Files Metadata

Theory

To identify potential target users and gather information about their operating systems and installed application software, we might review the metadata of publicly accessible documents linked to the target organization.

Practice

We may find and download target organization's publicly accessible documents by using google dorks such as site:example.com filetype:pdf or by directly downloading files from the organization's website.

Then, exfitool can be used to inspect metadata tags

# -u : Display unknown tags
# -a : Display duplicated tags
exiftool -u -a corpo-image.png
