I have worked in the Cybersecurity industry for some time, and often I find myself asking "What would this file look like in my logs if I downloaded/emailed/executed it?"

This Repo of file types that I intend to add to should address that, giving me useful information such as:

1. An example file (so often difficult to find)
2. Mime Types where applicable
3. Header Signatures (Magic Bytes) where applicable
4. Security Concerns and examples

For the example files, I will try and create these myself, typically they will contain a minimal amount of data, such as "test".

For file requests, please open an Issue and I'll see what I can do!

A useful resource I've found with tonnes of other file types and more detail that might cover what's missing:
