Unassigned, and one of four nearby ports in the same block that scanners keep finding open.
27352 sits in IANA's unassigned range 27346-27441, alongside 27353, 27355 and 27356 — all four carry 'unknown' entries with similar open-frequencies in Nmap's table, which is why they tend to appear together in scan output. The same block also contains 27374, the port historically associated with the SubSeven Windows backdoor, but that association belongs to 27374 alone and does not extend to its neighbours. Nothing is registered or documented for 27352 itself.
