[Problem solving]

1. I accessed the server with rcity6 user.

 

 

2. I listed the files, and there was a "flag" file. The problem information said that I shoud find out what type of this file is. So I used file command to find out what it is. "flag" file was a ELF type file. ELF files are executable files that run on Linux, such EXE files.

 

 

3. I tried to check the content of "flag" file using cat command, but the text came out broken.

 

 

4. Then I used strings command to print out all strings to the terminal. As a result, I could find the strings similar with flag pattern/lengths.
