Hi! Sometimes, enterprises use VPN to let employees connect to the local
network from their homes. So it is logical to try to break into the local
network using their credentials.

Also, VPNs are used as a way to gain certain degree of anonimity. So your
connection cannot be easyly tracked back to you, if there's some sysadmin
vigilant.

Hope this helps.
