'December of 3540. Zumzum Planet. The Bureau of Space Surveying.

Unit 1337 Agents,

Our transgalactic Striker craft 0xDEADBEEF has captured a suspicious message coming from the direction of the "colorful planet". Our bureau of cryptography has managed to decode the transmission. Unfortunately the image is undecipherable and contains suspicious artifacts.

We're suspicious that there's a real message buried deeper inside. We're asking you to help. Your task is to find the real message.

Our hopes are in you!

Good luck!' -- this time write-up made by a special guest!

Unit 1337 Agents,

During operation "Dalmatian", corvette "Storm", operating on the border of territorial seas, captured mysterious message along the weather report. Sadly, our Cipher Bureau "XOR" is under renovation and our cryptologists are left without their workplaces.

Investigate the signal.

Good luck!

'Lately, our agents managed to capture a PNG file. Supposedly, there's a hidden message in it, somewhere, but we didn't manage to retrieve it just yet.

Maybe you'll have more luck.

Good luck!' - or the write-up that arrived... two months late?

'While searching through captured drives, we've found an encrypted ZIP file. Since we don't know the password - and have reasons to suspect it's strong, thus not guessable nor breakable - we're turning to you, requesting your help.

Good luck!' - or read enough of what ZIP is to solve it.

'Operation codename: Pasokon
During the operational game our spy (codename Martin) managed to intercept hostile communication.

Unfortunately, we have no idea how to decode it. To make matters worse, our most well versed in crypto agent (codename Scottie) is on a mission right now and cannot help us. Your handler advised to use your skills. The fate of the Chunar rests in your hands!
And remember - if something is not clear, you have a license to bruteforce.

Good luck!
Over and out.' - This mission. What a ride.
