Who are you? What do you folks even do?

At Innofactor, we innovate to make the world work better together with over 500 Nordic colleagues. Our objective is to help our customers digitalize their business, promote a collaborative way of working, and develop business processes using secure cloud services. In November 2021, our brand new office in Jyväskylä was opened, and we now have seven offices in Finland in total.

I heard something about DigiStar, spill me the beans!

The Innofactor DigiStar program offers an excellent opportunity to become a hard-core expert in modern technology. The application period of our DigiStar program is now open!

The Challenge

Oh noes! NoobHansa is a thriving Finnish company manufacturing the Premium PuuHöylä Products™ of the finest quality, which have served PuuHöylä aficionados for decades. However, it seems like they've made some very basic mistakes in securing their IT environment.

Your mission, should you choose to accept it, is to find a way to collect all of the flag keys planted inside the NoobHansa environment. The keys are 16-character alphanumeric strings, unless stated otherwise.

The challenges are separate; you don't need to finish them in chronological order. They are all quite easy, actually.

The Prize

So, what will I get for this? Instead of fancy NFTs, we will be giving out actual prizes.

First place

JBL Flip 5 Bluetooth Speaker

Innofactor Swag Kit (Backpack, thermos flask and a reflector)

Second & Third place

2000 mAh Quick Charge-compatible PowerBank

Innofactor Swag Kit (Thermos flask and a reflector)
