We get a .png file. I found nothing interesting in file, strings, grep and zsteg. Only interesting maybe was this part of exiftool output:

I decided to left it for later. I decided to check Bit Planes and it showed something. When I checked Planes 0 I saw many strange texts, but only on alpha plane 0 there was strange text on the middle: Q0lUezRWdTF1MXpofQ==. It looked like base64 crypted text, so I decrypted it and got the flag.
