We'll I'm stumped.. Converted to binary and its meaning less.. The repetition on the last few characters makes me think Base64 but I cant see how its offset/encrypted..

Here is the code to save having to type it in:

code:
eb 04 af c2 bf a3 81 ec  00 01 00 00 31 c9 88 0c

0c fe c1 75 f9 31 c0 ba  ef be ad de 02 04 0c 00

d0 c1 ca 08 8a 1c 0c 8a  3c 04 88 1c 04 88 3c 0c

fe c1 75 e8 e9 5c 00 00  00 89 e3 81 c3 04 00 00

00 5c 58 3d 41 41 41 41  75 43 58 3d 42 42 42 42

75 3b 5a 89 d1 89 e6 89  df 29 cf f3 a4 89 de 89

d1 89 df 29 cf 31 c0 31  db 31 d2 fe c0 02 1c 06

8a 14 06 8a 34 1e 88 34  06 88 14 1e 00 f2 30 f6

8a 1c 16 8a 17 30 da 88  17 47 49 75 de 31 db 89

d8 fe c0 cd 80 90 90 e8  9d ff ff ff 41 41 41 41


And here is the binary version (well as good as it can be displayed in a browser).


code:
‚‚‚‚ÿÿÿ¹		³‘ÛŒ{®’âè[èQh8QoO x(`,x,Q`(Q`8@KŒÛŒŒó”û‘‹‘{‘%Ïó”û‘g‘‹‘ZÜ®BBBB¼®‚‚‚‚¼:    ÃÇ‘   :—®ƒ0< 8 <Q08QSƒ 0 @{µ}÷]ŒŸ®ƒ00“Œ  € 7ÅýCõ ×

There is encrypted data in the PNG image header and it's x86 code.

GCHQ is usually piss poor for salaries but then again it's probably a fairly interesting job compared to a lot of other IT jobs.

I've seen the comment in the header:


code:
QkJCQjIAAACR2PFtcCA6q2eaC8SR+8dmD/zNzLQC+td3tFQ4qx8O447TDeuZw5P+0SsbEcYR78jKLw==


It appears to be MIME /BASE64 but its not

Kinda difficult to compare with private sector code cracking jobs though.

Show me where I've said "the answer is here". Obviously the keyword isn't posted in big bold letters on the page ffs Face it, you don't have a clue, just like the rest of us.
