-- text --
We, the Boro Cyber Division have been spying on the chats of a group of local hackers.
We used to be able to decrypt their chats from base64 but they seemed to have changed their encoding.
Can you find out what they’re talking about now?

--[ Recon / Initial Analysis ]--
This archive-style writeup preserves the official prompt and materials from
BoroCTF challenge 045. The numbered source file did not include expanded solve
notes for approach, findings, or flag, so this page keeps the verified challenge
material without adding unverified exploit steps.
Use the prompt, connection details, and any listed files above as the starting
point for a replay or future expanded solve.
────────────────────────────────────────────────────────────────────────────────
--[ Exploitation / Solution ]--
No solve transcript was present in the numbered source file. If a verified solve
is added later, this section should be replaced with the actual commands,
payloads, scripts, and final flag path.

--[ Key Takeaways ]--
- The challenge prompt and provided materials are preserved in the site's
BoroCTF archive.
- The page avoids inventing solve details where the source entry only contained
scaffolded note fields.
- Author metadata is normalized to Imattas aka Zemi.
