According to HackTricks, a website known for providing detailed guides on penetration testing and cybersecurity: port 5357 hacktricks
If the target is a physical device (like a multi-function printer), interacting with the WSD API can expose: Device manufacturer and model numbers. Firmware versions. Configured network shares or destination folders. 4. Attack Surface and Lateral Movement
Port 5357 is used by for device discovery and control (e.g., network scanners, printers, media servers). It's part of WSD (Web Services on Devices) — Microsoft's implementation of devices profile for web services (DPWS).
The first step is identifying if port 5357 is open on a target system. A standard scan can quickly reveal the service: Operational guidance for red teams and defenders :
Start or Impacket's smbserver.py on your attack machine: sudo responder -I eth0 -dwv Use code with caution.
The listener captures or relays the NetNTLM hash to another service (like SMB or LDAP) to gain unauthorized access. Defensive Measures and Hardening
The use of port 5357 for remote management and execution of commands makes it an attractive target for hackers. By exploiting vulnerabilities or misconfigurations associated with this port, attackers can gain unauthorized access to sensitive information, execute malicious code, or even take control of the targeted system. Firmware versions
Stop-Service -Name "fdphost" -Force Set-Service -Name "fdphost" -StartupType Disabled Use code with caution. 2. Firewall Restrictions
Disable or restrict inbound traffic on port 5357 using Windows Defender Firewall unless explicitly required for network discovery (e.g., dedicated print servers).
An attacker triggers a request from port 5357 to an internal listener.
