The objective was to extract a hidden flag from a recursively compressed archive. The file presented a "Zip Bomb" style structure where each extracted layer contained another password-protected or obfuscated archive, requiring automated extraction to reach the final payload. Phase 1: Initial Analysis : RAR Archive.

: To prevent disk overflow, the script deleted the previous layer after successful extraction. Phase 3: The Final Layer

: Some layers utilized simple password protection or varying compression formats (ZIP, RAR, 7z). Phase 2: Automation Scripting

Any or tools you used (e.g., John the Ripper, Python). The actual flag you discovered.

This write-up covers the challenges and solutions for the capture-the-flag (CTF) task involving the file . Challenge Overview

: The sheer number of layers (100+) made manual extraction impossible.

: Manual extraction revealed a nested file structure (e.g., layer100.zip -> layer99.zip ).
