SSH Auditor is the best way to scan for weak ssh passwords on your network. SSH Auditor will automatically:

  • Re-check all known hosts as new credentials are added. It will only check the new credentials.
  • Queue a full credential scan on any new host discovered.
  • Queue a full credential scan on any known host whose ssh version or key fingerprint changes.
  • Attempt command execution as well as attempt to tunnel a TCP connection.
  • Re-check each credential using a per credential scan_interval – default 14 days.

It’s designed so that you can run ssh-auditor discover + ssh-auditor scanfrom cron every hour to to perform a constant audit.

Create initial database and discover ssh servers

$ ./ssh-auditor discover -p 22 -p 2222 192.168.1.0/24 10.0.0.1/24

Add credential pairs to check

$ ./ssh-auditor addcredential root root
$ ./ssh-auditor addcredential admin admin
$ ./ssh-auditor addcredential guest guest --scan-interval 1 #check this once per day

Try credentials against discovered hosts in a batch of 20000

$ ./ssh-auditor scan

Output a report on what credentials worked

$ ./ssh-auditor vuln

RE-Check credentials that worked

$ ./ssh-auditor rescan

Output a report on duplicate key usage

$ ./ssh-auditor dupes
