: The encryption mode used here, where each block of plaintext is XORed with the previous ciphertext block before being encrypted. Step-by-Step Guide 1. Identify the Vulnerability

Welcome back to the CTF series! Today, we’re tackling one of the most notorious "Hard" challenges in the Hacker101 CTF Encrypted Pastebin hacker101 encrypted pastebin

The application typically uses . In CBC mode, each block of ciphertext is XORed with the next block's plaintext during decryption. This structure allows an attacker to manipulate one block to "guess" the plaintext of the next block byte-by-byte. 3. Automate the Attack : The encryption mode used here, where each
