Invisible Ink [388 Points]

"The flag is hidden somewhere in this GIF. Can’t see it? It must be written in transparent ink."

Author: Yes

Solution

Similar to the previous challenge, open the GIF file using GIMP and analyze it.

In this case, I noticed two frames appeared transparent, and neither of them was located at the default (0, 0) coordinates for X and Y. To investigate further:

1. Move these transparent frames to the (0, 0) position.

2. Make only these two frames visible.

After making this adjustment, the frames resembled a static noise pattern, similar to a TV signal. By equalizing the colors, the output revealed a white screen.

Upon closer inspection, equalizing just one frame initially showed faint text. To make the text more readable, I adjusted the transparency settings.

This revealed the flag hidden within the GIF.
