Description

I wonder what type of file the flag is....

Deduction Time

We are given a text file the-flag.txt, or so it seems...

Let's try printing it out

Indoubetably, we can check with file the-flag.txt

the-flag.txt: PNG image data, 1536 x 864, 8-bit/color RGB, non-interlaced

Rename the file with the proper extension using mv the-flag.txt the-flag.png

Flag

retroCTF{TH4t_w45_P34nU75}

Our keen eye of observation will notice the "PNG" printed at the top, so perhaps this is not a txt file after all
