Panda

The main idea finding the flag is using zip2john.

Step-1:

After I downloaded panda.zip, I got 2 files in it, panda.jpg & panda1.jpg.

Step-2:

It was encrypted. So I used zip2john tool to crack the zip.

zip2john panda.zip > hash.txt
john.exe --wordlist=real_human hash.txt

Step-3:

This simple flag.py python script helps us to get the flag.

print(''.join([chr(i) for i, j in zip(open('panda1.jpg', 'rb').read(), open('panda.jpg', 'rb').read()) if i!= j]))

Step-4:

Finally the flag becomes: csictf{kung_fu_p4nd4}
