Points: 200

Binary Exploitation

Question

To be successful on your mission, you must be able read data represented in different ways, such as hexadecimal or binary. Can you get the flag from this program to prove you are ready? Connect with nc 2018shell.picoctf.com 14390.

Hint

  • I hear python is a good means (among many) to convert things.
  • It might help to have multiple windows open

Solution

Basically what here happened, after we connect we this post and host they provide data that has been converted to binary, hex, octal and challenge is we need to convert it into ASCII within 30 seconds. so we wrote a python script for time consuming

Hope you enjoy. Subs me share this post. Keep in touch for more amazing challenges.
