Libclamav includes a DLP module which can detect the following
credit card issuers: AMEX, VISA, MasterCard, Discover, Diner's Club,
and JCB and U.S. social security numbers inside text files.
Future versions of Libclamav may include additional features to
detect other credit cards and other forms of PII (Personally
Identifiable Information) which may be transmitted without the
benefit of being encrypted.
