Technical Details

what runs on :7743

SSTP is an HTTP-like, text-based request/response protocol: clients send a method and headers (often including sender, event, or script information), and the application returns a status response. It is commonly used over TCP and is generally a local inter-process interface, not an encrypted network protocol; the familiar default in Ukagaka implementations is TCP port 9801. IANA lists 7743 for both TCP and UDP, but that registration does not establish that UDP implementations use the same framing or are commonly deployed on this port.

security overview

An exposed SSTP listener may accept requests that trigger supported events or scripts in the desktop-mascot application. It is intended primarily for local software interaction, so avoid exposing it to untrusted networks; traffic is not encrypted by default. The port is rarely observed open, and no specific widely exploited vulnerability is established here.

Record

iana registry entry

port: :7743
service: Sakura Script Transfer Protocol
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services System
usage: SSTP is used by Ukagaka (desktop mascot) software for clients to send events or scripts to a running character application. IANA assigns it to TCP and UDP port 7743, but common implementations are associated with TCP port 9801, so 7743 is not a port commonly encountered open.
