Mission 0x10

🔎 Solution

After connecting via SSH as isla, the next objective was to locate the password stored inside the file passy. According to the hint in mission.txt, the correct line starts with a9HFX, but those first 5 characters are not part of the actual password.

To search for the required string inside the file, I used grep:

isla@venus:~$ cat passy | grep "a9HFX"
WKINVzNQLKLDVAca9HFX
dWeFra9HFXzNQLKLDVAc
kfRgNa9HFXzNQLKLDVAc
zNQa9HFXfEtrgLKLDVAc
WKINVzNQLa9HFXDwErfc
WKINVa9HFXzDcceWeTfd
a9HFXWKINVzNQLKLDVAc

Removing the first 5 characters gives the password:

WKINVzNQLKLDVAc

With the password recovered, I logged in as the user:

ssh violet@venus.hackmyvm.eu -p 5000

Once inside, reading the file revealed the final flag:

violet@venus:~$ cat flagz.txt
8===LzErk0qFPYJj16mNnnYZ===D~~
