A group of academic researchers from the University of Florida and Web3 smart contract auditor CertiK have devised new attacks leading to wireless charger takeover via power supply voltage manipulation.
The theoretical attacks, dubbed
VoltSchemer (PDF), take aim at vulnerabilities in wireless charging systems that could allow adversaries to damage charging devices, manipulate voice assistants, and bypass Qi standard’s mechanisms to damage items exposed to intense magnetic fields.
The attacks, the academics note in their research paper, exploit voltage noises from the power supply and do not require malicious modifications to the chargers.
