The given zip file is corrupted.
On opening the file in a hex editor, we can find the corrupted header.
Correct the file header from 70 4B 05 06 to 50 4B 03 04
Then, on unzipping we get a qr code.
Scanning the qr code will give a b64 encoded text: aW5jdGZqe3k0eXlfaEVyRSdzX3kwdXJfZkxhR30=
Decoding it will give the flag.
