[Capture The Flag] Old Memories

Draco · April 25, 2018, 4:06am

Capture The Flag challenges are hacking puzzles.
You must find a text string flag somewhere and PM it to me and I will tell you if it is correct or not…
Normally it is in the form “CTF{something}” but not always. Good Luck!
This challenge closes on 5/2/2018. After this date, we will discuss it.

Old memories
BY ABHIAR

General RONX was cleaning up his cupboard last night, when he finds this archive out of the blue. He recalls that it was something about what he loves immensely. But the old General does not remember what it was. He sent this to me but I don’t know what to do with it. Can you find it out?

Alright, since most people are having problems with this one. I will give a major hint in a few hours.

Hint: Do the two images relate in any way?

This one was difficult for many people.

The Flag is “CTF{I_LOV3_PYTHON}”

If you look inside the zip file there are two images.

Image 1

Image 2

How in the world do you get a flag from this static?
Well, believe it or not, you can solve it with an online tool or any number of tools like Photoshop.
It is just the difference (or what is the same) between the two images.
