Description
Our flag printing service has started glitching!$ nc saturn.picoctf.net 49700
Hint
Step 1
When you netcat to the server you get the following
g2_pilot_tester-picoctf@webshell:~$ nc saturn.picoctf.net 49700
'picoCTF{gl17ch_m3_n07_' + chr(0x61) + chr(0x34) + chr(0x33) + chr(0x39) + chr(0x32) + chr(0x64) + chr(0x32) + chr(0x65) + '}'
^C From this we can just use the Python interpreter to give us the correct char values
g2_pilot_tester-picoctf@webshell:~$ python
