Getting Started

Installation

To get started with the Python library for Shodan, first make sure that you’ve received your API key. Once that’s done, install the library via the cheeseshop using:

$ easy_install shodan

Or if you already have it installed and want to upgrade to the latest version:

$ easy_install -U shodan

It’s always safe to update your library as backwards-compatibility is preserved. Usually a new version of the library simply means there are new methods/ features available.

Connect to the API

The first thing we need to do in our code is to initialize the API object:

import shodan

SHODAN_API_KEY = "insert your API key here"

api = shodan.Shodan(SHODAN_API_KEY)

Searching Shodan

Now that we have our API object all good to go, we’re ready to perform a search:

# Wrap the request in a try/ except block to catch errors
try:
        # Search Shodan
        results = api.search('apache')

        # Show the results
        print 'Results found: %s' % results['total']
        for result in results['matches']:
                print 'IP: %s' % result['ip_str']
                print result['data']
                print ''
except shodan.APIError, e:
        print 'Error: %s' % e

Stepping through the code, we first call the Shodan.search() method on the api object which returns a dictionary of result information. We then print how many results were found in total, and finally loop through the returned matches and print their IP and banner. Each page of search results contains up to 100 results.

There’s a lot more information that gets returned by the function. See below for a shortened example dictionary that Shodan.search() returns:

{
        'total': 8669969,
        'matches': [
                {
                        'data': 'HTTP/1.0 200 OK\r\nDate: Mon, 08 Nov 2010 05:09:59 GMT\r\nSer...',
                        'hostnames': ['pl4t1n.de'],
                        'ip': 3579573318,
                        'ip_str': '89.110.147.239',
                        'os': 'FreeBSD 4.4',
                        'port': 80,
                        'timestamp': '2014-01-15T05:49:56.283713'
                },
                ...
        ]
}

Please visit the REST API documentation for the complete list of properties that the methods can return.

It’s also good practice to wrap all API requests in a try/ except clause, since any error will raise an exception. But for simplicity’s sake, I will leave that part out from now on.

Looking up a host

To see what Shodan has available on a specific IP we can use the Shodan.host() function:

# Lookup the host
host = api.host('217.140.75.46')

# Print general info
print """
        IP: %s
        Organization: %s
        Operating System: %s
""" % (host['ip_str'], host.get('org', 'n/a'), host.get('os', 'n/a'))

# Print all banners
for item in host['data']:
        print """
                Port: %s
                Banner: %s

        """ % (item['port'], item['data'])
