## Solution
Connecting in SSH will trigger a wonderful 8 bit *Nyan Cat* representation.
The flag is probably hidden in the data flow. To intercept it, the data exchanged with the server must be analyzed.
A [Python script](https://raw.githubusercontent.com/m3ssap0/CTF-Writeups/master/STEM%20CTF%20Cyber%20Challenge%202019/Nyan/nyan.py) can be written to help on this.
```pythonimport refrom pwn import *
l = listen()shell =  ssh(host="138.247.13.114", user="ctf", password="ctf")sh = shell.run('sh')while True:   received = sh.recvline()   if "MCA{" in received:      x = re.findall("MCA\{.+\}", received)      print x[0]      break```
The flag is the following.
```MCA{Airadaepohh8Sha}```
