CTF prepare challenge

Fortytwo Security hosts on the 25th of September a Capture The Flag (CTF) Event for students. To prepare the student for this event FortyTwo made a challenge for everybody to try out!

Challenge: Find the flag inside the image

This Challenge is an image file with a flag hidden somewhere inside. Can you find the flag?

Pssst…. the flag looks like MARVIN{S0meN0n3Gu3ssableT3xt}.
Start by downloading the image 😉

If you need another hint you can download the write-up here.
