Two Truths and a Steg
- Author: Sagnik
This is a steganography challenge involving two seemingly identical images.
We are given:
1
2
before.png
after.png
Although the images look identical, their SHA-256 hashes are different, indicating that the underlying files have been modified.
We can compare the images directly using ImageMagick:
```text id=”4t7h7w” magick compare before.png after.png -compose src diff.png
1
2
3
4
5
6
7
This generates `diff.png`, which highlights the differences between the two images.
Opening the difference image reveals the hidden message:
```text id="4k7g4c"
CYS{th3_d1ff_w4s_th3_p01nt}
Flag
CYS{th3_d1ff_w4s_th3_p01nt}
