How to Detect JavaScript in a PDF

Question

Is there any way to determine if a PDF contains JavaScript?

This may sound weird, but I want to conclusively prove or disprove this case and I'm wondering if there are any methods beyond what I've tried.

This is what I've tried:

- Looked for any controls on the document. There are none.

- Checked the document actions. None of them contain any code.

- Opened the file in NotePad++. I did not notice anything that would differentiate between a file with JavaScript or without.

- Examined the file using itext-rups-5.5.9. This tool confirmed the file didn't have any fields or controls, but I couldn't figure out where it would tell me about document level stuff.

Anyone have any other ideas? Many thanks.

I have had a pdf or two that was blocked by my antivirus for having a script, can you explain what this mean exactly and what the implications are?

To check if file has any scripts, you can go to 'Prepare form' tool and click on 'More' and 'All JavaScripts'.
