Stego Hunt

Solution Steps

1. Download the image from the challenge page.
2. Begin your analysis using steganography tools:
   • First, try examining the image metadata using exiftool to check for any hidden information in the image's metadata fields.
   • If metadata analysis doesn't reveal the flag, use zsteg to check for hidden data in the image's least significant bits.
   • As another approach, try steghide to check if any data is embedded using this tool.
3. When examining the metadata, pay special attention to:
   • Comment fields
   • User-defined fields
   • Any unusual or unexpected metadata entries
4. If using zsteg, try different extraction methods:
   • Check all bit planes
   • Look for hidden text in different color channels
   • Examine the output for any patterns that might indicate a flag
5. Once you find the flag, verify that it matches the expected format (UUID).
6. Submit the flag on the challenge page to complete the challenge.

Key Points

• The flag is hidden in a way that requires proper tool usage to extract
• Multiple tools might be needed to find the solution
• Pay attention to all output from the tools, as the flag might be in an unexpected location
