• Author: Aditi Sahu

This is a steganography and file forensics challenge. The provided PNG appears to be corrupted, so we inspect the file contents instead of relying only on the image.

Using the strings command, we can search for readable text inside the binary file:

1
strings challenge.png | grep CYS

This reveals the hidden flag appended at the end of the PNG file:
