Mission 0x17

🔎 Solution

After logging in as eva, the next hint pointed toward a file that hadn't been modified in decades - specifically May 1, 1968.

The password of the clara user is found in a file modified on May 1, 1968.

To locate files based on modification date, the find command provides a useful option: -mtime.

Quick breakdown of its behavior:

• -mtime N → files modified roughly N days ago (between N and N+1).
• -mtime +N → modified more than N days ago.
• -mtime -N → modified within the last N days.

Since 1968 is extremely far back - roughly 20000 days - files modified that long ago should fall under -mtime +20000. Running the search:

eva@venus:~$ find / -mtime +20000 2>/dev/null
/usr/lib/cmdo

Only one result appeared. Checking it confirmed it contained what looked like a password:

eva@venus:~$ cat /usr/lib/cmdo 
39YziWp5gSvgQN9

Using that as a credential allowed an SSH login as clara:

ssh clara@venus.hackmyvm.eu -p 5000

Once inside, the flag was waiting:

clara@venus:~$ cat flagz.txt
