- SMTP protocol headers now do some minimal parsing to clean up
email addresses.
- New function named split_mime_email_addresses to take MIME headers
and get addresses split apart but including the display name.
- Update tests.
We now extract email addresses in the fields that one would expect
to contain addresses. This makes further downstream processing of
these fields easier like log analysis or using these fields in the
Intel framework. The primary downside is that any other content
in these fields is no longer available such as full name and any
group information. I believe the simplification of the content in
these fields is worth the change.
Added "cc" to the script that feeds information from SMTP into the
Intel framework.
A new script for email handling utility functions has been created
as a side effect of these changes.
These functions are now deprecated in favor of alternative versions that
return a vector of strings rather than a table of strings.
Deprecated functions:
- split: use split_string instead.
- split1: use split_string1 instead.
- split_all: use split_string_all instead.
- split_n: use split_string_n instead.
- cat_string_array: see join_string_vec instead.
- cat_string_array_n: see join_string_vec instead.
- join_string_array: see join_string_vec instead.
- sort_string_array: use sort instead instead.
- find_ip_addresses: use extract_ip_addresses instead.
Changed functions:
- has_valid_octets: uses a string_vec parameter instead of string_array.
Addresses BIT-924, BIT-757.
- policy/frameworks/intel/seen is the new location for the scripts
that push data into the intel framework for checking.
- The new policy/frameworks/intel/do_notice script adds an example
mechanism for data driven notices.
