Possibility to extract and match on file meta-data

[forgedhallpass]

The file protocol could be extended to retrieve additional meta-data of the target files. The data could be made available on the template context, so that matchers and extractors could be applied over them.

Such metadata could be:

• EXIF data of images (could be used for OSINT)
• password protection, certificates, general description containing (sub)domains, e-mail addresses of PDF and other binary document files
• calculated hash of the file. It could be used to identify file dependencies (e.g. JARs) that contain known vulnerabilities
• etc.

In order to decide on implementing such functionalities, we need describe potential use-cases.
