Detecting Steganography in Images

Hi all

Do you know of any packages (or any other method) which enables Zeek to inspect images for steganography (hidden messages)?

For example, imagine some malware was using LSB steganography to exfiltrate data from our network inside innocent looking images. Is there a way for Zeek to flag these images as potentially containing hidden data?

Thanks for your time.

Cheers

Steve
