# Description Can you conjure the right bytes? The program's source code can be downloaded [here](https://challenge-files.picoctf.net/c_candy_mountain/3bbe7f76772ee17090e5fa64685d4eebc59c44c65f8f181eab667aff96e3602a/app.py). Connect to the program with netcat: `$ nc candy-mountain.picoctf.net 63986` # Hints 1. Solving this with a one-liner will help with the next challenge in this series # Solution 下載檔案後,是一個名為 app.py 的檔案 ```python while(True): try: print('⊹──────[ BYTEMANCY-0 ]──────⊹') print("☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐") print() print('Send me ASCII DECIMAL 101, 101, 101, side-by-side, no space.') print() print("☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐") print('⊹─────────────⟡─────────────⊹') user_input = input('==> ') if user_input == "\x65\x65\x65": print(open("./flag.txt", "r").read()) break else: print("That wasn't it. I got: " + str(user_input)) print() print() print() except Exception as e: print(e) break ``` \x65 就是 e 我們需要輸入 3 個 e 就會拿到 flag 所以使用 echo 串 nc 就可以了 `echo eee | nc candy-mountain.picoctf.net 63986`
