For this level, a plaintext password is not used; instead, an RSA private key obtained from the previous level is required. Connection Command:
ssh -i bandit17.key bandit17@bandit.labs.overthewire.org -p 2220Concept
File Diffing. Identifying changes between versions of the same dataset. This is fundamental for forensic analysis or configuration auditing.
Key Commands
diff [file1] [file2]: Compares files line by line.cat: To verify the content before comparing.sort: Useful if the files are not in the same order (though they usually are in this level).
Walkthrough
Upon entering the server with the RSA key, I found two files: passwords.old and passwords.new. I used diff to identify which line had changed. The command pointed out that line 42 had been modified. The string marked with > is the new password.
Key Takeaways
I learned to read the diff syntax: the < symbol represents the source file and > represents the destination file. This tool is vital to avoid searching manually through thousands of lines of similar text.
