Question

During your adventure, you will likely encounter a situation where you need to process data that you receive over the network rather than through a file. Can you find a way to save the output from this program and search for the flag? Connect with 2018shell1.picoctf.com 48696.

Hint

Remember the flag format is picoCTF{XXXX}

Ever heard of a pipe? No not that kind of pipe... This kind

Solution

The pipe or the | passes standard output into standard input.

Connect to the service and pipe output to grep

Do nc 2018shell1.picoctf.com 48696 | grep pico to get flag.

Flag

picoCTF{almost_like_mario_f617d1d7}
