GNQL Query

GreyNoise Query Language

GNQL (GreyNoise Query Language) is a domain-specific query language that uses Lucene deep under the hood. GNQL aims to enable GreyNoise Enterprise and Research users to make complex and one-off queries against the GreyNoise dataset as new business cases arise. GNQL is built with self-defeat and fully featured product lines in mind. If we do our job correctly, each individual GNQL query that brings our users and customers sufficient value will eventually be transitioned into it's own individual offering.

Facets:

• ip - The IP address of the scanning device IP
• classification - Whether the device has been categorized as unknown, benign, or malicious
• first_seen - The date the device was first observed by GreyNoise
• last_seen - The date the device was most recently observed by GreyNoise
• actor - The benign actor the device has been associated with, such as Shodan, Censys, GoogleBot, etc
• tags - A list of the tags the device has been assigned over the past 90 days
• spoofable - This IP address has been opportunistically scanning the Internet, however has failed to complete a full TCP connection. Any reported activity could be spoofed.
• vpn - This IP is associated with a VPN service. Activity, malicious or otherwise, should not be attributed to the VPN service provider.
• vpn_service - The VPN service the IP is associated with
• cve - A list of CVEs that the device has been associated with

• metadata.category - Whether the device belongs to a business, isp, hosting, education, or mobile network
• metadata.country - The full name of the country the device is geographically located in (This is the same data as metadata.source_country. metadata.source_country is preferred)
• metadata.country_code - The two-character country code of the country the device is geographically located in (This is the same data as metadata.source_country_code. metadata.source_country_code is preferred)
• metadata.sensor_hits - The amount of unique data that has been recorded by the sensor

• metadata.city - The city the device is geographically located in
• metadata.region - The region the device is geographically located in
• metadata.organization - The organization that owns the network that the IP address belongs to
• metadata.rdns - The reverse DNS pointer of the IP
• metadata.asn - The autonomous system the IP address belongs to
• metadata.tor - Whether or not the device is a known Tor exit node
• metadata.destination_countries - The full country name where the GreyNoise sensors are physically located
• metadata.destination_country_codes - The country code where the GreyNoise sensors are physically located
• metadata.destination_country - The full country name where the GreyNoise sensors are physically located
• metadata.destination_country_code - The country code where the GreyNoise sensors are physically located
• metadata.source_country_code - The two-character country code of the country the device is geographically located in
• metadata.source_country - The full name of the country the device is geographically located in
• raw_data.scan.port - The port number(s) the devices has been observed scanning
• raw_data.scan.protocol - The protocol of the port the device has been observed scanning
• raw_data.web.paths - Any HTTP paths the device has been observed crawling the Internet for
• raw_data.web.useragents - Any HTTP user-agents the device has been observed using while crawling the Internet
• raw_data.ja3.fingerprint - The JA3 TLS/SSL fingerprint
• raw_data.ja3.port - The corresponding TCP port for the given JA3 fingerprint
• raw_data.hassh.fingerprint - The HASSH fingerprint
• raw_data.hassh.port - The corresponding TCP port for the given HASSH fingerprint

Behavior:

• You can subtract facets by prefacing the query with a minus character
• The data that this endpoint queries refreshes once per hour

Shortcuts:

• You can find interesting hosts by using the GNQL query term interesting
• You can use the keyword today in the first_seen and last_seen parameters: last_seen:today or first_seen:today

Examples:

• last_seen:today - Returns all IPs scanning/crawling the Internet today
• tags:Mirai - Returns all devices with the "Mirai" tag
• tags:"RDP Scanner" - Returns all devices with the "RDP Scanner" tag
• classification:malicious metadata.country:Belgium

• Returns all compromised devices located in Belgium

• classification:malicious metadata.rdns:*.gov* - Returns all compromised devices that include .gov in their reverse DNS records
• metadata.organization:Microsoft classification:malicious

• Returns all compromised devices that belong to Microsoft

• (raw_data.scan.port:445 and raw_data.scan.protocol:TCP) metadata.os:Windows* - Return all devices scanning the Internet for port 445/TCP running Windows operating systems (Conficker/EternalBlue/WannaCry)
• raw_data.scan.port:554 - Returns all devices scanning the Internet for port 554
• -metadata.organization:Google raw_data.web.useragents:GoogleBot

• Returns all devices crawling the Internet with "GoogleBot" in their useragent from a network that does NOT belong to Google

• tags:"Siemens PLC Scanner" -classification:benign - Returns all devices scanning the Internet for SCADA devices who ARE NOT tagged by GreyNoise as "benign" (Shodan/Project Sonar/Censys/Google/Bing/etc)
• classification:benign - Returns all "good guys" scanning the Internet
• raw_data.ja3.fingerprint:795bc7ce13f60d61e9ac03611dd36d90

• Returns all devices crawling the Internet with a matching client JA3 TLS/SSL fingerprint

• raw_data.hassh.fingerprint:51cba57125523ce4b9db67714a90bf6e

• Returns all devices crawling the Internet with a matching client HASSH fingerprint

• raw_data.web.paths:"/HNAP1/" -Returns all devices crawling the Internet for the HTTP path "/HNAP1/"
• 8.0.0.0/8 - Returns all devices scanning the Internet from the CIDR block 8.0.0.0/8
• cve:CVE-2021-30461 - Returns all devices associated with the supplied CVE
• source_country:Iran - Returns all results originating from Iran
• destination_country:Ukraine single_destination:true

• Returns all results scanning in only Ukraine

Search Usage: This endpoint consumes one Search per IP included in the response DATA object.
