If this was a Windows machine, and if it was chatty, she could force it to identify itself.
An open 5357 often signals a Windows environment where "Network Discovery" is enabled for "Private" or "Domain" firewall profiles. ⚠️ Potential Vulnerabilities port 5357 hacktricks
In the landscape of cybersecurity and penetration testing, open ports are the gateway to potential compromise. While high-profile ports like 22 (SSH), 80 (HTTP), and 445 (SMB) garner the most attention, lesser-known service ports often provide the stealthy footholds that attackers exploit. One such vector is TCP port 5357, associated with the Web Services for Devices (WSD) and the Link-Local Multicast Name Resolution (LLMNR) protocol suite. In security resources like HackTricks, this port is highlighted not necessarily for a single catastrophic vulnerability, but as a significant information disclosure vector and a relic of convenience that creates unnecessary network exposure in modern Windows environments. If this was a Windows machine, and if
Port 5357 is a UDP port used by the Windows operating system for the Windows Remote Management (WinRM) service, also known as the Microsoft Management Console (MMC) or Windows Management Instrumentation (WMI). It's also used for the Simple Network Management Protocol (SNMP) and other management applications. While high-profile ports like 22 (SSH), 80 (HTTP),
