Hacker101 Encrypted Pastebin Patched

The Hacker101 CTF Encrypted Pastebin is a notoriously difficult, high-level challenge requiring automated exploitation of a padding oracle vulnerability in AES-CBC encryption, rather than simple input manipulation. The exercise demands significant knowledge of cryptographic padding and bit-flipping attacks, often utilizing tools like PadBuster to forge data and extract multiple flags. A detailed walkthrough of this, along with others, can be found in the user-maintained documentation CTF — Hacker101 — Encrypted Pastebin | by Ravid Mazon
