Modify an existing configuration template under the /sniper/conf/ directory (ie. /usr/share/sniper/conf/vulnscan_only) and add your Nessus IP, username and password to the appropriate fields seen below.

NOTE: You can also create a copy of an existing template you want to use and modify that template to configure your scan as well (see here for details on creating dynamic configuration templates):

NESSUS_POLICY_ID="c3cbcd46-329f-a9ed-1077-554f8c2af33d0d44f09d736969bf" #DEFAULT POLICY

Selecting A Scan Policy

To select a different scan policy to use for the scan, you will need to use web developer tools while accessing the Nessus web UI. To do this, click the “Policies” menu and click on the policy you want to use for Sn1per scans and click “Save”. Under the “Network” tab in web developer tools, you will see a “PUT” request with the UUID of the policy on the request body. You will need to update your Sn1per conf NESSUS_POLICY_ID setting with this value prior to running the scan.

Running scans

Run a test vuln scan to confirm your installation:

sniper -t <target> -c <full_path_to_your_sn1per_custom_conf> -m normal -w <workspace_name>

NOTE: This can also be done using the Command Execution Add-on from the web UI.


After the scan(s) complete, results will be shown in the workspace report view under the “Vulnerabilities” section and from the host report as well as the “Vulnerability Report Viewer“.
