The exploit uses a combination of two weaknesses discovered in iOS, reports

<p>The first is that iOS devices automatically reconnect to known Wi-Fi hotspots, but rely on the SSID to identity them. iPhones and iPads will auto-connect to a malicious Wi-Fi hotspot that spoofs the name of a known one.</p>
<p>Second, iOS devices are programmed to constantly check that their time and date settings are correct by connecting to Network Time Protocol (NTP) servers. All the researchers had to do was create their own Wi-Fi hotspot labelled ‘attwifi’ (as used by Starbucks) and their own NTP server pretending to be time.apple.com to deliver the January 1, 1970 date …</p>
