Port 5357 Hacktricks Now

Port 5357 is commonly used for the Web Services Dynamic Discovery (WS-Discovery) provider host. Windows operating systems utilize this port to locate other devices, such as printers and network shares, on a local network using the Web Services on Devices (WSD) API.

Disable the underlying services via Group Policy Object (GPO) or the services console: Stop and disable . Stop and disable Function Discovery Resource Publication .

Poorly secured WSD services can expose printer admin pages, allowing attackers to manipulate or intercept print jobs. Lateral Movement:

Web Services Dynamic Discovery (WS-Discovery / WSDAPI)

Stop and disable the ( FDResPub ) service. Via PowerShell: powershell port 5357 hacktricks

Forcing the Windows machine to authenticate against an attacker’s Rogue SMB/HTTP server (e.g., Responder), allowing the collection or relaying of NetNTLMv2 hashes. Denial of Service (DoS)

Use specialized tools that understand WS-Discovery to query the service for device descriptions. 3. Security Risks and Potential Exploitation

If the service must remain active for local device discovery (such as office printing), ensure that Port 5357 is strictly blocked at the network perimeter firewall and restricted to trusted local subnets via the Windows Defender Firewall. Port 5357 is commonly used for the Web

: While there are no widespread "one-click" exploits for Port 5357 itself, it increases the target's attack surface by confirming the operating system and potentially leaking internal metadata about connected hardware.

Port 5357 is primarily associated with Web Services for Devices (WSDAPI)

The first step is identifying if port 5357 is open on a target system. A standard scan can quickly reveal the service:

Some WSD services expose management web pages (admin panels) of printers. Stop and disable Function Discovery Resource Publication

In high-security environments, consider replacing WSD with more authenticated protocols like IPP (Internet Printing Protocol) or LPD .

Stop and disable the ( fdphost ) service.
