New Risk Assessment Score

Today we've introduced a new feature to the v2 API endpoint which allows you to get a risk score for an IP Address. This draws on the immense volume of attack data we have combined with our knowledge of active proxy servers and virtual private networks.

    "status": "ok",
    "node": "PROMETHEUS",
    "": {
        "asn": "AS45090",
        "provider": "Shenzhen Tencent Computer Systems Company Limited",
        "country": "China",
        "city": "Beijing",
        "latitude": 39.9288,
        "longitude": 116.3889,
        "isocode": "CN",
        "proxy": "yes",
        "type": "Compromised Server",
        "risk": 100,
        "last seen human": "56 minutes, 33 seconds ago",
        "last seen unix": "1551868636"
    "query time": "0.006s"

Above is an example query and just below the proxy and type responses you can see a new risk score. This can range from 0 to 100 and it's a percentage value. Anything below 33% is considered a low risk while between 34% and 66% is considered a high risk and anything between 67% and 100% is considered dangerous.

We've added this score so that you can glean more information about an IP, specifically how dangerous it is on top of the proxy yes/no determination. Scores will generally be between 66% and 100% for positive detections depending on how much bad activity we're witnessing from that IP while negative detections will generally be below 10%.

To access this new feature you must supply a new flag with your queries which is &risk=1 and please remember not to rely on this score to make all your determinations, we recommend you provision your software for proxy: yes/no although you may want to fine tune your blocking based on how risky the IP has been determined to be.
