Man in the middle attack detected on IOs device (IPhone 8)

Hello,

Thank you for reaching the community forum. This alert most likely came from a  Public Wifi or Hotspot. The attack has been stopped by Sophos mobile, so there's no harm to the device but for precaution, advise the users who get this alert to perform a password reset on their accounts which are currently log in to the device. 

There are many forms of man-in-the-middle attacks. Here are just a few:

Compromised public Wi-Fi. A hacker might eavesdrop on an unencrypted public Wi-Fi connection you’re using. Or they might create a fake public Wi-Fi hotspot (an “evil twin”) that mimics a legitimate hotspot. As soon as you log onto the fake hotspot, the hacker can intercept everything you send to a site and everything it sends back to you.

1. Use Virtual Private Networks (VPNs) when you’re in a public place.
2. Don’t visit sites that aren’t protected by secure HTTPS: look for HTTPS rather than HTTP in the web address. This isn’t foolproof, but it helps.
3. Please stay away from websites when your browser warns they’re unsafe.
4. Use multi-factor authentication on sites that offer you the option.
5. Don’t click email links or open attachments you aren’t expecting.

Ensure your home/office Wi-Fi network is protected with strong passwords and encryption. For example, use WPA2-PSK (AES) encryption, not WEP-64, WEP-128, or WPA-PSK.

And this is one of the nice things about having a Sophos Firewall: VPN back to your own home when you're out. No need to have a VPN service (and have to trust them).
