 Let's Start! The Challenge Prompts us to connect to the target .Then it gives us 3 choices to make(**2nd**) is real deal here.
![msg1](msg1.png)   Then it asks us to find the flag and gives us the Y/N option,
![msg2](msg2.png)
Although both the options are same :laughing: Then comes the interesting part, We start by issuing the command _echo ls_ . This gives a list of some DOS installation files. A lot of time was wasted in this step , first for guessing the right command and then to check all the files one by one with that command.The commmand was _file FILENAME_ and the file was _GRAPHICS.COM_ . Next step was to check for good looking strings in that file by _strings FILENAME_ command and BTOOOM!! 
# The FLAG was there.## TUCTF{4LW4Y5_1NF3C7_7H353_19742_BY735}
