We were given the challenge text:
hello guys, I started this new service check note.txt file for a sanity check 207.180.200.166 2324
Along with the file reader.py.
This was quite an easy challenge, and I got it on the first try which was a nice confidence boost for harder challenges. Since /flag.txt as banned, I tried /f* instead, which worked. The flag was flag{oof_1t_g0t_expanded_93929}.
