Is it safe to use airbnb wifi to restore iCloud back up

Backing up your iPhone over unsecured Wi-Fi networks, such as those found in hotels or Airbnb accommodations, carries some security risks. While the risks are generally lower when compared to activities like logging into sensitive accounts, there are still potential vulnerabilities to consider:

1. When you back up your iPhone over an unsecured Wi-Fi network, the data being transferred, including your apps, settings, and possibly personal information, might be intercepted by malicious individuals. This could lead to the exposure of your private data.
2. If you are using iCloud Backup, your Apple ID and iCloud credentials are involved in the process. Transmitting these credentials over unsecured networks could put them at risk of being stolen.
3. Backing up your iPhone includes a range of data, from photos and videos to app data. If intercepted, this information could be used maliciously or even lead to identity theft.
4. Unsecured networks provide an avenue for cybercriminals to eavesdrop on your online activities. This includes monitoring the backup process and potentially gaining access to sensitive information.
5. Cyber attackers could position themselves between your device and the network, potentially altering or intercepting your backup data.

In summary, while it's not advisable to perform iPhone backups over unsecured Wi-Fi networks due to potential security risks.

Try backing up over mobile data. You can utilize your mobile data to back up your data on iCloud. I'm uncertain as to why you prefer to use a hotspot instead.
