Try with many tool, and have:

$ zsteg aee487a2-49cd-4f1f-ada6-b2d398342d99.SteinsGate
/usr/lib/ruby/2.3.0/open3.rb:199: warning: Insecure world writable dir /mnt/c/ProgramData/Oracle/Java in PATH, mode 040777
imagedata           .. text: " !#865   "
b1,r,msb,xy         .. text: "y5b@2~2t"
b1,rgb,lsb,xy       .. file: Keepass password database 2.x KDBX
b2,r,msb,xy         .. text: "\rP`I$X7D"
b2,bgr,lsb,xy       .. text: "b;d'8H~M"
b4,g,msb,xy         .. text: ";pTr73& dvG:"

After, get file KDBX with zsteg:
$ zsteg aee487a2-49cd-4f1f-ada6-b2d398342d99.SteinsGate -E b1,rgb,lsb,xy > test.kdbx

But file test.kdbz can't open because i don't have password.
A long time after, i try brute force with rockyou.txt but not good?
Are you kidding me?

With hint:

    pix and password
    weak password!
    lower casee letters and number
    len(password) == 10
    hitb + number
Use John the Ripper, i get password: hitb180408

Wow, get flag so easy: HITB{p1x_aNd_k33pass}
