Wireless chargers could allow crooks to hack and fry your phone.
A new study from the University of Florida discovered a mechanism called the VoltSchemer, which tries to utilize two specific properties typically present in wireless chargers.
The researchers focused on the way wireless chargers transfer information – via a magnetic field – and discovered a flaw in the device’s lack of encryption, allowing it to charge any phone.
In the process, they revealed that wireless charges are susceptible to middle-man attacks.
‘Our research discovered new vulnerabilities in wireless charging devices, rendering them vulnerable to purposeful electromagnetic interference,’ stated one of the team members.
‘These vulnerabilities facilitate a set of novel attack vectors, enabling adversaries to manipulate the charger and perform a series of attacks.’
Usually, wireless chargers are more protected than wired chargers when it comes to accessing any data pathways.
However, when the researchers modified the power signals used on Qi chargers, they could control the communication between the charger and the charged device and instruct the charger to perform malicious actions.
But that’s not all. The charger could even damage devices being charged through overcharging or overheating, effectively ‘frying’ your phone.
The researchers created ‘malicious’ power adapters that were disguised as wall USB sockets, which allowed them to create a voltage nice that could intercept and send their own commands to the wireless charger, as well as block any Qi messages sent by the smartphone.
The scary part is that the VoltSchemer requires no modification, just a place for a malicious power source in a location that could lure in anyone.
However, personal charging ports such as the one at home, or portable chargers are likely to be safe, and if you’re worried you could try using your own plug that you can attach to a power source.
