Introducing Ducky Software's new file type .dck

Hi everyone, let’s get started.

This is more than likely something we didn’t have to make, but in the interest of transparency—and for anyone who enjoys diving deeper into how we build software—we wanted to share a quick technical update.

Soon, we’ll be introducing a new proprietary file type that will be bundled with certain builds of our software. These files will carry the .dck extension (short for Duck Files) and will ship with various versions of our applications.

Normally, end users will never interact with these files. They’re only visible if someone actively tries to decompile or inspect the code of our products. For example, you may see filenames like:

• iOSb10v1.dck

• Androidb2v1.dck

• content.dck

All of these files are intentionally created and bundled by Ducky Software.

What Happens If You Open One?

If opened in a text editor, a .dck file will look like gibberish—randomized Unicode characters, such as:

╚─├└ 1 – ╗╰╔└╠╣┤┬╚ & ─╦╦╠┬│╩╦┬╗╔ ╚╠╗╚└╠╦y ╗┘ ┐╩┌┼y ╣╗┘╦╰─╠└ ├╠╗╩╚

This is expected. Please do not attempt to modify these files. Each .dck file is referenced by the application in order to ensure attribution and integrity, and their contents can vary between builds.

Why .dck Files?

• Attribution & Integrity: These files help us verify that our products are being used in their intended form.

• Proprietary Encoding: Ducky Software is the only company with the codex to properly encode and decode .dck files.

• Security & Detection: We use multiple detection methods to validate these files at runtime. Any tampering will prevent them from being accepted by our software.

We hope you enjoyed this short technical deep-dive into a behind-the-scenes detail that usually stays invisible.

Thanks for reading,
