# WHATPORT(1053)

## NAME

port 1053 — Remote Assistant (RA) — Registered to a product called Remote Assistant; no public spec, and no relation to Microsoft Remote Assistance.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1053 to `remote-as`, "Remote Assistant (RA)", a vendor registration with no published protocol description. It is not Microsoft's Remote Assistance, which rides RDP on 3389 and does not use this port. There is nothing more that can be established about the registered service beyond the registry entry itself. Because 1053 sits one digit off DNS's 53, it also turns up as an arbitrary local port for DNS forwarders and resolver test setups, which is a naming coincidence rather than a protocol fact.

## EXPOSURE

**Expose with care.** A registration name containing "remote" is a hint, not evidence. Fingerprint the listener; if it turns out to be a remote-control or admin service, it belongs behind a VPN.

## CHECK

```sh
nmap -Pn -sV -p 1053 TARGET
```
