Sweet little challenge
Took me a while to notice that the file is too big for such a "small" image.
The rest was easy

This was what tipped me off:
1 [samc ~/hacker/fuzzy_dust]$ identify fuzz.bmp
fuzz.bmp[0] BMP 420x300 420x300+0+0 8-bit DirectClass 738kb
fuzz.bmp[1] BMP 420x300 420x300+0+0 8-bit DirectClass 738kb

[boom@gate bin]$ ./zsteg ../../../fuzz.bmp
[?] 378054 bytes of extra data after image end (IEND), offset = 0x5c4c6
extradata:0 .. file: PC bitmap, Windows 3.x format, 420 x 300 x 24
[boom@gate bin]$ ./zsteg -E "extradata:0" ../../../fuzz.bmp > ../../../output.bmp
[boom@gate bin]$
zsteg did a very good job. I did the comparison with gimp, using two layers and layer mode "difference".
