Bandit Level 11 → Level 12

Introduction

In Level 11 of the Bandit wargame, we're faced with a cryptographic challenge that requires some clever manipulation. Let's jump right into the steps to crack it.

Steps.

Access the Remote Server: Open your terminal and connect to the remote server using this command:

ssh bandit10@bandit.labs.overthewire.org -p 2220

Input the password from the previous level: 6zPeziLdR2RKNdNYFNb6nVCKzphlXHBM.

Decrypt with tr: Once connected, run this command to decrypt the data:

cat data.txt | tr 'A-Za-z' 'N-ZA-Mn-za-m'

The tr command shifts each letter by 13 positions, revealing the concealed message.

The output of the command contains the password for the next level:
