7) Attackers Will Find New Vulnerabilities in the 5G/Wi-Fi Handover to Access the Voice and/or<br />

Data of 5G Mobile Phones<br />

The newest cellular standard, 5G, is rolling out across the world and promises big improvements in speed<br />

and reliability. Unknown to most people, in large public areas like hotels, shopping centers, and airports,<br />

your voice and data information of your cellular-enabled device is communicated to both cell towers and<br />

to Wi-Fi access points located throughout these public areas. Large mobile carriers do this to save<br />

network bandwidth in high-density areas. Your devices have intelligence built into them to automatically<br />

and silently switch between cellular and Wi-Fi. Security researches have exposed some flaws in this<br />

cellular-to-Wi-Fi handover process and it’s very likely that we will see a large 5G-to-Wi-Fi security<br />

vulnerability be exposed in <strong>2020</strong> that could allow attackers to access the voice and/or data of 5G mobile<br />

phones.<br />

Most mobile devices don’t allow the users to disable cellular to Wi-Fi handover (also known as Hotspot<br />

2.0). Windows 10 currently does, however. If unsure, individuals should utilize a VPN on their cellular<br />

devices so that attackers who are eavesdropping on cellular to Wi-Fi connections won’t be able to access<br />

your data. For businesses looking to enable Hotspot 2.0, make sure your Wi-Fi access points (APs) have<br />

been tested independently to stop the six known Wi-Fi threat categories detailed<br />

at http://trustedwirelessenvironment.com. If the APs block these threats, attackers cannot eavesdrop on<br />

the cellular to Wi-Fi handoff.<br />
