# WHATPORT(62078)

## NAME

port 62078 — iOS lockdownd (device pairing/sync) — An iPhone or iPad: lockdownd, the service behind pairing, sync, and backup.

Protocol: TCP

## DESCRIPTION

lockdownd is the iOS service that brokers every other device service — backup, installation, diagnostics, screenshots — and it is reachable on TCP 62078, over USB through usbmuxd and over Wi-Fi when Wi-Fi sync is enabled. It is the single most reliable way to identify an iOS device on a network scan, since it is a fixed port in the dynamic range that Apple never registered with IANA. Tools like libimobiledevice (idevicepair, idevicebackup2) talk to exactly this port.

## EXPOSURE

**Do not expose.** Anything that reaches lockdownd can attempt to pair with the device, and a valid pairing record grants broad access to its data — this should never leave the local link, let alone the LAN.

## CHECK

```sh
nc -vz -w 3 IPHONE_IP 62078
```
