail query documentation: https://support.google.com/mail/answer/7190

I don't see anything about regex searching.

Hey Ross,

I did some research on "User Gmail Messages Thread" and found that I can meet the PCI Assessment requirements by look into attachments in which, the following was useful :

showattachments [attachmentnamepattern <RegularExpression>] - Display message attachemnts (MIME type text/plain); you can limit the attachments shown with attachmentnamepattern <RegularExpression>

Additionally for anyone interested in conducting regex match on a user/group message thread, you can simply pull down the entire email block and run it against a simple | grep regex match.

# Utilize GAM to show messages including the email body, as this is what I need to run the regex match. Dump output into file.
gam <UserTypeEntity> show messages showbody convertcrnl > audit_file.txt

# Simple grep regex match did the trick to help isolate pattern match. In this case I utilized a regex known to identify VISA|Mastercard card numbers.
echo audit_file.txt| grep -Eo "REGEX_TYPE"

Hope this helps someone down the line!

Carlos
