File Analysis Framework related code has been moved into a separate
script. Using redefinitions of the corresponding records causes the
file-related columns to appear last.
This patch allows users to provide the fuid or the connection id
directly, in case they do not have access to either in the event that
they handle.
An example for this is the handling of certificates in SSL, where the
fa_file record cannot be retained because this would create a cyclic
data structure.
This patch also provides file IDs for hostname matches in certificates,
which was not possible with the previous API.
The intel-framework now supports the new indicator type Intel::SUBNET.
As subnets are matched against seen addresses, the field matched was
introduced to indicate which indicator types caused the hit. A testcase
for subents was added and the old ones have been updated accordingly.
- Plain text now identified with BOMs for UTF8,16,32
(even though 16 and 32 wouldn't get identified as plain text, oh-well)
- X.509 certificates are now populating files.log with
the mime type application/pkix-cert.
- File signatures are split apart into file types
to help group and organize signatures a bit better.
- Normalized some FILE_ANALYSIS debug messages.
- Improved Javascript detection.
- Improved HTML detection.
- Removed a bunch of bad signatures.
- Merged a bunch of signatures that ultimately detected
the same mime type.
- Added detection for MS LNK files.
- Added detection for cross-domain-policy XML files.
- Added detection for SOAP envelopes.
