Overview

This tool analyzes first stage of TCP handshake (SYN) and recognize operating system of client

Build

To build sp0ky, you need to install Rust

git clone https://github.com/MOL0ToK/sp0ky.git
cd sp0ky
cargo build --release

./target/release/sp0ky

Run

sudo sp0ky -i <interface>

Run in docker

To access host network interfaces, you should run docker container in host network mode

docker run --net=host -e SP0KY_INTERFACE=<interface> mol0tok/sp0ky:latest

API usage

To get connection information, you can use the API on port 7564.

Request:

curl http://localhost:7564/111.111.111.111:53155

Response with result:

{"os":"Windows","signature":"4:116+12:0:1360:64240:8:mss,nop,ws,nop,nop,sok:10:000000010"}

Or without:

{}

Fingerprint (signature)

In addition to operating system information, this tool generates a fingerprint that you can use for additional processing.

Fingerprint format: IP_VERSION:TTL+HOPS:IP_OPTIONS_LENGTH:MSS:TCP_WINDOW_SIZE:TCP_WINDOW_SCALE:TCP_OPTIONS:IP_FLAGS:TCP_FLAGS

Example: 4:116+12:0:1360:64240:8:mss,nop,ws,nop,nop,sok:10:000000010
