# WHATPORT(27353)

## NAME

port 27353 — Unassigned — Unassigned by IANA; unnamed in Nmap's table and usually reported next to 27352.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA places 27353 in the unassigned block 27346-27441. Nmap lists it as 'unknown' with an open-frequency close to that of 27352, 27355 and 27356, so the four show up as a cluster in scan results without any of them being identified. No product default, protocol, or documented malware family claims this number. Read the banner, not the port.

## EXPOSURE

**Expose with care.** Nothing standard listens here. Fingerprint the service and apply its rules rather than the port's.

## CHECK

```sh
nmap -Pn -sV -p 27353 --reason TARGET
```
