Port 5357 Hacktricks Jun 2026

is routinely flagged during internal network security assessments and infrastructure penetration tests. Typically identified by network scanners as hosting wsdapi or Microsoft-HTTPAPI/2.0 , this port plays an integral role in Windows local network ecosystems.

When assessing port 5357, the primary risk is information disclosure. By querying this port, an attacker can extract metadata about the target system without authentication. Tools such as ntbscan or custom scripts utilizing the Python impacket library can send a probe to the port and receive a response containing the computer name, workgroup, and operating system version. This is critical intelligence for an attacker; knowing the exact OS version allows them to tailor exploits specifically for that environment, bypassing generic defenses. The enumeration of this port aligns with the HackTricks philosophy of "trust but verify"—assuming a network is secure until an open port reveals that a machine is unnecessarily broadcasting its fingerprint. port 5357 hacktricks
