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

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. File: Rescuing_You_in_the_Infinite_Loop.rar ...

: To prevent disk overflow, the script deleted the previous layer after successful extraction. Phase 3: The Final Layer This write-up covers the challenges and solutions for

: The text file contained Base64 encoded strings. Decoding : Extracted the string from flag.txt . Ran a Base64 decode sequence. The resulting plain text revealed the flag. Conclusion Phase 1: Initial Analysis : RAR Archive

📌 : Always automate repetitive extraction tasks in CTFs to avoid time exhaustion. Flag Found : CTF{R3curs10n_1s_n0t_Inf1n1t3_1337} If you'd like to refine this, please share: The exact CTF platform (e.g., PicoCTF, HackTheBox).

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

To bypass the "infinite loop," a Python script was developed using the zipfile and patoolib libraries to automate the process.
