 ## Basic Information
 
-**SOCKS** is a protocol used for transferring data between a client and server through a proxy. The fifth version, **SOCKS5**, adds an optional authentication feature, allowing only authorized users to access the server. It primarily handles the proxying of TCP connections and the forwarding of UDP packets, operating at the session layer (Layer 5) of the OSI model.
+**SOCKS** is a protocol used for transferring data between a client and server through a proxy. The fifth version, **SOCKS5**, adds an optional authentication feature, allowing only authorized users to access the server. It primarily handles the proxying of TCP connections and the forwarding of UDP packets (via the `UDP ASSOCIATE` command), operating at the session layer (Layer 5) of the OSI model. When tooling supports the `socks5h` scheme, DNS resolution is forced through the proxy, preventing local DNS leaks and making it harder to fingerprint the originating host.

-Edit the bottom and add your proxy
+`socks-methods` forces the server to list supported authentication types, while `socks-open-proxy` attempts an outbound CONNECT to confirm whether the service can be abused as a relay.

+#### Raw handshake check
+
+```bash
+printf '\x05\x01\x00' | nc -nv <ip> 1080
 ```
 
-With auth
+A `\x05 01 00` response indicates SOCKS5 offering "no authentication". Any `\x00` followed by `\x02` means username/password is required, which is useful for quickly fingerprinting exposed devices in scripts.
 
+### Quick egress validation
+
+```bash
+curl --socks5-hostname <ip>:1080 https://ifconfig.me
+curl --socks5-hostname user:pass@<ip>:1080 http://internal.target
 ```
-socks5 10.10.10.10 1080 username password
+
+Use `--socks5-hostname` (or `socks5h://` URLs) so DNS resolution happens remotely. Pair it with `proxychains4 -q nmap -sT -Pn --top-ports 200 <internal-host>` to verify whether the proxy truly provides internal reach.
