# A Musical Mix-up:Steg / Forensics:200pts
One of our guys found a strange midi file lying around on our servers. We think there might be some hidden data in it. See if you can help us out!
[challenge.mid](challenge.mid)
# Solution
challenge.midを開いてみても、ピアノ曲が流れるだけである。
stringsしてみる。
```bash
$ strings -n 1 challenge.mid | tr -d "\n"
