Passive hostname, domain and IP lookup tool for non-robots
wtfis is a commandline tool that gathers information about a domain, FQDN or IP address using various OSINT services. Unlike other tools of its kind, it's built specifically for human consumption, providing results that are pretty (YMMV) and easy to read and understand.
This tool assumes that you are using free tier / community level accounts, and so makes as few API calls as possible to minimize hitting quotas and rate limits.
The project name is a play on "whois".
| Service | Used in lookup | Required | Free Tier |
|---|---|---|---|
| Virustotal | All | Yes | Yes |
| Passivetotal | All | No | Yes |
| IP2Whois | Domain/FQDN | No | Yes |
| IPWhois | IP address | No | Yes (no signup) |
| Shodan | IP address | No | No |
| Greynoise | IP address | No | Yes |
| URLhaus | All | No | Yes (no signup) |
| AbuseIPDB | IP address | No | Yes |
The primary source of information. Retrieves:
- Hostname (FQDN), domain or IP
- Latest analysis stats with vendor detail
- Reputation score (based on VT community votes)
- Popularity ranks (Alexa, Cisco Umbrella, etc.) (FQDN and domain only)
- Categories (assigned by different vendors)
- Resolutions (FQDN and domain only)
- Last n IP addresses (default: 3, max: 10)
- Latest analysis stats of each IP above
- Whois
- Fallback only: if Passivetotal creds are not available
- Various whois data about the domain itself
Optionally used if creds are provided. Retrieves:
- Whois
- Various whois data about the domain itself
Passivetotal is recommended over Virustotal for whois data for a couple of reasons:
- VT whois data format is less consistent
- PT whois data tends to be of better quality than VT. Also, VT's registrant data is apparently anonymized.
- You can save one VT API call by offloading to PT
Optionally used if creds are provided and Passivetotal creds are not supplied. (i.e. second in line for Whois information)
- Whois
- Various whois data about the domain itself
As above, IP2Whois is recommended over Virustotal if a Passivetotal account cannot be obtained.
Default Geolocation and ASN lookup source for IP addresses. Retrieves:
- ASN, Org, ISP and Geolocation
IPWhois should not be confused with IP2Whois, which provides domain Whois data.
GETs data from the /shodan/host/{ip} endpoint (see doc). For each IP, retrieves:
- ASN, Org, ISP and Geolocation
- List of open ports and services
- Operating system (if available)
- Tags (assigned by Shodan)
Using Greynoise's community API, wtfis will show whether an IP is in one of Greynoise's datasets:
- Noise: IP has been seen regularly scanning the Internet
- RIOT: IP belongs to a common business application (e.g. Microsoft O365, Google Workspace, Slack)
More information about the datasets here.
In addition, the API also returns Greynoise's classification of an IP (if available). Possible values are benign, malicious, and unknown.
URLhaus is a crowd-sourced database of reported malicious URLs. This enrichment provides insight on whether the queried hostname or IP is being or was used for malware distribution via HTTP or HTTPS. Data that is provided include:
- Count of currently online and total malware URLs
- Whether the hostname or IP is currently in the DNSBL and SURBL public blocklists
- All tags that have been assigned to the URL throughout its history in the URLhaus database
AbuseIPDB is a crowd-sourced database of reported malicious IP addresses. Through its API wtfis shows:
- Abuse confidence score (0-100)
- Number of reports
$ pip install wtfis
To install via conda (from conda-forge), see wtfis-feedstock.
To install via brew:
brew install wtfis
wtfis uses these environment variables:
VT_API_KEY(required) - Virustotal API keyPT_API_KEY(optional) - Passivetotal API keyPT_API_USER(optional) - Passivetotal API userIP2WHOIS_API_KEY(optional) - IP2WHOIS API keySHODAN_API_KEY(optional) - Shodan API keyGREYNOISE_API_KEY(optional) - Greynoise API keyABUSEIPDB_API_KEY(optional) - AbuseIPDB API keyWTFIS_DEFAULTS(optional) - Default arguments
Set these using your own method.
Alternatively, create a file in your home directory ~/.env.wtfis with the above declarations. See .env.wtfis.example for a template. NOTE: Don't forget to chmod 400 the file!
usage: wtfis [-h] [-m N] [-s] [-g] [-a] [-u] [-n] [-1] [-V] entity
positional arguments:
entity Hostname, domain or IP
optional arguments:
-h, --help show this help message and exit
-m N, --max-resolutions N
Maximum number of resolutions to show (default: 3)
-s, --use-shodan Use Shodan to enrich IPs
-g, --use-greynoise Enable Greynoise for IPs
-a, --use-abuseipdb Enable AbuseIPDB for IPs
-u, --use-urlhaus Enable URLhaus for IPs and domains
-n, --no-color Show output without colors
-1, --one-column Display results in one column
-V, --version Print version number
Basically:
$ wtfis FQDN_OR_DOMAIN_OR_IP
and you will get results organized by panel, similar to the image above.
Defanged input is accepted (e.g. api[.]google[.]com).
If supported by the terminal, the Analysis field and (if using PT) headings in the whois panel are clickable hyperlinks that point to the appropriate pages on the VT or PT website.
Shodan can be used to enrich the IP addresses (instead of IPWhois). Invoke with the -s or --use-shodan flag.
If supported by the terminal, the Services field is a clickable hyperlink that takes you to the Shodan web interface.
To enable Greynoise, invoke with the -g or --use-greynoise flag. Because the API quota is quite low (50 requests per week as of March 2023), this lookup is off by default.
The GreyNoise field name is also a hyperlink (if terminal-supported) that points to the IP entry in the Greynoise web interface, where more context is shown.
Use the -u or --use-urlhaus flag to enable URLhaus enrichment for hostnames, domains and IPs.
The Malware URLs field name is a hyperlink (if terminal-supported) that takes you to the specific URLhaus database page for your query.
Use the -a or --use-abuseipdb flag to enable AbuseIPDB enrichment for hostnames, domains and IPs.
The AbuseIPDB field name is a hyperlink (if terminal-supported) that takes you to the specific AbuseIPDB database page for your query.
For FQDN and domain lookups, you can increase or decrease the maximum number of displayed IP resolutions with -m NUMBER or --max-resolutions=NUMBER. The upper limit is 10. If you don't need resolutions at all, set the number to 0.
To show all panels in one column, use the -1 or --one-column flag.
Panels can be displayed with no color with -n or --no-color.
Default arguments can be defined by setting the WTFIS_DEFAULTS environment variable. For example, to use shodan and display results in one column by default:
WTFIS_DEFAULTS=-s -1
If an argument is in WTFIS_DEFAULTS, then specifying the same argument during command invocation negates that argument. So in the example above, if you then run:
$ wtfis example.com -s
then Shodan will NOT be used.
Note that maximum resolutions (-m N, --max-resolutions N) cannot be defined in defaults at the moment.
wtfis can be run from a Docker image. First, build the image (using the included Dockerfile) by running:
$ make docker-image
The image will have the latest tagged version (not necessarily from the latest commit) wtfis. This ensures that you are getting a stable release.
Two ways you can run the image:
Ensure .env.wtfis is in your home directory and set with the necessary envvars. Then simply run:
$ make docker-run
This is an alias to
$ docker run --env-file=${HOME}/.env.wtfis -it wtfis
Note that each definition must NOT have any spaces before and after the equal sign (FOO=bar, not FOO = bar).
Altenatively, you can set the environment variables yourself, then run, e.g.:
$ docker run -e VT_API_KEY -e SHODAN_API_KEY -it wtfis
