Challenge: Cracking the Password

It is late at night and it has been a very tough day. You discovered early in the morning that one of your main critical systems was compromised. You found that someone accessed it with a privileged user, using a service or application that requires authentication. You wondered if there was a new 0-day vulnerability, or if someone got the password for this user? It seems the logs gave you the response, because they registered the IP address (an internal machine) from where the connection to the critical system was established. You had time to investigate that internal box, and found a file called "password" containing the following string:

VOhRrmhZvX7lEG9KvuF/6FVA

Questions:

1. What is the system or application that use this kind of password string and for what purpose?
2. What is the format and crypto algorithm(s) used on this password string?
   
3. What is the clear-text password of your critical system? Please, detail the process you followed and the tools you used to obtain the password.
