Mission 0x03

🔎 Solution​

After SSH'ing in as angela, the next task was to retrieve emma's password, which the mission states is located on line 4069 of a provided file:

angela@venus:~$ cat mission.txt 
################
# MISSION 0x03 #
################

## EN ##
The password of the user emma is in line 4069 of the file findme.txt

There are multiple ways to extract a specific line from a file. I used a simple head + tail pipeline to get line 4069:

angela@venus:~$ head -n 4069 findme.txt | tail -n 1
fIvltaGaq0OUH8O

Explanation:

  • head -n 4069 findme.txt prints the first 4,069 lines of the file.
  • The pipe | passes that output as input to the next command.
  • tail -n 1 takes the last line from the piped input, which is line 4,069 of the original file.

With the recovered password I SSH'd into emma:

ssh emma@venus.hackmyvm.eu -p 5000

Inside emma's account I read the flag file:

emma@venus:~$ cat flagz.txt 
8===0daqdDlmd9XogkiHu4yq===D~~
