Threat Intelligence APIs.




## Supported threat intelligence feeds

The package contains API wrappers for:

* OpenDNS Investigate API
* VirusTotal API v2.0
* ShadowServer API


----

### OpenDNS Investigate API

[OpenDNS Investigate](https://investigate.opendns.com/) provides an API that
allows querying for:
* Domain categorization
* Security information about a domain
* Related domains (cooccurrences)
* Domains related to an IP

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

```python
from threat_intel.opendns import InvestigateApi
```

To initialize the API wrapper you need the API key:

```python
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:

```python
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 OpenDNS.

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

will result in:

```json
{
"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 security parameters
associated with each domain.

```python
domains = ["google.com", "baidu.com", "bibikun.ru"]
investigate.security(domains)
```

will result in:

```json
{
"baidu.com": {
"found": true,
"handlings": {
"domaintagging": 0.00032008666962131285,
"blocked": 0.00018876906157154347,
"whitelisted": 0.00019697641207465407,
"expired": 2.462205150933176e-05,
"normal": 0.9992695458052232
},
"dga_score": 0,
"rip_score": 0,

..

}
}
```


#### Related domains (cooccurrences)

Calls `recommendations/name/` Investigate API endpoint.
Use this method to find out related domains to the one given in a list, or any other Python enumerable.

```python
domains = ["google.com", "baidu.com", "bibikun.ru"]
investigate.cooccurrences(domains)
```

will result in:

```json
{
"baidu.com": {
"found": true,
"pfs2": [
["www.howtoforge.de", 0.14108563836506008],

..

}
```


#### Domains related to an IP

Calls `dnsdb/ip/a/` Investigate API endpoint.
Use this method to find out related domains to the IP addresses given in a list, or any other Python enumerable.

```python
ips = ['8.8.8.8']
investigate.rr_history(ips)
```

will result in:

```json
{
"8.8.8.8": {
"rrs": [
{
"name": "8.8.8.8",
"type": "A",
"class": "IN",
"rr": "000189.com.",
"ttl": 3600
},
{
"name": "8.8.8.8",
"type": "A",
"class": "IN",
"rr": "008.no-ip.net.",
"ttl": 60
},

..

}
```

### VirusTotal API

[VirusTotal](https://www.virustotal.com/) provides an
[API](https://www.virustotal.com/en/documentation/public-api/) that makes it
possible to query for the reports about:
* File hashes
* Domains
* URLs

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

```python
from threat_intel.virustotal import VirusTotalApi
```

To initialize the API wrapper you need the API key:

```python
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:

```python
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.

Similarly to OpenDNS API wrapper, you can also specify the file name where the responses will be cached:

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


#### File hash reports

Calls `file/report` VirusTotal API endpoint.
You can request the file reports passing a list of hashes (md5, sha1 or sha2):

```python
file_hashes = [
"99017f6eebbac24f351415dd410d522d",
"88817f6eebbac24f351415dd410d522d"
]

vt.get_file_reports(file_hashes)
```

will result in:

```json
{
"88817f6eebbac24f351415dd410d522d": {
"response_code": 0,
"resource": "88817f6eebbac24f351415dd410d522d",
"verbose_msg": "The requested resource is not among the finished, queued or pending scans"
},
"99017f6eebbac24f351415dd410d522d": {
"scan_id": "52d3df0ed60c46f336c131bf2ca454f73bafdc4b04dfa2aea80746f5ba9e6d1c-1423261860",
"sha1": "4d1740485713a2ab3a4f5822a01f645fe8387f92",

..

}
```


#### Domain reports

Calls `domain/report` VirusTotal API endpoint.
Pass a list or any other Python enumerable containing the domains:

```python
domains = ["google.com", "baidu.com", "bibikun.ru"]
vt.get_domain_reports(domains)
```

will result in:

```json
{
"baidu.com": {
"undetected_referrer_samples": [
{
"positives": 0,
"total": 56,
"sha256": "e3c1aea1352362e4b5c008e16b03810192d12a4f1cc71245f5a75e796c719c69"
}
],

..

}
```

#### IP reports

Calls `ip-address/report` VirusTotal API endpoint.
Pass a list or any other Python enumerable containing the IP addresses:

```python
ips = ['90.156.201.27', '198.51.132.80']
vt.get_ip_reports(ips)
```

will result in:

```json
{
"90.156.201.27": {
"asn": "25532",
"country": "RU",
"response_code": 1,
"as_owner": ".masterhost autonomous system",
"verbose_msg": "IP address found in dataset",
"resolutions": [
{
"last_resolved": "2013-04-01 00:00:00",
"hostname": "027.ru"
},
{
"last_resolved": "2015-01-20 00:00:00",
"hostname": "600volt.ru"
},

..

],
"detected_urls": [
{
"url": "http://shop.albione.ru/",
"positives": 2,
"total": 52,
"scan_date": "2014-04-06 11:18:17"
},
{

"scan_date": "2014-03-05 09:13:31"
}
],
},

"198.51.132.80": {

..

}
}
```

#### URL reports

Calls `url/report` VirusTotal API endpoint.
Pass a list or any other Python enumerable containing the URL addresses:

```python
urls = ["http://www.google.com", "http://www.yelp.com"]
vt.get_url_reports(urls)
```

will result in:

```json
{
"http://www.google.com": {
"permalink": "https://www.virustotal.com/url/dd014af5ed6b38d9130e3f466f850e46d21b951199d53a18ef29ee9341614eaf/analysis/1423344006/",

"positives": 0,
"total": 62,
"scans": {
"CLEAN MX": {

},

..

}
```

### ShadowServer API

[ShadowServer](http://shadowserver.org/) provides and [API](http://bin-test.shadowserver.org/) that allows to test
the hashes against a list of known software applications.

To use the ShadowServer API wrapper import `ShadowServerApi` class from `threat_intel.shadowserver` module:

```python
from threat_intel.shadowserver import ShadowServerApi
```

To use the API wrapper simply call the `ShadowServerApi` initializer:

```python
ss = ShadowServerApi()
```

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

```python
ss = ShadowServerApi(cache_file_name="/tmp/cache.shadowserver.json")
```

To check whether the hashes are on the ShadowServer list of known hashes,
call `get_bin_test` method and pass enumerable with the hashes you want to test:

```python
file_hashes = [
"99017f6eebbac24f351415dd410d522d",
"88817f6eebbac24f351415dd410d522d"
]

ss.get_bin_test(file_hashes)

```
