Based on standard Capture The Flag (CTF) methodologies for these types of archive challenges, here is a long-form write-up on how to solve it. File Name : 11-20.7z Category : Forensics / Misc
While there isn't a single famous global CTF challenge exclusively named , this file naming convention is a hallmark of forensics and steganography challenges where players must navigate deeply nested archives or "Russian Doll" files. 11-20.7z
import subprocess import os filename = "11-20.7z" while True: # Attempt to extract. -p can be used if there's a known password. result = subprocess.run(["7z", "x", filename, "-y"], capture_output=True) # Logic to find the next .7z file in the directory next_files = [f for f in os.listdir('.') if f.endswith('.7z') and f != filename] if not next_files: break filename = next_files[0] print(f"Extracted: filename") Use code with caution.
