Threat Intelligence APIs.

Supported threat intelligence feeds

The package contains API wrappers for:

Umbrella Investigate API
VirusTotal API v2.0
ShadowServer API

Umbrella Investigate API

Umbrella Investigate provides an API that allows querying for:

Domain categorization
Security information about a domain
Co-occurrences for a domain
Related domains for a domain
Domains related to an IP
Domain tagging dates for a domain
DNS RR history for a domain
WHOIS information
- WHOIS information for an email
- WHOIS information for a nameserver
- Historical WHOIS information for a domain
Latest malicious domains for an IP

To use the Investigate API wrapper import InvestigateApi class from threat_intel.opendns module:

from threat_intel.opendns import InvestigateApi

To initialize the API wrapper you need the API key:

investigate = InvestigateApi("<INVESTIGATE-API-KEY-HERE>")

You can also specify a file name where the API responses will be cached in a JSON file, to save you the bandwidth for the multiple calls about the same domains or IPs:

investigate = InvestigateApi("<INVESTIGATE-API-KEY-HERE>", cache_file_name="/tmp/cache.opendns.json")

Domain categorization

Calls domains/categorization/?showLabels Investigate API endpoint. It takes a list (or any other Python enumerable) of domains and returns the categories associated with this domains by Umbrella along with a [-1, 0, 1] score, where -1 is a malicious status.

domains = ["google.com", "baidu.com", "bibikun.ru"]
investigate.categorization(domains)

will result in:

{
    "baidu.com": {"status": 1, "content_categories": ["Search Engines"], "security_categories": []},
    "google.com": {"status": 1, "content_categories": ["Search Engines"], "security_categories": []},
    "bibikun.ru": {"status": -1, "content_categories": [], "security_categories": ["Malware"]}
}

Security information about a domain

Calls security/name/ Investigate API endpoint. It takes any Python enumerable with domains, e.g. list, and returns several security parameters associated with each domain.

investigate.security(domains)

will result in:

VirusTotal API

VirusTotal provides an API that makes it possible to query for the reports about:

* Domains
* URLs
* IPs
* File hashes
* File Upload
* Live Feed
* Advanced search

To use the VirusTotal API wrapper import VirusTotalApi class from threat_intel.virustotal module:

from threat_intel.virustotal import VirusTotalApi

To initialize the API wrapper you need the API key:

vt = VirusTotalApi("<VIRUSTOTAL-API-KEY-HERE>")

VirusTotal API calls allow to squeeze a list of file hashes or URLs into a single HTTP call. Depending on the API version you are using (public or private) you may need to tune the maximum number of the resources (file hashes or URLs) that could be passed in a single API call. You can do it with the resources_per_req parameter:

vt = VirusTotalApi("<VIRUSTOTAL-API-KEY-HERE>", resources_per_req=4)

When using the public API your standard request rate allows you too put maximum 4 resources per request. With private API you are able to put up to 25 resources per call. That is also the default value if you don't pass the resources_per_req parameter.

Of course when calling the API wrapper methods in the VirusTotalApi class you can pass as many resources as you want and the wrapper will take care of producing as many API calls as necessary to satisfy the request rate.

You can also specify the file name where the responses will be cached:

vt = VirusTotalApi("<VIRUSTOTAL-API-KEY-HERE>", cache_file_name="/tmp/cache.virustotal.json")
