Technical Details

what runs on :5360

IANA assigns TCP and UDP port 5360 to the Windows SideShow protocol. SideShow lets a Windows host exchange information with a companion device, such as a small auxiliary display; devices could connect through supported transports including network connections. The assignment identifies the protocol but does not specify a universal handshake, packet framing, or default listener behavior, so those details depend on the SideShow implementation. This is not a general-purpose web or remote-administration service, and an open port should be interpreted in the context of a SideShow-capable Windows host or device.

security overview

SideShow is a legacy, niche feature and this port is not expected to be exposed to the public internet. If reachable, an attacker could probe the implementation and attempt to exploit weaknesses in the host or device; restrict access to trusted local networks and disable the feature if unused. Do not assume traffic is encrypted by default.
