Recon

Opening the white.png image reveals what appears to be a completely white image, just as the challenge suggests. However, this does not necessarily mean that all the pixels are identical: there may be subtle differences that are invisible to the human eye.

Flag capture

By extracting all bitplanes from the image, we can reveal the flag hidden within one of them. Tools like StegOnline make this process straightforward and user-friendly.
