You won't get the real flag.txt even after extraction! Probably.
Beginner Hint
- If you read make_zip.py, you can see that many flag.txt entries are created.
- When you extract flag.zip, depending on the tool, you may get two files, such as README.md and flag.txt.
- Even if you look at this flag.txt, it only says
No flag here. Try harder. - This is because the flag.txt containing the flag can be overwritten or ignored due to duplicate entries.
