fingerprintx is a utility similar to httpx that also supports fingerprinting services like as RDP, SSH, MySQL, PostgreSQL, Kafka, etc. fingerprintx can be used alongside port scanners like Naabu to fingerprint a set of ports identified during a port scan. For example, an engineer may wish to scan an IP range and then rapidly fingerprint the service running on all the discovered ports.
51 service detection plugins supporting TCP and UDP protocols:
From Github
go install github.com/praetorian-inc/fingerprintx/cmd/fingerprintx@latest
From source (go version > 1.18)
$ git clone [email protected]:praetorian-inc/fingerprintx.git
$ cd fingerprintx
# with go version > 1.18
$ go build ./cmd/fingerprintx
$ ./fingerprintx -h
Docker
$ git clone [email protected]:praetorian-inc/fingerprintx.git
$ cd fingerprintx
# build
docker build -t fingerprintx .
# and run it
docker run --rm fingerprintx -h
docker run --rm fingerprintx -t praetorian.com:80 --json
fingerprintx -h
The -h option will display all of the supported flags for fingerprintx.

The fast mode will only attempt to fingerprint the default service associated with that port for each target. For example, if praetorian.com:8443 is the input, only the https plugin would be run. If https is not running on praetorian.com:8443, there will be NO output. Why do this? It's a quick way to fingerprint most of the services in a large list of hosts (think the 80/20 rule).
With one target:
$ fingerprintx -t 127.0.0.1:8000
http://127.0.0.1:8000
By default, the output is in the form: SERVICE://HOST:PORT. To get more detailed service output specify JSON with the --json flag:
$ fingerprintx -t 127.0.0.1:8000 --json
{"ip":"127.0.0.1","port":8000,"service":"http","transport":"tcp","metadata":{"responseHeaders":{"Content-Length":["1154"],"Content-Type":["text/html; charset=utf-8"],"Date":["Mon, 19 Sep 2022 18:23:18 GMT"],"Server":["SimpleHTTP/0.6 Python/3.10.6"]},"status":"200 OK","statusCode":200,"version":"SimpleHTTP/0.6 Python/3.10.6"}}
Pipe in output from another program (like naabu):
$ naabu 127.0.0.1 -silent 2>/dev/null | fingerprintx
http://127.0.0.1:8000
ftp://127.0.0.1:21
Run with an input file:
$ cat input.txt | fingerprintx
http://praetorian.com:80
telnet://telehack.com:23
# or if you prefer
$ fingerprintx -l input.txt
http://praetorian.com:80
telnet://telehack.com:23
With more metadata output:
$ cat input.txt | fingerprintx --json
{"host":"praetorian.com","ip":"146.148.61.165","port":80,"service":"http","transport":"tcp","metadata":{"responseHeaders":{"Connection":["keep-alive"],"Content-Type":["text/html"],"Date":["Mon, 19 Sep 2022 18:37:55 GMT"],"Etag":["W/\"5e3e263f-1703\""],"Keep-Alive":["timeout=20"],"Server":["nginx"],"Vary":["Accept-Encoding"]},"status":"404 Not Found","statusCode":404,"version":"nginx"}}
{"host":"telehack.com","ip":"64.13.139.230","port":23,"service":"telnet","transport":"tcp","metadata":{"serverData":"fffb03"}}
fingerprintx can be imported into your project to scan for services on open ports. Example code on how one might do this is provided here in the examples directory. Build with go build scan.go. Another file that might be of use as a reference when importing fingerprintx into your own project is the command line runner.
Nmap is the standard for network scanning. Why use fingerprintx instead of nmap? The main two reasons are:
fingerprintx works smarter, not harder: the first plugin run against a server with port 8080 open is the http plugin. The default service approach cuts down scanning time in the best case. Most of the time the services running on port 80, 443, 22 are http, https, and ssh -- so that's what fingerprintx checks first.fingerprintx supports json output with the --json flag. Nmap supports numerous output options (normal, xml, grep), but they are often hard to parse and script appropriately. fingerprintx supports json output which eases integration with other tools in processing pipelines.third_party folder that imports the Go cryptography libraries?ssh fingerprinting module identifies the various cryptographic options supported by the server when collecting metadata during the handshake process. This makes use of a few unexported functions, which is why the Go cryptography libraries are included here with an export.go file.target:port input is open. If none of the ports are open there will be no output as there are no services running on the targets.zgrab2 command line usage (and use case) is slightly different than fingerprintx. For zgrab2, the protocol must be specified ahead of time: echo praetorian.com | zgrab2 http -p 8000, which assumes you already know what is running there. For fingerprintx, that is not the case: echo praetorian.com:8000 | fingerprintx. The "application layer" protocol scanning approach is very similar.fingerprintx is the work of a lot of people, including our great intern class of 2022. Here is a list of contributors so far:
