Hi everyone,

I'm not a member of dCTF 2011 Team Reboot, but I dare to start a topic in this forum section. And I give it a title that matches the ones started by Holmes.Sherlock.

What is hidden inside the attached picture? I have to admit that I didn't find it out myself when I ran across it.

 Challenge #4 GC1CYGP.jpg   92.82KB   6 downloads
 Challenge #4 GC1CYGP.zip   92.95KB   14 downloads

Many Greetings

EDIT
I just read the last replies to Challenge #2. So I guess the title #3 is not correct. Sorry about it. I changed it to #4.

EDIT2
I added the file also as a zip archive

Looks like the .JPG has two items included.

One is recognized by graphic programs and shows the picture.

The other one is recognized by e.g. 7zip, and detects an compressed second picture:
 Teil 2.bmp   2.35MB   8 downloads

Hi Peter,

you solved it.
When the file is renamed to .zip it can be opened with any uncompress utility capable of reading zips. Examining this file with a hex editor I didn't notice the zip part.

Many Greetings

Maybe because it is actually Rar compressed ....

Check at offset 0x85DD .
