zinky

Use the zip details of post 2007 office documents to find hinky files.

Installing

1. Download and install python2.7 https://www.python.org/download

2. Download and install docopt https://github.com/docopt/docopt

Example Output

Below is an example output from zinky. It shows a few indications that the document may have been faked:

1. The [Content_Types].xml file is normally found as the first entry in a zip created by Microsoft products. When documents have been modified and zipped with other software this isn't always the case, and therefore may be hinky.

2. The embedded dates within docProps/core.xml don't match the zip date for the file. The document properties seem to show that the document was modified in 2000 but the zip date is 2014-09-16T13:24:24. This should be either 1980-01-01T00:00:00 or the actual date the file was written. The fact it is different again suggests that the file is hinky.

3. The folders within the zip have dates later then the document properties. These should be 1980-01-01T00:00:00 or the actual date the file was written. The fact they aren’t suggests the zip has been written to disk and re-zipped after some modifications.

4. The internal_attr and external_attr for the contents are none-zero. Files written by Microsoft products typically set these values to 0.

5. The flag_bits are not equal to 6, which is normally expected when files are written Microsoft products.

6. The create_version and the extract_version are all identical. Typically when a file is written by Microsoft products the create_version for folders and xml files is 45 and the extract_version is 20. For embedded jpeg files this would normally be a create_version of 45 and an extract_version of 10.

7. The compress_type is the same for all files. Normally when files are written by Microsoft products the compress_type will vary depending on the content that is being compressed. For example xml files are typically compress_type 8 and thumbnail jpeg files are compress_type 0
